JKS Manufacturing JKS1100 Adjustable Bump Stops for 84-14 Jeep®kee XJ, Grand Cherokee ZJ, Comanche MJ, Wrangler TJ, TJ Unlimited, JK & Unlimited JK

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".
Installation of our Adjustable BumpStops is easy, and setting the desired length can be accomplished without removing the coil springs from the vehicle. This allows the user to conveniently adjust bump stop clearance as required by future changes to vehicle ride height and tire size.
Product Overview
While simple in appearance, bump stops are actually variable-rate springs that function as limiting devices for suspension compression. They are compressed between the chassis and axle under heavy impacts, effectively increasing the suspension spring rate and preventing expensive damage to the engine, fuel tank and chassis. Unfortunately, very few suspension kits address bump stops correctly as it simply isn't possible to suit every application with fixed-length designs due to individual vehicle variances.
