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

Is This for You?

You're building a loaded overlander on a JL 4-Door Unlimited and you want the top-spec Fox shock in the J-Lander lineup. The JSPEC130PES delivers JKS J-Lander overland-specific geometry with Fox 2.5 Elite DSC reservoir shocks. Driver-adjustable compression lets you compensate for the overland load on the fly — firm it up for highway stability under a fully loaded rig, open it up for trail compliance on technical terrain. The J-Lander's overland-rate coil maintains correct ride height under the combined weight of a roof tent, dual spare, full steel bumpers, winch, and recovery gear. This is the highest-performing shock configuration in the J-Lander 3.5" lineup.

The Result

3.5" of lift with JKS J-Lander geometry correction calibrated for heavily loaded JL 4-Door overland builds. Overland-rate coils maintain correct ride height under the combined weight of a fully loaded overland rig. Fox 2.5 Elite DSC shocks give you real-time compression adjustment to manage the overland load's effect on front-end dynamics on both trail and highway. Adjustable control arms allow precise alignment post-install.

Verified Fitment (OFAS Standard)

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 skid plates and body panels. No cutting or welding required for standard JL 4-Door gas applications. Confirm total rig weight with OFAS before ordering — the J-Lander's overland coil rate is calibrated for a specific load range.

Wheel & Tire Fitment

Engineered for 35"–37" tires on a loaded overland 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 — a loaded overland rig compresses the suspension more than a stock-weight build, which affects fender clearance under load.

Engineering Question

Running Fox 2.5 Elite DSC on a J-Lander 3.5" loaded JL 4-Door overland build — how does the overland-rate coil's stiffer spring rate affect the optimal DSC low-speed compression baseline compared to a J-Kontrol 3.5" HD build with the same shock and a lighter accessory load? The J-Lander's overland-rate coil is stiffer than the J-Kontrol's HD coil, which means the chassis pitches less per obstacle under the same trail conditions. A stiffer coil reduces the shock's dynamic load per compression cycle, which means the DSC low-speed circuit can be run softer on the J-Lander than on a lighter HD-coil build to achieve the same body pitch control. Contact OFAS with your total rig weight and primary terrain and we'll give you a DSC baseline starting position calibrated specifically for the J-Lander's overland coil rate and your specific loaded JL 4-Door build.
