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 a kit engineered specifically for the RHD Unlimited platform. The JSPEC104KFR 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)

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: JSPEC104KFR

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

Installing a J-Venture 3.5" RHD kit on a JK 4-Door Unlimited — how does the combination of the 4-Door's longer wheelbase, heavier curb weight, and RHD steering rack position affect front canister routing and track bar relocation compared to the RHD JK 2-Door at the same lift height? The 4-Door's longer frame rails provide more canister routing options, but the heavier platform also means the front shocks are working harder per mile, which makes remote reservoir thermal capacity more valuable than on the lighter 2-Door. Contact OFAS before your install and we'll walk you through the canister routing and alignment specs specific to your RHD JK 4-Door Unlimited at 3.5" of lift.
