JKS J-Venture 3.5" Lift Kit w/ Fox 2.5 Elite | HD Coils | 2018–2026 Jeep Wrangler JL 4-Door

Is This for You?

You want the top-spec Fox shock on your J-Venture 3.5" HD build — a fully accessorized JL 4-Door Unlimited with steel bumpers, winch, and heavy spare — without the complexity of a long-arm conversion. The JSPEC120PES delivers JKS short-arm geometry with Fox 2.5 Elite DSC reservoir shocks and HD coil springs. Driver-adjustable compression lets you tune the ride on the fly. This is the highest-performing shock configuration in the J-Venture 3.5" HD lineup.

The Result

3.5" of lift with JKS geometry-corrected short-arm control arms. HD coils handle the weight of a fully built rig without sagging. Fox 2.5 Elite DSC shocks give you real-time compression adjustment — open it up for trail compliance, firm it up for towing or highway stability. The J-Venture platform delivers serious lift performance with a straightforward install that doesn't require a differential drop.

Installation & Fabrication Notes

Short-arm system does not require differential drop or relocation. 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 skid plates and rock rails. No cutting or welding required for standard JL 4-Door gas applications.

Wheel & Tire Fitment

Engineered for 35"–37" tires on an accessorized build. 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

Running Fox 2.5 Elite DSC shocks on a J-Venture 3.5" HD short-arm build with a full steel front end — how does the DSC high-speed compression circuit interact with the HD coil rate under heavy front-end loading? At 3.5" with HD springs and a loaded front bumper, the shock's high-speed circuit is doing more work than on a stock-weight build. Contact OFAS with your bumper weight, winch model, and primary terrain and we'll give you a DSC baseline starting point before your kit ships.
