Description
The Rock Krawler JK 2.5 Ultimate Adventure Mid Arm System was designed for those who want an easy bolt-in installation, excellent on-road ride and the durability and the 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 JK factory lowers, while high misalignment adjustable upper control arms let you precision tune your JK’s caster in the front and pinion angle in the rear. Rock Krawler’s industry leading triple rate coils give you 2.5 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 JK systems include correction pads that help minimize the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in handling.
