URO URO-008904 Rear Strut Bump Stop 146.5mm | Suspension Jounce Bumper

The URO URO-008904 is a rear strut bump stop (also known as a jounce bumper or suspension bump stop) measuring 146.5mm in length. This component is a critical part of the rear suspension system, absorbing impact energy at full suspension compression to protect the strut, strut mount, bushings, and surrounding suspension components from metal-to-metal contact.

Over time, factory bump stops degrade due to age, heat cycling, and repeated compression, becoming brittle, cracked, or completely disintegrated. A failed bump stop can accelerate wear on expensive components including strut mounts, ball joints, and strut assemblies themselves. Replacing the bump stop during any strut service is strongly recommended.
