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 (718) models. Manufactured to OE specifications, it is engineered to provide progressive cushioning during extreme suspension compression while maintaining factory ride and handling characteristics.

 Installed on the front shock absorber shaft beneath the protective dust boot, the bump stop acts as a secondary suspension cushion. During heavy suspension compression caused by cornering, braking, potholes, or uneven road surfaces, the bump stop absorbs impact energy before the suspension reaches its mechanical limit. This helps prevent metal-to-metal contact and reduces stress on the damper, suspension mounts, and chassis.

The bump stop cushions the suspension when the shock absorber reaches near full compression. It helps absorb impact forces, protects suspension components from damage, and maintains stable suspension operation under demanding driving conditions.

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

Over time, suspension bump stops can deteriorate due to repeated compression, heat, moisture, and age. A damaged or collapsed bump stop may reduce suspension protection, increase harsh impacts, and accelerate wear on shock absorbers and mounting components. Replacing worn bump stops restores proper suspension cushioning and helps maintain ride comfort and handling precision.

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