JKS J-Kontrol 3.5-Inch Suspension Lift Kit with FOX 2.0 Adventure Series Shocks for 2020-2022 Jeep Wrangler JL Unlimited (Diesel)

Fits 2020-2022 Jeep Wrangler JL Unlimited 4-door models equipped with the Diesel engine. This J-Kontrol suspension system provides a 3.5-inch lift while significantly improving handling, caster, and axle positioning for superior on-road stability and trail performance.

The J-Kontrol system is a comprehensive upgrade over the J-Venture series, specifically engineered to address the geometry changes associated with higher lift heights. The kit includes heavy-duty front control arm correction brackets that flatten the upper and lower control arm angles. This design corrects caster and restores factory-like steering feel, which is often lost during suspension modification. For the heavier Diesel powertrain, JKS utilizes JSPEC dual-rate coil springs specifically tuned to provide a controlled ride and maintain proper ride height under load.

To manage damping, the kit features custom-valved FOX 2.0 Adventure Series gas shocks. These 2.0-inch IFP (Internal Floating Piston) shocks are paired with a front adjustable track bar and a rear track bar bracket to ensure both axles are perfectly centered under the chassis. Quicker-Disconnect sway bar end links are included to provide maximum articulation when the pavement ends.
