JKS J-Venture 3" Lift Kit w/ Fox 2.5 | 2020–2026 Jeep Gladiator JT

Is This for You?

You're running a Jeep Gladiator JT and you want 3" of lift with the J-Venture short-arm platform and Fox 2.5 reservoir damping. The JSPEC131PS delivers JKS J-Venture geometry-corrected control arms with Fox 2.5 Performance Series reservoir shocks, engineered specifically for the Gladiator's longer wheelbase and different suspension geometry compared to the Wrangler JL. The Gladiator's truck platform and longer wheelbase require a different geometry correction approach than the JL — this kit is built for the JT, not adapted from a JL kit.

The Result

3" of lift with JKS J-Venture geometry correction calibrated for the Gladiator JT's longer wheelbase and truck suspension geometry. Fox 2.5 reservoir shocks deliver consistent damping and heat dissipation on extended trail runs. Adjustable control arms allow precise alignment post-install. The Gladiator's longer wheelbase provides a more stable platform at 3" of lift than the shorter JL, with improved approach and departure angles for truck-specific trail use.

Verified Fitment (OFAS Standard)

• Fits: 2020–2026 Jeep Gladiator JT (Sport, Mojave, Rubicon, Overland)
• Does NOT fit: Wrangler JL (any variant — 2-Door, 4-Door, 4xe, EcoDiesel) | Wrangler JK (any year)
• Platform Note: The Gladiator JT uses a different suspension geometry than the Wrangler JL. This kit is engineered specifically for the JT platform.

System Specifications

• Lift Height: 3"
• System: J-Venture Short-Arm (Gladiator JT-specific geometry)
• Shock: Fox 2.5 Performance Series w/ Reservoir
• Coil Rate: Tuned for Gladiator JT platform
• Control Arms: JKS J-Venture geometry-corrected short-arm control arms
• SKU: JSPEC131PS

Installation & Fabrication Notes

Professional 4-wheel alignment required post-installation. Torque all control arm hardware to JKS specification after a 500-mile break-in. Confirm Fox 2.5 reservoir clearance against Gladiator-specific underbody components and skid plates. No cutting or welding required for standard Gladiator JT applications.

Wheel & Tire Fitment

Engineered for 35"–37" tires on the Gladiator JT platform. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. The Gladiator's longer wheelbase provides more fender clearance than the JL at the same lift height — confirm tire brand and tread width before finalizing wheel selection.

Engineering Question

Comparing the J-Venture 3" on a Gladiator JT versus the J-Venture 3" on a Wrangler JL 4-Door at the same lift height — how does the Gladiator's longer wheelbase and truck suspension geometry affect the geometry correction requirements and the Fox 2.5 reservoir shock's performance characteristics? The Gladiator's longer wheelbase produces slower chassis pitch cycles per trail obstacle than the JL 4-Door, which means the Fox 2.5 reservoir is working at lower shaft velocities per mile of trail on the JT than on the JL. The geometry correction requirements are also different — the JT's longer control arm travel arc requires different caster correction angles than the JL. This kit is engineered specifically for the JT's geometry, not adapted from a JL kit. Contact OFAS with your Gladiator's build spec and primary terrain and we'll confirm the right configuration for your specific JT build.
