The Jeep Gladiator JT is one of the only factory-built mid-size trucks with genuine trail credentials — but its stock suspension is a compromise designed around payload ratings and street manners, not clearance. Whether you're fitting 35s, running real trails, or just correcting the factory rake, the right lift depends entirely on your trim (Rubicon vs. Non-Rubicon vs. Mojave), your lift target, and how much you care about on-road geometry afterward. This guide covers the strongest options across every use case, all in-stock at ThreePiece.us.

1. Skyjacker 4.5in Front / 3in Rear — Rubicon (G452RLT)
Skyjacker 4.5in/3in Lift — Rubicon (G452RLT) — $1163
This is the top-shelf Gladiator lift for Rubicon owners who want genuine 37-inch tire clearance without a body lift or fender trimming gamble. The asymmetric lift height (4.5in front, 3in rear) corrects the JT's factory front rake while keeping the geometry manageable with correct-length control arms. Rubicon-specific tuning accounts for the factory disconnecting sway bar and front axle geometry differences — running the Non-Rubicon version on a Rubi is a mistake you won't catch until you're on the trail. Pair with RockJock adjustable sway bar end links for proper geometry at ride height.
2. Skyjacker 4.5in Front / 3in Rear — Non-Rubicon (G452LT)
Skyjacker 4.5in/3in Lift — Non-Rubicon (G452LT) — $1171
The Non-Rubicon counterpart to the G452RLT — same lift targets, tuned specifically for Sport, Overland, and Sport S trims that lack the Rubicon's front axle disconnect and sway bar setup. If you're on a Non-Rubicon and planning 35s or 37s with a purpose-built trail rig intent, this is the right kit. The slightly higher price versus the Rubicon version reflects component differences, not a pricing error. If you want to correct steering geometry at this lift height, the RockJock Currectlync High Steer Knuckles are worth adding to the budget conversation.
3. Skyjacker 3.5in Front / 2in Rear — Non-Rubicon (G351LT)
Skyjacker 3.5in/2in Lift — Non-Rubicon (G351LT) — $1011
The sweet spot for Non-Rubicon owners who want solid 35-inch clearance without pushing into the geometry corrections required at 4.5 inches. At 3.5in front and 2in rear, you level the JT's factory nose-high stance and gain real tire room without needing extended control arms on most builds. This is also the lift range where on-road manners stay closest to stock — relevant if the Gladiator sees daily duty between weekend runs. A strong mid-budget pick that doesn't cut corners on the hardware included in the kit.
4. ReadyLift 2.5in SST Lift Kit
ReadyLift 2.5in SST Lift Kit — Gladiator — $500
ReadyLift's SST (Suspension System Technology) kits have earned a strong forum reputation for delivering real lift without the drama of a full suspension overhaul. At 2.5 inches, this is the entry point for clearing 35s with the right offset wheel and some due diligence on backspacing. It's also the most install-friendly kit on this list — a competent home builder can tackle this over a weekend. For owners who want more stance and slightly larger rubber without committing to a full rebuild, this is the honest answer at a realistic price point.
5. Skyjacker 2.5in Front / 1.5in Rear w/ Black Max Shocks — Non-Rubicon (G251PBLT)
Skyjacker 2.5in/1.5in w/ Black Max Shocks — Non-Rubicon (G251PBLT) — $756
This kit earns its place because it bundles Skyjacker's Black Max shocks into the package — meaning you're not buying a spacer lift and keeping your stock shocks (a combination that kills ride quality within 10k miles). The shocks are valved for the lifted ride height, which matters on the Gladiator's longer wheelbase where undamped compliance issues show up faster than on the JL. At $756 for a complete lift with shocks included, the value calculus here is straightforward: it's less than buying the lift and shocks separately from most sources.
6. Skyjacker 2in Dual Rate Springs — Mojave Only (G201MPELT)
Skyjacker 2in Dual Rate Lift — Mojave (G201MPELT) — $582
The Mojave is the Gladiator trim most people overlook when building — it comes from the factory with Fox shocks and a desert-tuned suspension that's different from both the Rubicon and base Non-Rubicon. Running a generic lift kit on a Mojave wrecks the factory tuning; this kit is built specifically for it. The dual-rate springs are the key detail here: they maintain the Mojave's compliance over high-speed desert terrain while adding 2 inches of clearance. If you own a Mojave and aren't running a Mojave-specific kit, you're leaving capability on the table.
7. Skyjacker 2.5in — Mojave Only (G250MMSB)
Skyjacker 2.5in Lift — Mojave (G250MMSB) — $428
The entry-level Mojave-specific option from Skyjacker — lower cost than the dual-rate G201MPELT, still correctly engineered for the Mojave's unique suspension geometry. If your Mojave build is more visual than performance-focused — bigger wheels and tires with some added stance — this delivers the lift without overbuilding for the use case. It's also the right starting point before you decide whether to invest further in shocks and arms. Don't mix this with a Non-Rubicon kit and assume it'll fit correctly; the Mojave front end has meaningful differences.
8. Falcon 3.1 Shock Kit (1.5in Lift)
Falcon 3.1 Shock Kit (1.5in Lift) — $1508
Falcon's monotube 3.1 shocks are the choice when ride quality on-road is non-negotiable and you're not chasing maximum lift numbers. The 1.5-inch lift comes from the shock body design itself — no strut spacers, no geometry compromise, no stack-up tolerances. On the Gladiator's longer wheelbase, quality damping matters more than it does on shorter-wheelbase platforms; a bad shock setup on the JT creates a choppy, unsettled feel on highway runs that gets worse as tires get heavier. These are serviceable, rebuildable, and carry a strong long-term ownership case.
9. Falcon 3.3 Shock Kit (1.5in Lift)
Falcon 3.3 Shock Kit (1.5in Lift) — $1972
The 3.3 steps up from the 3.1 with external reservoir design and adjustable damping — the version you want if the Gladiator sees mixed highway/trail use with heavier loads, overlanding gear, or a bed rack. The reservoir gives the shock significantly more thermal capacity, which translates to consistent damping on sustained washboard or repeated rock ledge impacts rather than fade after the first mile. At nearly $2,000 for a shock kit, this is a premium commitment — but for overland-focused JT owners running the truck hard, it's the right ceiling, not an extravagance.
How to choose a lift kit for the Jeep Gladiator
Trim matters before everything else. The Rubicon, Non-Rubicon (Sport/Overland/Sport S), and Mojave have meaningfully different front suspension geometry, sway bar configurations, and factory shock tuning. Running the wrong trim-spec kit creates bind, premature wear, and alignment issues that won't show up during installation — they show up at 20,000 miles.
Target tire size drives lift height. 33-inch tires are generally feasible at 2–2.5 inches with proper wheel offset management. 35s are reliable at 3–3.5 inches. Running 37s on a Gladiator with controlled clearance requires 4.5 inches of front lift and typically demands an extended upper control arm on Non-Rubicon trims to keep caster in spec.
Shocks are not optional at any real lift height. The Gladiator is a heavy truck by mid-size standards — the JT weighs over 4,600 lbs loaded. Lifting it on spacers while keeping stock shocks creates a disconnected, wallowing ride that defeats the purpose of the build. Every kit recommendation above either includes shocks or is designed to work with an upgraded shock solution like the Falcon 3.1 or Falcon 3.3.
Steering geometry at 3.5in+ requires attention. Lifts above 3.5 inches on Non-Rubicon trims typically induce bumpsteer from the factory tie rod angles. The RockJock Currectlync High Steer Knuckles and RockJock adjustable sway bar end links should be in the budget at this lift range.

Wheel offset choices also need to be revisited post-lift — the ThreePiece wheel catalog has options suited for lifted JT fitments. Browse the full suspension category for supporting parts.

FAQ
Do I need a different lift kit for the Gladiator Rubicon vs. Non-Rubicon?
Yes — this is not a marketing distinction. The Rubicon has a factory electronic front sway bar disconnect, a different front control arm configuration, and Dana 44 axle geometry that differs from the Non-Rubicon Dana 30 (or Dana 44 on upgraded trims). Skyjacker produces separate Rubicon-specific kits like the G452RLT for exactly this reason. Running a Non-Rubicon kit on a Rubicon will cause sway bar end link bind and incorrect caster angles.
What's the largest tire I can run with a 2.5in lift on the Gladiator?
With a 2.5-inch lift and correct wheel offset (typically around +0 to -12mm on a 17-inch wheel), most Gladiators will clear 35x12.50R17 tires without rubbing. Some owners report minor rub on full lock with 35s at 2.5in — a minor trim of the inner fender liner resolves it in most cases. To reliably fit 37s without rubbing, you need 4–4.5 inches of front lift and an extended upper control arm to manage caster.
Is the Mojave really that different from the standard Gladiator suspension?
Yes. The Mojave trim came from the factory with a unique Fox 2.0 shock tune, slightly different spring rates, and front track bar geometry calibrated for high-speed desert running rather than crawl-speed rock work. Using a generic Gladiator lift kit on a Mojave disrupts this calibration noticeably — the Mojave-specific kits from Skyjacker (G201MPELT and G250MMSB) exist because the demand from Mojave owners was specific enough to justify separate development.
Do I need new sway bar end links after lifting the Gladiator?
At 2–2.5 inches of lift, factory sway bar end links often remain within serviceable range. At 3.5 inches and above, they will bind under suspension travel, limiting droop and creating noise. The RockJock JL/JT Adjustable Sway Bar End Links are engineered for the JT's geometry and are the right solution at larger lift heights — don't skip them if you're running 3.5 inches or more up front.
