Increase the clearance and performance of your 4-Door Jeep Wrangler JK with a 3.5" lift J-Kontrol™ suspension system for exceptional handling and stability both on and off road. A step up from JKS J-Venture™ systems, J-Kontrol™ is a true bolt-on kit that adds front control arm correction brackets and a drag link flip kit to a J-Venture kit's list of components -- including JSPEC dual-rate coil springs, custom-valved FOX Performance Series shocks with remote reservoirs, an adjustable track bar, Quicker-Disconnect sway bar links, and more. The shock's remote reservoirs provide fade-free performance for a full day of off-road use. JKS supplies control arm brackets to further enhance on-road handling. The brackets flatten out your Jeep's control arm angles 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. Take control with J-Kontrol.
