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

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

Is This for You?

You're building a loaded overlander on a JL 4-Door Unlimited — roof tent, dual spare, heavy recovery gear, full steel bumpers, and a winch. The JSPEC130PS is JKS's overland-specific lift system, engineered for the JL 4-Door under sustained heavy accessory loads. The J-Lander's coil rate is tuned heavier than the standard HD coil to maintain correct ride height under the combined weight of a fully loaded overland rig. Paired with Fox 2.5 Performance Series reservoir shocks, this kit delivers consistent damping and heat dissipation on extended overland routes.

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 roof tent, dual spare, full steel bumpers, winch, and recovery gear. Fox 2.5 reservoir shocks deliver consistent damping and heat dissipation on extended overland routes. Adjustable control arms allow precise alignment post-install.

Verified Fitment (OFAS Standard)

• Fits: 2018–2026 Jeep Wrangler JL 4-Door (Unlimited) — Gas Models (2.0T, 3.6L)
• Does NOT fit: JL 2-Door | JL EcoDiesel | JL 4xe Hybrid | JK (any year) | Gladiator JT
• Coil Note: Overland-Rate — engineered for heavily loaded JL 4-Door builds. NOT recommended for stock-weight or lightly accessorized builds. Use J-Kontrol or J-Venture for lighter builds.

System Specifications

• Shock: Fox 2.5 Performance Series w/ Reservoir
• Coil Rate: Overland-Rate — tuned for heavily loaded JL 4-Door overland builds
• Control Arms: JKS J-Lander geometry-corrected control arms
• SKU: JSPEC130PS

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 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

Choosing between the J-Lander 3.5" and J-Konnect 3.5" for a heavily loaded JL 4-Door overland build with Fox 2.5 reservoir shocks — both deliver geometry correction at 3.5" of lift, so what's the practical difference for an overlander with a roof tent, dual spare, and full steel bumpers? The J-Lander's overland-rate coil is the key differentiator — it's tuned for the combined weight of a fully loaded overland rig, which means it maintains correct ride height and geometry under load where a standard HD coil would sag. The J-Konnect's long-arm geometry delivers superior caster correction, but its HD coil rate may not be sufficient for the heaviest overland builds. Contact OFAS with your total rig weight and accessory list and we'll confirm whether the J-Lander or J-Konnect is the right platform for your specific loaded JL 4-Door build.
