ProParts 31451162 Rear Jounce Bumper Shock Bump Rubber

The ProParts 31451162 is a replacement rear jounce bumper, also commonly referred to as a shock bumper or bump rubber. This suspension component mounts within the rear shock absorber assembly and acts as a mechanical stop, absorbing impact energy when the suspension reaches full compression to protect surrounding components and limit harsh metal-to-metal contact.

A worn or deteriorated jounce bumper can contribute to excessive bottoming-out of the suspension, increased cabin noise over rough roads, and accelerated wear on the shock absorber itself. Replacing this part restores proper suspension travel limits and helps maintain a controlled, comfortable ride.

Key Features:

• Direct-fit replacement for the rear suspension shock absorber assembly
• Designed to OEM specifications for proper fit and function
• Compatible with vehicles using OEM reference 31451162 (supersedes 31360617)
• Functions without active chassis systems (standard suspension applications)
• Also known as: jounce bumper, bump rubber, shock bumper, bump stop

This part is sold individually. Verify fitment using your vehicle's chassis number and consult your suspension diagram — this component is typically shown as position #4 in the rear shock absorber assembly.
