Are you feeling those larger bumps as you drive? You may think it's your shocks but bump stops slowly wear out over the life of a vehicle and failure can cause the lower control arm to hit the bump stop mount.

Kryptonite Bump Stops are quality-built like all Kryptonite products and will protect your suspension like nothing else. Your truck means a lot to you and Kryptonite is there to keep it riding smooth.
