Increase the clearance and performance of your 4-Door Jeep Wrangler JK with a 3.5" lift J-Kontrol™ suspension system for 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 and a drag link flip kit to the J-Venture Kit's components including JSPEC dual-rate coil springs, custom-valved FOX Adventure Series shocks, an adjustable track bar, Quicker-Disconnects, and more. Take control with J-Kontrol. The supplied control arm brackets further enhance on-road handling by flattening out the control arm to more closely mimic factory geometry while correcting caster. The Drag Link Flip Kit flattens the steering angle to mimic factory geometry. J-Kontrol offers enhanced performance for daily driving, beach cruising, or regular trail use.
