JKS J-Venture 3.5" Lift Kit w/ Fox Remote Reservoir | 2007–2018 Jeep Wrangler JK 4-Door (RHD)

JKS J-Venture 3.5" Lift Kit w/ Fox Remote Reservoir | 2007–2018 Jeep Wrangler JK 4-Door (RHD)

Is This for You?

You're running a Right-Hand Drive JK 4-Door Unlimited and you need 3.5" of lift with the thermal capacity and damping performance of a Fox remote reservoir shock on the J-Venture platform. The JSPEC100KFR delivers JKS J-Venture geometry-corrected control arms with Fox remote reservoir shocks, purpose-built for the JK 4-Door RHD's unique steering and suspension geometry. At 3.5" of lift, this kit provides clearance for 35"–37" tires while maintaining the geometry correction the RHD Unlimited platform requires. This is a dedicated RHD fitment.

The Result

3.5" of lift with JKS J-Venture geometry correction calibrated for the RHD JK 4-Door platform. Fox remote reservoir shocks maintain consistent damping performance across extended use cycles. Adjustable control arms allow precise alignment post-install. The RHD JK 4-Door's unique steering rack position, longer wheelbase, and heavier platform are all accounted for in this kit's design.

Verified Fitment (OFAS Standard)

• Fits: 2007–2018 Jeep Wrangler JK 4-Door Unlimited — Right-Hand Drive (RHD) ONLY
• Does NOT fit: JK 4-Door Left-Hand Drive (LHD) | JK 2-Door (any configuration) | JL Wrangler (2018–2026) | Gladiator JT
• Platform Note: JK production ended 2018. This kit does NOT apply to any 2019+ Wrangler.

System Specifications

• Lift Height: 3.5"
• System: J-Venture (RHD-specific)
• Shock: Fox Remote Reservoir (remote canister, extended oil volume, nitrogen charged)
• Coil Rate: Tuned for JK 4-Door RHD platform
• Control Arms: JKS J-Venture geometry-corrected control arms (RHD fitment)
• SKU: JSPEC100KFR

Installation & Fabrication Notes

Professional 4-wheel alignment required post-installation using RHD-specific alignment specs. Torque all control arm hardware to JKS specification after a 500-mile break-in. Remote reservoir canister routing must account for RHD steering rack and column placement at 3.5" of lift — confirm clearance before finalizing mount locations. No cutting or welding required for standard JK 4-Door RHD applications.

Wheel & Tire Fitment

Engineered for 35"–37" tires. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. Confirm fender clearance with specific tire brand and tread width before finalizing wheel selection.

Engineering Question

This is the final and most complex fitment in the JKS lineup — a RHD JK 4-Door Unlimited at 3.5" of lift with Fox remote reservoir shocks. How does the combination of RHD steering geometry, 4-Door wheelbase, heavier curb weight, and 3.5" of lift interact to affect front canister routing, track bar relocation, and alignment specs compared to any other JK variant in this catalog? Every one of those variables compounds. The RHD rack changes the front clearance envelope; the 4-Door wheelbase changes the control arm travel arc; the heavier platform changes the coil and shock load spec; and 3.5" of lift changes the caster correction requirement. This kit is engineered to address all of it — but the install requires careful attention to RHD-specific alignment specs and canister routing.
