If you are looking for a complete lift kit to take your Jeep Wrangler Unlimited JL 4-Door to the next level, then look no further than the JKS Manufacturing J-Krawl 3.5in Suspension System. For superior consistency and handling, this lift kit features the same front and rear dual-rate coil springs as the proven J-Venture system. The included control arms are made from 2in x .250-wall DOM tubing, and reduce Noise Vibration and Harshness (NVH) by using factory style rubber bushings. By including all eight control arms, the J-Krawl system provides optimal ride quality. The JKS Manufacturing J-Krawl 3in Suspension System is available with either JSPEC Custom Valve Gas Shocks or Fox 2.0 Performance Series Shocks. Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
