Front Lower Control Arm Bump Stop Kit, LB7 LLY LBZ LMM 2001-2010, Duramax

Replace your worn factory front bump stops. The factory bump stops or jounce bumpers located on the frame just above the front lower control arm tend to wear out or even fall out with age.

The purpose of these are to act as a secondary dampener by controlling movement as the front suspension compresses. This will also prevent harsh impact if the system bottoms out.
