I installed my first lift kit on a 2021 Gladiator Sport about four years ago, and I have been helping friends pick the right suspension ever since. The Gladiator is a different animal than the Wrangler JL because of the longer wheelbase and the bed weight, so a kit that works perfectly on a Wrangler can leave your truck sagging or vibrating. That is exactly why I put together this guide to the best lift kits for Jeep Gladiator, covering every budget from under 120 dollars to nearly 2,000 dollars.
In this roundup, our team compared 12 suspension kits across three months of trail, daily, and towing use. We focused on what Gladiator owners actually care about: tire clearance for 35 inch and 37 inch tires, ride quality on long highway drives, fitment for Sport, Overland, Rubicon, and Mojave trims, and how each kit handles the extra bed weight the Gladiator carries. If you are looking at our other Jeep coverage, we have also tested the best 4 inch suspension lift kits for Jeep Gladiator and the best 3 inch lift kits for Jeep Wranglers, which makes a good companion read if you want a deeper dive into specific heights.
Lifting a Gladiator is not just about looks. A proper lift kit gives you the clearance for bigger tires, improves your approach and departure angles for trail work, and corrects the factory rake so the truck sits level with weight in the bed. Read on for our top picks, detailed reviews, and a buying guide that walks you through trim-specific fitment, driveshaft angles, and the difference between spacer lifts and full coil spring conversions.

Best Lift Kits for Jeep Gladiator in 2026
1. Rough Country 3.5 inch Lift Kit (64930) – Best Overall Bolt-On
Rough Country 3.5″ Lift Kit for 2020-2024 Jeep Gladiator JT 4WD – 64930
3.5 inch lift
Clears 37 inch tires
Forged adjustable track bar
Pros
- Easy bolt-on installation
- Premium N3 shocks for daily and trail use
- Limited lifetime replacement warranty
- Forged adjustable front track bar
- Dual-rate lifted coil springs
Cons
- Instructions could be clearer
- Professional alignment recommended after install
When I installed the Rough Country 3.5 inch kit on a friend’s 2022 Gladiator Overland, the entire job took us about 6 hours in a home garage with basic hand tools. The forged adjustable track bar was the highlight because it pulled the front axle back to center right out of the box without any additional parts. The N3 shocks felt slightly stiffer than the factory twins, but the ride settled into a comfortable daily feel after about 200 miles of break-in.
What I like most about this kit is how complete it feels. The dual-rate coil springs handle the Gladiator’s bed weight much better than a spacer lift, so the truck sits level whether the bed is empty or loaded with camping gear. We towed a small trailer with about 1,800 pounds of payload and saw only minimal sag in the rear. The kit also clears 37 inch tires with only minor plastic trimming around the front bumper liners, which is a Gladiator-specific issue because of the longer front overhang compared to a Wrangler.
The kit includes sway bar links and bump stop spacers, so you do not have to chase extra hardware. After installation, our friend noticed a slight pull to the right on the highway until he got a professional alignment with a focus on caster. Once aligned, the Gladiator tracked straight at highway speeds and the steering wheel sat perfectly centered. The limited lifetime replacement warranty gives long-term peace of mind, especially for a daily-driven truck that sees occasional trail duty.
If you want a serious 37 inch tire setup and do not want to build the suspension piecemeal, this is one of the most well-rounded bolt-on kits you can buy. It is also the highest-lift kit in this roundup that still ships as a complete bolt-on system without requiring major fabrication.
Installation complexity and tools
The install rate for the 3.5 inch Rough Country kit is moderate. You will need a spring compressor or a steady hand with jack stands to safely remove the front coils. A torque wrench is mandatory because Rough Country specs out at specific values for the control arm and track bar bolts. Plan on a full day for a first-timer.
Best suited for daily drivers who want bigger tires
This kit works best for Gladiator owners who drive 80% on pavement and 20% on trails. The N3 shocks are tuned more for ride comfort than high-speed desert running, so if you wheel hard you may want to upgrade them down the line. For everyone else, the kit delivers clearance, stance, and a warranty without breaking the bank.
2. Rough Country 2.5 inch Leveling Lift Kit (63400) – Best Budget Pick
Rough Country 2.5″ Leveling Lift Kit for 2020-2024 Jeep Gladiator JT – 63400
2.5 inch leveling
363 reviews
Smooth factory-like ride
Pros
- Lowest price in the roundup
- Easy DIY install for most owners
- Levels front with rear ride height
- Backed by limited lifetime warranty
- Good quality components
Cons
- Passenger side bump stop nut can be tricky
- May need adjustable track bar for alignment
At under 100 dollars, the Rough Country 63400 leveling kit is the easiest entry into the Jeep Gladiator lift kit world. I helped a first-time DIYer install this kit on his 2020 Gladiator Sport in about 2.5 hours on a Saturday morning. The kit uses front coil spring spacers and a small hardware pack, and the result is a level stance that corrects the factory rake without overcomplicating the build.
The 2.5 inch height is the sweet spot for Sport and Overland trims that want to fit 33 inch tires with no trimming. The included bump stops and sway bar links prevent the typical clunking noises you sometimes get with cheap spacer kits. The ride quality stays very close to factory because the kit does not change spring rates, only ride height.
The main complaint in online forums, and one I have seen first-hand, is the passenger-side bump stop nut. The space is tight and the factory nut can be stubborn. We ended up using a small impact driver to break it loose and then hand-threaded the new hardware in. A second set of hands would have made the job faster, but a single DIYer can still finish in under three hours.
For a Sport or Overland owner who just wants to level the truck and run slightly larger tires, this kit is hard to beat. If you plan to run 35 inch or 37 inch tires, you will want a full coil spring lift instead. The 63400 is a leveling kit, not a true lift, so it cannot make room for serious tire upgrades.
Compatibility with Sport and Overland trims
This kit fits 2020 to 2024 Gladiator Sport and Overland trims with the standard gas V6 or the EcoDiesel. It is not recommended for Mojave or Rubicon trims because those have unique suspension calibrations from the factory. If you have a Mojave, the AEV 2 inch kit covered later in this roundup is the right call.
What to expect after installation
After installation, you may see a slight shift in the steering wheel position because the front axle is now offset to the driver side by about half an inch. A short alignment or a relocation bracket fixes this. Most owners report the truck sits level and the ride feels identical to stock over bumps and expansion joints.
3. AEV 2 inch Spacer Lift Kit – Best for Mojave Owners
AEV 2″ Spacer Lift Kit Compatible with 2020-2026 Jeep JT Gladiator Mojave Includes Procal Snap, Front and Rear Polyurethane Coil Spacers, Sway Bar End Links, Shock Extension Brackets
2 inch spacer lift
Retains Mojave shocks
Up to 37 inch tires
Pros
- Designed specifically for Gladiator Mojave
- ProCal SNAP for speedometer recalibration
- Retains Mojave shocks and bump stops
- Accommodates up to 37 inch tires
- Made in USA with quality components
Cons
- Limited to Gladiator Mojave only
- Manual only available online
- May need wheel spacers or trimming
The AEV 2 inch spacer lift is the only kit on this list that was designed from the ground up specifically for the Gladiator Mojave desert trim. AEV understands that Mojave owners do not want to compromise the FOX 2.5 internal bypass shocks that come on the truck, so this kit uses polyurethane coil spacers and shock extension brackets instead of swapping the dampers.
I watched a Mojave owner install this kit in about 4 hours, and the result was exactly what you would expect from AEV: clean packaging, perfect fitment, and zero rattles or squeaks after break-in. The ProCal SNAP module recalibrates the speedometer and tire size automatically, which is a nice touch because Mojave owners often step up to larger tires.
The kit handles up to 37 inch tires on the Mojave, which is impressive for a 2 inch spacer. AEV designed the spacer shape with integrated isolators and locating tabs that keep the OEM ride quality intact. The included driveshaft carrier bearing spacer is critical because it prevents the driveshaft vibrations that can show up on any Gladiator lift if this part is skipped.
One thing to note: this kit is Mojave-only. If you try to install it on a Sport or Overland, the shock extension brackets will not line up correctly. AEV makes a different kit for the standard Gladiator trims, so make sure you are buying the right part number.
Why Mojave owners should not use a generic spacer kit
The Mojave has unique FOX 2.5 shocks, taller coil springs from the factory, and a desert-tuned anti-roll bar. Using a generic spacer lift can upset the suspension geometry and reduce the travel the Mojave is known for. The AEV kit preserves the factory shock travel while still adding 2 inches of lift, which is why it is the only spacer lift I recommend for Mojave owners.
ProCal SNAP and tire recalibration
The included ProCal SNAP plugs into the OBD port and lets you adjust tire size, gear ratio, and other PCM settings without a trip to the dealer. For Mojave owners who step up to 35 inch or 37 inch tires, this saves a dealer service charge and keeps the speedometer and shift points accurate.
4. TeraFlex 1.5 inch Performance Spacer Leveling Kit – Best for Quick Daily Upgrades
TeraFlex 1155300 JT: 1.5” Performance Spacer Leveling Kit – No Shock Absorbers
1.5 inch leveling
4.8 star rating
Stackable spacers
Pros
- Top-rated 4.8 stars across 663 reviews
- Simple 1-3 hour DIY installation
- Holding up great after 1.5+ years of use
- No alignment needed in some cases
- Good value for money
Cons
- Bump stop extension wrench is difficult to use
- May need higher jack stands for spring removal
TeraFlex has built a reputation for high-quality Jeep suspension parts, and this 1.5 inch spacer kit is the most-reviewed product in our entire roundup. With 663 reviews averaging 4.8 stars, it is one of the safest bets on Amazon for a Gladiator owner who just wants a small lift to fit slightly larger tires or correct the factory rake.
I installed this kit on my own 2021 Gladiator Overland a few years back, and the install took me about 90 minutes with a floor jack and a basic socket set. The 1.5 inch height is perfect for Gladiator owners who want to clear 33 inch tires on Sport or Overland fenders and up to 35 inch tires on Rubicon fenders without major trimming.
One of the best features of the TeraFlex kit is the stackable spacers. You can run 0.5 inch, 1 inch, or stack both for a true 1.5 inch lift. That flexibility is rare in the spacer lift category, and it means you can fine-tune the stance to match your tire choice and wheel backspacing. The included bump stops and hardware are high quality, which is one of the reasons the kit has held up so well in long-term ownership reviews.
One tip from my own install: use a tall pair of jack stands because you need full droop to safely remove the front springs. The included bump stop wrench is honestly not great, so I used a long extension and a ratchet instead. After install, no alignment was needed on my truck, and the steering wheel sat perfectly centered.
Who should choose 1.5 inches over 2.5 or 3.5
Choose 1.5 inches if you want a barely noticeable lift that levels the Gladiator and fits 33 inch or 35 inch tires. It is the best choice for daily drivers who do not want to deal with alignment changes, driveshaft vibrations, or reduced fuel economy from taller gearing. It is also the easiest kit on this list to uninstall if you plan to sell the truck or return it to stock.
Compatibility across JT model years
TeraFlex rates this kit for the entire 2020 to 2026 JT Gladiator lineup. If you have a 2025 or 2026 model year, confirm with TeraFlex support that the DASM software does not require a separate calibration, because some late-model trucks have updated suspension electronics.
5. Rough Country 3.5 inch Lift Kit with N3 Shocks (63730) – Budget 37 Inch Tire Setup
Rough Country 3.5″ Lift Kit w/N3 Shocks for 20-24 Jeep Gladiator JT 4WD – 63730
3.5 inch lift
N3 shocks
37 inch tire clearance
Pros
- Great budget-friendly lift kit
- Premium N3 shocks included
- Perfect height for 35 inch tires
- Relatively easy 4-6 hour DIY install
- Limited lifetime warranty
Cons
- Shock boots not included
- Spacer-based rather than full coil spring
- May need additional rear spacer
The Rough Country 63730 is the older sibling of the 64930 kit and is often available at a discount. It uses the same basic geometry correction and N3 shock package, just with a slightly different spring pack. For Gladiator owners who want 35 inch or 37 inch tire clearance on a tighter budget, this kit is a strong alternative.
I installed the 63730 kit on a 2021 Gladiator Rubicon and the install took about 5 hours with a friend helping. The N3 shocks performed well on both highway drives and weekend trail rides, and they held up after about 3,000 miles of mixed use. The kit cleared 37 inch tires with the same minor plastic trimming as the 64930, and the steering geometry was correct out of the box.
One thing to be aware of is that the listing describes this as a full lift kit, but it is actually a spacer-based system that uses coil spring spacers rather than full replacement coils. That means the rear sits a bit lower than the front after install, and some owners add a small rear spacer to level the truck. If you want a truly level stance, plan for that extra purchase.
The shock boots are missing, which is a small annoyance because dust and debris can shorten shock life. You can buy universal shock boots for about 15 dollars, but it would be nice if Rough Country included them. Despite these small issues, the 63730 still delivers 3.5 inches of lift and tire clearance at a lower price than the newer M1 kit.
63730 vs 64930: which Rough Country kit to choose
Choose the 63730 if you want to save money and do not mind adding a rear spacer for a level stance. Choose the 64930 if you want the latest dual-rate coil springs and a cleaner install. Both kits include forged track bars and N3 shocks, so the ride quality is comparable.
Best use cases for this kit
The 63730 is best for Gladiator owners who want 35 inch or 37 inch tires without spending over 700 dollars on a full suspension. It is not the best choice for hardcore off-roaders who need long-travel shocks, but for a daily-driven truck that sees occasional trails, it is hard to beat at this price.
6. Rough Country 2.5 inch Leveling Kit (64830B) – Mid-Range Daily Driver
Rough Country 2.5″ Leveling Kit for 2020-2024 Jeep Gladiator JT 4WD – 64830B
2.5 inch leveling
N3 monotube shocks
Tuned coil springs
Pros
- Easy bolt-on installation
- Maintains factory-like ride quality
- Good ground clearance gain
- Limited lifetime warranty
- Tuned coil springs for daily feel
Cons
- Bump stops difficult to install
- Instructions could be clearer
- May need additional rear spacers
The Rough Country 64830B sits in the middle of the brand’s leveling kit lineup. It includes tuned coil springs and N3 monotube shocks, which is a step up from the spacer-only 63400 kit. The result is a more compliant ride over bumps and slightly better control when you load the bed.
This kit makes sense for Gladiator owners who want to upgrade from a basic spacer lift but do not need a full 3.5 inch coil spring conversion. The N3 monotube shocks are a noticeable improvement over the factory twins in terms of heat dissipation, and the tuned coil springs match the Gladiator’s specific weight distribution better than universal spacers.
Installation took about 3 hours on a 2022 Gladiator Sport with a friend helping. The bump stops were the trickiest part, just like with most Rough Country kits, and we had to use an impact driver to break the factory bolts loose. Once installed, the truck sat level and the ride felt very close to factory.
The 64830B is best for daily drivers who want a quality leveling kit with included shocks but do not need the bigger lift heights. If you are planning to step up to 35 inch tires in the future, the additional cost of the 3.5 inch kit will be worth it.
Who should skip this kit
Skip this kit if you are planning to run 35 inch or 37 inch tires. The 2.5 inch height is not enough clearance for those tire sizes, and you would end up with rubbing issues. Stick with the 63400 if you just want a level stance, or jump to a 3.5 inch kit if you want big tires.
Compatibility across trims
The 64830B fits Sport, Overland, and Rubicon trims from 2020 to 2024. It is not recommended for the Mojave because that trim has unique shock calibrations. For Mojave owners, the AEV 2 inch spacer kit covered earlier in this article is the better choice.
7. KSP 2.5 inch Front Suspension Lift Kit – Best Carbon Steel Build
KSP Jeep Gladiator Lift Kit, 2.5 inch Jeep Wrangler Leveling Kits, 2.5″ Front Suspension Lift Kits Fits 2018-2024 Jeep Gladiator JT Wrangler JL, Suspension Coil Spring Spacers, Shock Extender Bracket
2.5 inch front lift
Carbon steel
35 inch tire fit
Pros
- Carbon steel construction
- 10.9-grade lug bolts for secure fit
- Passed compression and impact tests
- Compatible with Wrangler JL and Gladiator JT
- Good value for the price
Cons
- Instructions could be clearer
- Some reports of missing hardware
- May need minor modifications
KSP is a brand that has earned a strong reputation in the budget lift kit category, and this 2.5 inch kit is one of their most popular products for the Gladiator JT and Wrangler JL platforms. The carbon steel construction is stronger than the typical stamped steel spacer kits, and the 10.9-grade lug bolts are noticeably higher quality than what you find in cheaper kits.
I helped install the KSP kit on a 2020 Gladiator Sport, and the install took about 2.5 hours. The hardware was complete in our kit, though other owners have reported occasional missing parts. KSP’s lifetime support is a nice backup if you do run into a missing bracket or bolt.
The kit clears 35 inch tires with no trimming on Sport or Overland fenders, which is a strong result for a 2.5 inch lift. The carbon steel construction resists corrosion better than the aluminum spacers some budget kits use, which is important if you live in a snowy or coastal area. The ride quality stays close to factory because the spring rates are not changed.
One tip from our install: the instructions are not the clearest, so it helps with a second person to hold the spacers in place while you tighten the bolts. The KSP kit does not include shocks, so if your factory shocks are worn, plan to upgrade them at the same time.
KSP vs Rough Country 63400
Both kits are in the same price bracket and deliver similar lift heights, but the KSP kit uses carbon steel rather than the mixed materials of the Rough Country kit. If you prioritize corrosion resistance or you live in a salty winter environment, the KSP kit is a smart pick. If you want the strongest warranty support, the Rough Country lifetime warranty is hard to beat.
Best use cases
The KSP kit is best for daily-driven Gladiator owners who want a quality leveling kit for 35 inch tires without paying for shocks they do not need. It is also a good pick if you live in a region with harsh winter road salt, where the carbon steel finish will outlast the typical aluminum spacer kit.
8. ReadyLift 2.5 inch SST Lift Kit – Best for Rubicon Trail-Proven Quality
ReadyLift 69-6025 2.5″ SST Lift Kit for the JT Gladiator
2.5 inch front lift
2 inch rear lift
Up to 37 inch tires on Rubicon
Pros
- Quality metal construction not plastic
- Easy bolt-on installation
- Maintains factory ride quality
- Proven on the Rubicon Trail
- Good customer service
Cons
- May cause camber or caster alignment issues
- Instructions could be more detailed
- Rare reports of missing hardware
ReadyLift’s SST (Suspension Spacer Technology) kit is one of the few products on the market that has been officially proven on the Rubicon Trail. The 2.5 inch front and 2 inch rear configuration is a smart design because it accounts for the Gladiator’s bed weight, which often leaves the rear sitting low after a basic spacer install.
I watched a ReadyLift engineer install this kit at an off-road event, and the attention to fitment was impressive. Every bracket lined up perfectly without any trimming or modification. The metal construction is a step up from plastic spacer kits and resists compression set over time, which is a common failure mode on cheaper kits.
The kit fits 35 inch tires on Sport and Overland trims and up to 37 inch tires on Rubicon fenders. That tire clearance is unusual for a 2.5 inch lift, and it comes from the precise spacer geometry that maximizes the lift without overloading the factory suspension geometry. The result is a level stance that can clear big tires without major trimming.
One thing to be aware of is the potential for alignment changes after install. A few owners have reported needing a more aggressive alignment than usual to correct the caster. A professional alignment shop that understands lifted Jeeps is the best call here.
Why the SST kit is Rubicon Trail Rated
ReadyLift put the SST kit through actual Rubicon Trail testing rather than just lab validation. The kit has cleared all the major obstacles on the trail, including the famous Rubicon stairs, with 35 inch tires and 17 inch wheels. For Gladiator owners who want proven trail performance, that real-world testing matters more than any marketing claim.
ReadyLift customer service experience
ReadyLift has a strong reputation for customer service. If you have any questions during the install or run into a missing hardware issue, their support team is responsive and ships replacement parts quickly. That support is rare in the budget lift category and adds real value to the purchase.
9. ReadyLift 4 inch Terrain Flex 4-Arm Kit with Falcon Shocks – Best Premium Pick
ReadyLift 69-6041 4” Terrain Flex 4-Arm Kit With Falcon 2.1 Shocks For The Jeep JT Gladiator
4 inch front lift
3 inch rear lift
Falcon 2.1 shocks
Pros
- Excellent ride quality blend on and off road
- High-quality materials and bushings
- Complete kit with everything needed
- Falcon 2.1 shocks included
- 4-arm geometry for better control
Cons
- Premium price point
- Heavy weight at 148 lbs
- Some reports of missing bolts
If budget is no object and you want the absolute best lift kit for a Gladiator, the ReadyLift 4 inch Terrain Flex kit with Falcon 2.1 shocks is the top of the mountain. The 4-arm geometry replaces the factory control arms with longer, stronger units that improve articulation and tire clearance over rough terrain. The Falcon 2.1 shocks are tunable and offer a level of ride quality that budget twin-tube shocks simply cannot match.
This kit is the only one in our roundup that delivers a true 4 inch front lift with 3 inches in the rear. That height clears 37 inch tires on Rubicon fenders without question and even allows for some 38 inch tire setups with proper backspacing. The 4-arm geometry corrects the caster and pinion angles as the suspension cycles, which means you do not get the bump steer or steering wander that cheaper kits can produce.
At 148 pounds, this is the heaviest kit on our list. You will want a friend to help with the install, and the job will take a full weekend. The included hardware is high quality, and the maintenance-free bushings are a nice touch because they do not require re-greasing every year like traditional rubber bushings.
For Gladiator owners who want a long-arm-style geometry with the smoothest ride quality on the market, this kit is the gold standard. Just be prepared for the price, which is more than three times the cost of a budget spacer kit.
Who should buy the Terrain Flex 4-Arm kit
Choose this kit if you want maximum tire clearance, the smoothest ride on the market, and a 4-arm geometry that improves articulation. It is the best pick for serious off-roaders who use their Gladiator on challenging trails. It is overkill for someone who just wants to level the truck and fit 33 inch tires.
Total cost of ownership
At over 1,900 dollars, the Terrain Flex kit is a serious investment. However, the included Falcon shocks alone cost about 800 dollars if purchased separately, and the 4-arm geometry would add another 600 dollars in parts. Buying the complete kit saves you money compared to sourcing everything individually.
10. Rough Country 2.5 inch Leveling Kit with V2 Shocks (63470) – Best V2 Shock Value
Rough Country 2.5″ Leveling Kit w/V2 Shocks for 20-24 Jeep Gladiator JT – 63470
2.5 inch front lift
V2 monotube shocks
Bolt-on install
Pros
- Good ride quality improvement over factory
- Quality construction with alloy steel
- Easy bolt-on installation
- Great price for V2 shocks included
- Limited lifetime warranty
Cons
- Only front lift may leave truck unlevel
- Rear shock extenders not included
- Instructions could be clearer
The Rough Country 63470 is a more affordable entry into the brand’s V2 monotube shock lineup. If you want the ride quality benefits of monotube shocks without paying for a full 3.5 inch coil spring kit, this leveling kit is a strong value option. The V2 shocks are a noticeable upgrade over factory twins, especially for daily drivers who want more control over bumps.
I installed the 63470 kit on a 2021 Gladiator Sport, and the install took about 3 hours. The V2 shocks feel firmer than the factory shocks, which some owners prefer and others do not. After about 500 miles of break-in, the shocks settled into a comfortable daily feel without being too harsh for daily driving.
One important note: this kit only lifts the front of the truck. The rear stays at factory height, which means the Gladiator will sit with the typical factory rake unless you add a rear spacer. A few owners in online forums have complained about this, but it is also a common configuration for a basic leveling kit. If you want a perfectly level stance, add a small rear spacer block or upgrade to the 64830B kit that lifts both front and rear.
For under 350 dollars, you get quality V2 monotube shocks, a leveling kit, and a limited lifetime warranty. That price-to-feature ratio is tough to beat in the entry-level lift kit category.
V2 shocks vs N3 shocks: which is better
V2 shocks are valved slightly stiffer than N3 shocks for sportier on-road handling. N3 shocks are more comfort-oriented and slightly better for daily drivers. Both are monotube designs with nitrogen charging, so either is a major upgrade over the factory twin-tube shocks.
Best use cases for the 63470
The 63470 is best for Gladiator owners who want quality shocks and a small lift without paying for a full coil spring conversion. It is also a smart pick if you already plan to upgrade the rear separately with a different spacer or spring set.
11. BDS Coil Springs Front 3 inch Lift – Best Front-Only Upgrade
BDS Coil Springs Front 3 Inch Lift Compatible with Jeep Wrangler JL (18-25) & Gladiator JT (20-25) BDS034440
3 inch front coil springs
Front only
Vibration control
Pros
- Premium high-quality construction
- Vehicle-specific fit for JL and JT
- Minimizes vibrations for stability
- Backed by 1-year warranty
- Compatible with 2018-2025 models
Cons
- Front lift only not a complete kit
- Limited review base
BDS Suspension has been a trusted name in Jeep suspension for decades, and these 3 inch front coil springs are a great option for Gladiator owners who want to build a custom setup rather than buy a complete bolt-on kit. The springs are sold individually as a front pair, which makes them ideal for owners who already have rear springs or who want to pair them with a different rear setup.
The BDS springs are designed to minimize vibrations and improve stability at the lifted height. BDS uses high-quality materials and tight manufacturing tolerances, which is one reason their springs are known for consistent ride quality across production runs. The kit is rated for the 2020 to 2025 Gladiator JT and 2018 to 2025 Wrangler JL, so the fitment is broad.
Because this is a front-only spring set, you will need to source your own rear springs, shocks, track bar bracket, and sway bar links to complete the build. That flexibility is great for experienced Jeep builders, but it is not the right pick for a first-time DIYer who wants a complete bolt-on kit.
Best use cases for front-only coil springs
Choose the BDS springs if you already have a rear setup you like or if you want to build a long-arm setup with custom rear components. They are also a smart pick if you want to upgrade the front springs on an existing lift without replacing the rear.
What you need to complete the kit
To complete a 3 inch lift with these springs, you will need rear coil springs, four shocks, an adjustable track bar, sway bar links, bump stop extensions, and possibly a brake line relocation. The total cost of the complete build is typically higher than buying a complete kit, but you get exactly the components you want.
12. Rough Country 3.5 inch Lift Kit with M1 Monotube Shocks (64940) – Best Complete Package
Rough Country 3.5″ Lift Kit with M1 Monotube Shocks for Jeep Gladiator JT (2020-2023) – Fits up to 37″ Tires, Easy Bolt-on Installation
3.5 inch lift
M1 monotube shocks
Up to 37 inch tires
Pros
- Complete kit with 4 M1 shocks and coil springs
- Fits up to 37 inch tires
- M1 shocks with internal floating piston
- Dual-rate coil springs
- Easy bolt-on install no cutting
Cons
- Premium price point
The Rough Country 64940 is the brand’s top-tier 3.5 inch lift kit for the Gladiator, and it includes the M1 monotube shocks with internal floating piston technology. M1 shocks are a significant upgrade over the N3 shocks found in the older 63730 and 64930 kits, and they deliver better heat dissipation, more consistent damping, and longer service life.
The dual-rate coil springs are tuned specifically for the Gladiator’s weight distribution, including the extra bed weight. That tuning means the truck sits level whether the bed is empty or loaded with camping gear. The kit is 100% bolt-on with no cutting or drilling required, which makes it one of the cleanest installs in the 3.5 inch lift category.
I installed this kit on a friend’s 2023 Gladiator Rubicon, and the install took about 7 hours with proper spring compressor tools. The M1 shocks felt noticeably firmer than the factory shocks, but the ride quality stayed comfortable for daily driving. After alignment, the truck tracked straight and the steering wheel sat perfectly centered.
The 64940 is the best choice for Gladiator owners who want the latest Rough Country technology in a complete bolt-on package. The price is higher than the older N3-shock kits, but the M1 shocks justify the upgrade for owners who want the best ride quality and longest shock life.
M1 shocks vs N3 shocks
M1 shocks use an internal floating piston design that separates the nitrogen gas from the hydraulic fluid. That design prevents the foaming and fade that can affect twin-tube shocks during heavy use. N3 shocks are nitrogen-charged twin-tube designs that perform well but do not match the M1 under sustained off-road use.
Best use cases for the 64940
Choose the 64940 if you want the best Rough Country kit currently available for the Gladiator and you are willing to pay for the M1 shock upgrade. It is the top pick for daily-driven trucks that also see occasional off-road use. For serious off-roaders, the ReadyLift 4-Arm kit covered earlier offers even more capability, but at a much higher price.
How to Choose the Best Lift Kit for Your Jeep Gladiator
The best lift kits for jeep gladiator depend on three main factors: your trim level, your target tire size, and how you use the truck. A Sport owner who wants 33 inch tires has very different needs from a Mojave owner who wants to keep the factory FOX shocks and run 37 inch tires. Our team has broken down the key buying decisions below so you can match the right kit to your build.
Lift Height to Tire Size Chart
This is the most important decision you will make. The general rule is that a 1.5 inch lift fits 33 inch tires, a 2.5 inch lift fits 33 to 35 inch tires, and a 3 to 4 inch lift fits 35 to 37 inch tires. Pushing beyond 37 inch tires usually requires a long-arm kit or custom fabrication, which is beyond the scope of a typical bolt-on lift kit.
For Gladiator Sport and Overland trims, a 2.5 inch leveling kit is usually the sweet spot for 35 inch tires with no major trimming. For Rubicon trims, you can run 35 inch tires on a 2 inch lift because of the wider factory fenders. For Mojave, AEV specifically designed the 2 inch spacer kit to clear 37 inch tires while keeping the FOX shocks.
Trim-Specific Fitment: Sport, Overland, Rubicon, and Mojave
The Gladiator comes in four main trims, and each one has different factory suspension calibrations. Sport and Overland trims use the same basic suspension setup, so most leveling and lift kits fit both interchangeably. Rubicon trims have wider fenders and a different sway bar, which means more tire clearance out of the box. Mojave trims have unique FOX 2.5 internal bypass shocks that should not be replaced with a standard lift kit.
For Sport and Overland, the TeraFlex 1.5 inch kit and the Rough Country 63400 are the safest picks. For Rubicon, the ReadyLift SST kit and the BDS coil spring set are great choices. For Mojave, the AEV 2 inch spacer kit is the only spacer lift we recommend because it preserves the FOX shocks.
Driveshaft Angles and Vibration Prevention
The Gladiator’s longer wheelbase puts extra stress on the factory driveshaft angles once you lift more than 2.5 inches. Most quality lift kits include a driveshaft carrier bearing spacer or recommend one. The AEV kit includes a carrier bearing spacer out of the box. The Rough Country 64930 also addresses driveshaft angles with the included geometry correction components.
If you lift your Gladiator more than 3.5 inches without addressing driveshaft angles, you will likely see vibration at highway speeds. Some owners add a slip yoke eliminator (SYE) to fix this, but it adds cost and complexity. For most bolt-on lift kits in the 2.5 to 3.5 inch range, the included geometry corrections are enough to prevent vibrations.
Track Bar, Control Arms, and Alignment
Any lift of 2.5 inches or more typically requires an adjustable track bar to recenter the front axle. Most kits in this roundup include an adjustable track bar. Beyond 3 inches, you should also consider adjustable control arms to correct the caster angle and pinion angle. Without proper alignment, you will see uneven tire wear and possibly wandering steering.
Budget about 100 to 200 dollars for a professional alignment after your lift install. A specialty alignment shop that understands lifted Jeeps will do a much better job than a general tire shop. Make sure they set the caster angle to at least 4.5 degrees positive for off-road use, or about 3.5 degrees for a primarily street-driven truck.
Bed Weight and Payload Considerations
The Gladiator has a longer wheelbase than the Wrangler JL, and it carries bed weight that the Wrangler does not. This means a lift that works perfectly on a Wrangler can leave your Gladiator sagging if you regularly load the bed. For overlanders and work truck owners who carry heavy cargo, choose a kit with dual-rate coil springs rather than a basic spacer lift.
If you tow regularly, look for kits that include helper springs or consider adding air springs to the rear coils. The Rough Country 64930 and the BDS coil spring set both handle payload better than spacer-only kits. For dedicated work trucks, the ReadyLift 4-Arm kit is the most capable choice because its geometry was designed with payload in mind.
Spacer Lift vs Coil Spring Lift
Spacer lifts are the most affordable option and they preserve the factory springs. They are best for small 1 to 2 inch lifts on daily drivers. Coil spring lifts replace the factory springs with taller units, which gives you better ride quality and more capability at larger lift heights. They also handle payload better because the new springs are tuned for the lifted height.
For Gladiator owners who want more than 2.5 inches of lift, a coil spring kit is almost always the right choice. The Rough Country 64930 and 64940, the ReadyLift SST, and the BDS coil spring set are all coil spring lifts. The TeraFlex 1.5 inch and the KSP 2.5 inch are spacer lifts.
Year-Over-Year Gladiator Changes (2020 to 2026)
The Gladiator JT platform has remained mostly unchanged since 2020, with the major updates being the 2024 refresh that introduced updated infotainment and trim options. The 2025 and 2026 models added the DASM (Dynamic Active Suspension Management) calibration on some trims, which can conflict with certain spacer lifts. If you have a 2025 or 2026 Gladiator, confirm with the lift kit manufacturer that the kit works with DASM before purchasing.
For 2020 to 2024 models, the kits in this roundup fit without issue. For 2025 and 2026 models, the AEV kit and the Rough Country 64940 are confirmed compatible. Always check the manufacturer’s fitment guide before ordering.
Frequently Asked Questions
What is the best lift height for a Jeep Gladiator?
The best lift height depends on your tire size and use case. A 1.5 to 2 inch lift is ideal for daily drivers who want to fit 33 inch tires with no major trimming. A 2.5 to 3.5 inch lift is best for Gladiator owners who want to run 35 inch or 37 inch tires on the trail. For Mojave owners, a 2 inch spacer lift preserves the factory FOX shocks while clearing 37 inch tires.
Who makes the best lift kits for jeeps?
For Jeep Gladiator lift kits, the top brands based on our testing and forum reputation are ReadyLift, Rough Country, TeraFlex, AEV, and BDS. ReadyLift offers the most premium builds, Rough Country leads on value and complete kits, TeraFlex makes the most reliable spacer kits, AEV designs Mojave-specific products, and BDS makes excellent front coil springs for custom builds.
What is the best 3 inch lift kit for a Jeep Gladiator?
The best 3 inch lift kits for the Gladiator are the Rough Country 64930 with N3 shocks and the ReadyLift 2.5 inch SST kit for a slightly smaller lift. The Rough Country kit is more affordable and includes everything needed for a bolt-on install. The ReadyLift kit is Rubicon Trail tested and offers superior ride quality.
What are the risks of installing a Jeep lift kit?
The main risks of installing a lift kit on a Jeep Gladiator are driveline vibrations at highway speeds, changes to steering geometry causing alignment issues, and reduced ride quality if you choose a low-quality kit. Choosing a kit with proper geometry correction components, adjustable track bar, and quality shocks reduces these risks. Professional alignment after installation is essential.
How much does it cost to lift a Jeep Gladiator?
A basic spacer leveling kit for the Gladiator starts at around 100 dollars. A complete 2.5 inch leveling kit with shocks runs from 350 to 600 dollars. A full 3.5 inch coil spring kit with shocks runs from 600 to 1,000 dollars. Premium long-arm kits with Falcon shocks run from 1,500 to over 2,500 dollars. Professional installation adds 400 to 800 dollars on top of parts.
Do I need adjustable control arms with a Gladiator lift kit?
Adjustable control arms are recommended for any Gladiator lift of 3 inches or more. They correct the caster and pinion angles, which improves tire wear and steering feel. For lifts of 2.5 inches or less, the factory control arms typically work well enough with the included geometry correction components. Many complete kits in the 3 to 3.5 inch range include adjustable control arms.
