JKS J-Venture 4" Lift Kit w/ Fox 2.5 Elite DSC | 2020–2026 Jeep Gladiator JT

Is This for You?

You're running a Jeep Gladiator JT and you want 4" of lift with the J-Venture short-arm platform and the top-spec Fox shock in the lineup. The JSPEC131PES delivers JKS J-Venture geometry-corrected control arms with Fox 2.5 Elite DSC reservoir shocks, engineered specifically for the Gladiator's longer wheelbase and truck suspension geometry. Driver-adjustable compression lets you dial in the shock for trail compliance or highway stability on the fly. At 4" of lift, the Gladiator JT gains meaningful tire clearance for 37"+ tires and improved approach and departure angles for truck-specific trail use.

The Result

4" of lift with JKS J-Venture geometry correction calibrated for the Gladiator JT's longer wheelbase and truck suspension geometry. Fox 2.5 Elite DSC shocks give you real-time compression adjustment to manage the Gladiator's heavier truck platform on both trail and highway. Adjustable control arms allow precise alignment post-install. The Gladiator's longer wheelbase provides a stable platform at 4" of lift 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 at 4" of lift.

System Specifications

• Shock: Fox 2.5 Elite w/ DSC (Dual Speed Compression) Reservoir
• Coil Rate: Tuned for Gladiator JT platform at 4" of lift
• Control Arms: JKS J-Venture geometry-corrected short-arm control arms
• SKU: JSPEC131PES

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 DSC adjuster knob placement for driver accessibility during install. Verify 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 37" tires on the Gladiator JT platform at 4" of lift. 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. Contact OFAS for 40" tire clearance confirmation at 4" of lift.

Engineering Question

Running Fox 2.5 Elite DSC on a J-Venture 4" short-arm Gladiator JT build — how does the Gladiator's longer wheelbase and heavier truck platform affect the optimal DSC high-speed compression baseline compared to a J-Venture 3" on the same JT platform? At 4" of lift, the Gladiator's longer control arm travel arc produces different chassis pitch dynamics than at 3", and the additional lift height increases the lever arm effect on the shock under trail impacts. The DSC high-speed baseline that works at 3" may need adjustment at 4" to account for the increased shock velocity at the higher lift height. Contact OFAS with your Gladiator's build spec, accessory weight, and primary terrain and we'll give you a DSC starting position calibrated specifically for the JT platform at 4" of J-Venture lift.
