Description
Improve the ground clearance and off road capability of your 4 Door Jeep Wrangler JL with the JKS J-Kontrol 3.5 inch suspension system.
The J-Kontrol system retains your OE control arms, but steps up the rest of your suspension. J-Kontrol kits feature dual rate coil springs, adjustable front track bar, specially-valved gas shocks, sway bar Quicker Disconnects, and front control arm correction brackets as well as all other necessary hardware for a complete bolt-on installation.
J-Kontrol system's front control arm correction brackets further enhance the on-road handling by flattening out the control arm to more closely mimic factory angles while correcting caster. With a matched combination of parts, J-Kontrol systems offer very solid performance without compromising daily-driver comfort.
If you spend a good amount of time on the trails, take control with J-Kontrol.
