JKS Jeep JL 4-door J-Kontrol 3.5" Kit

Increase the clearance and performance of your 4-Door Jeep Wrangler JL with a 3.5" lift J-Kontrol™ suspension system. It delivers exceptional stability on and off road. A step up from JKS J-Venture™ systems, J-Kontrol™ is a true bolt-on system that adds in front control arm correction brackets to the J-Venture Kit's long list of upgrade components including JSPEC dual-rate coil springs, custom-valved aluminum FOX 2.0 Performance Series gas shocks, a front adjustable Track Bar and rear Track Bar Bracket (to correct axle positioning under vehicle), Quicker-Disconnect sway bar end links, front/rear Bump Stop Extensions and front Control Arm Correction Brackets to flatten upper/lower control arm angles. The supplied control arm brackets work with your Jeep's stock control arms to correct caster and improve handling. J-Kontrol offers enhanced performance for daily driving, beach cruising, or regular trail use.
