3.5" 2020-2026 Jeep Wrangler JL Diesel / 392 (4 Door) J-Kontrol Lift Kit by JKS

The JKS J-Kontrol 3.5" suspension system for 4 Door Diesel Jeep Wrangler JL models improves ground clearance and off-road capability while maintaining balanced on-road performance. Designed as a complete bolt-on suspension lift kit, this system delivers increased control and stability for drivers who spend time both on pavement and on the trail.

The J-Kontrol system retains factory control arms while upgrading key suspension components for improved geometry and handling. Front control arm correction brackets are included to flatten upper and lower control arm angles, correcting caster and helping the suspension more closely mimic factory geometry. This results in improved steering feel, enhanced stability, and more confident handling at highway speeds.

Dual-rate coil springs are engineered to deliver excellent ride quality across a wide range of terrain, providing a smooth and controlled ride during normal driving with increased performance as suspension travel increases. An adjustable front track bar and rear track bar bracket are included to properly recenter the axles after lifting, while front sway bar Quicker Disconnects and rear sway bar links increase articulation during off-road use.

The system offers a selection of custom-valved shock options to match driving style and terrain, including FOX Adventure Series, FOX 2.0 Performance Series, FOX 2.5 Performance Series, and FOX 2.5 Elite Series shocks. Front and rear bump stop extensions are included to properly limit suspension up-travel and protect components, resulting in a well-matched suspension package that delivers solid trail performance without compromising daily-driver comfort.
