Rusty's 4" kit gives the classic CJ the clearance for 33 to 35 inch tires. Rusty's CJ spring packs are constructed with bolt-style retaining clips for excellent ride quality and flexing characteristics, while nylon anti-friction pads are positioned between each leaf to further optimize ride quality. Unlike many other spring packs on the market, Rusty's springs also feature full military wraps for excellent strength and support. Only Rusty's has the high quality springs you demand at unbelievable prices! We also include steel 6-degree rear axle shims to correct rear driveline angle; most other kits on the market use failure-prone aluminum shims, if shims are included at all. New U-bolts and Rusty's Hydro shocks round out this kit, which can breath new life into your CJ's tired suspension. This kit can be used with a SOA (Spring Over Axle) conversion as well.
Several options are available to round out this suspension kit. Extended-length stainless steel brake hoses are available that will provide the extra length needed to work with the suspension lift. Rusty's also offers a heavy-duty steering stabilizer to help smooth out the steering on the street. Speaking of steering, Rusty's recommends the use of a dropped pitman arm with this amount of lift. However, note that the Drop Pitman Upgrade is for power steering only!
