Front shock absorber bump stop. Porsche 981 / 991 / 982  ❭  99134330103

Front shock absorber bump stop.
This Front Shock Absorber Bump Stop is an OE-style front suspension cushioning component designed for Porsche 981, 991, and 982 models equipped with PASM suspension systems. The bump stop cushions the suspension when the shock absorber approaches full compression. It absorbs impact forces, protects suspension components from excessive load, and helps maintain stable ride comfort and handling performance.

This OE match front shock absorber bump stop is a direct replacement for the original Porsche suspension component fitted to selected Porsche 981 Boxster/Cayman, 991 Carrera/Turbo, and 982 Boxster/Cayman models. Manufactured to OE specifications, it is engineered to provide progressive cushioning during heavy suspension compression while preserving factory ride quality and handling precision.

Installed on the front shock absorber shaft beneath the protective dust boot, the bump stop acts as a secondary suspension damper. During aggressive cornering, braking, uneven road conditions, or pothole impacts, the bump stop absorbs excess compression energy before the suspension reaches its mechanical limit. This helps prevent metal-to-metal contact and reduces stress on the shock absorber, suspension mounts, and chassis components.

This component is commonly replaced during shock absorber servicing, suspension refurbishment, or preventative maintenance to restore proper suspension protection and ride refinement.

Function
•  Cushions front suspension at full compression
•  Protects shock absorbers from excessive impact loads
•  Prevents metal-to-metal suspension contact
•  Helps maintain stable ride quality and handling
•  Reduces stress on suspension mounts and chassis components

Over time, bump stops can deteriorate due to repeated compression, age, heat exposure, and road contamination. A damaged or collapsed bump stop may allow harsh suspension impacts, increased vibration, and premature wear of the shock absorber and mounting components. Replacing worn bump stops restores suspension protection, ride comfort, and correct damper operation.

When to replace
•  Cracked, crumbling, or compressed bump stop material
•  Harsh impacts or bottoming-out sensation
•  Increased suspension noise or vibration
•  During shock absorber replacement or suspension servicing
•  Preventative maintenance on higher-mileage vehicles
