The Rock Krawler Suspension JT 1.5 inch ADVENTURE Mid-Arm System was designed for those who want an easy bolt-in installation, excellent on-road comfort and the durability and off-road performance you expect from Rock Krawler Suspension. This kit features Rock Krawler’s proven, service free control arm joints. These joints are the industry leader in service free control arm joints using innovative technology to provide the best possible ride in your Wrangler. The Adventure Series fixed lower control arms offer a total of 70 degrees of misalignment that greatly reduces the bind inherent in JT factory lowers. Rock Krawler’s industry leading triple rate coils give you 1.5 inches of lift to clear up to 38 inch tires, depending on model, and improve the on-road ride over the factory linear rate springs. All Rock Krawler JT systems include correction pads that help minimize the spring bow inherent in the factory set up. The provided track bar geometry corrections lets you perfectly center the axle so there is no compromise in handling.

When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail!  Thank you for considering Rock Krawler Suspension
