Jounce bumpers play a critical role in suspension performance by cushioning the shock absorber during extreme compression events, such as hitting bumps or potholes. Over time, these components can deteriorate from heat, road chemicals, and constant compression cycles, leading to harsh bottoming out and potential damage to other suspension parts. This genuine ACDelco component ensures proper fitment and long-lasting performance for your GM vehicle's rear suspension system.
