Adjustable BumpStops from JKS eliminate the guessing game of choosing the proper bump stop lengths for your application. This innovative solution utilizes a system of three interlocking billet aluminum spacers, each a different size.

The spacers can be used independently, or together, to ensure the proper bump stop clearance for any suspension lift and tire combination. Although supplied in three individual sizes, JKS Adjustable BumpStops actually provide six possible bump stop lengths: 0.75", 1.25", 2.00", 2.75", 3.25", and 4.00".

Adjustable rear bump stops for your XJ. Includes new 1/2" thick U-Bolt plates that incorporate a built-in bump stop extension.
