BMW Jounce Bumper - Febi Bilstein 33536855439

Product Information

This rear suspension jounce bumper (bump stop) plays a critical role in protecting your BMW’s chassis and suspension components. It prevents bottoming out by absorbing and dissipating impacts when driving over harsh bumps, potholes, or carrying heavy loads.

Constructed from durable polyurethane foam rubber, this component provides both stiffness and resilience to withstand repeated compression. In some applications, bump stops also act as a secondary spring, contributing to the vehicle’s handling and stability.

It is recommended to replace bump stops whenever you replace struts or shock absorbers to maintain proper suspension performance and prevent premature wear.

Failure symptoms may include:
– Visible cracks, splits, or deterioration of the rubber
– Flattening or compression from frequent use
– Clunking or knocking sounds during extreme suspension travel
– Oil leaks (in the case of hydraulic bump stops)
