This OE Match Rubber Stop for Front Shock Absorber is a high-quality replacement component engineered to match original Porsche specifications for fit, durability, and performance. Installed on the front suspension strut, this rubber stop acts as a bump stop, preventing the shock absorber from bottoming out under heavy compression.

This component is essential for maintaining correct suspension performance and ride comfort in classic air-cooled Porsche 911 models.

This rubber stop limits suspension travel and absorbs impact forces, protecting the shock absorber and surrounding components from damage.

Function
• Acts as a bump stop for front suspension travel
• Prevents shock absorber bottoming out
• Absorbs impact forces under compression
• Protects suspension and chassis components
• Maintains ride comfort and suspension integrity

Rubber bump stops are subject to constant compression, heat, and aging, which can cause them to crack, harden, or collapse. A worn stop reduces protection for the suspension system and can result in harsh impacts, increased wear, or damage to shocks and mounts.

Replacing the rubber stop restores proper suspension cushioning and helps maintain vehicle handling and comfort.

When to replace
• Visible cracks, splitting, or deterioration
• Suspension feels harsh or bottoms out
• During shock absorber replacement
• As part of suspension overhaul or restoration
• Preventative maintenance on classic vehicles

Installed as part of the front damper/strut mounting hardware, the compensation ring acts as a precision spacer to ensure correct fitment between adjoining suspension components. By maintaining the intended tolerances and seating surfaces, it helps preserve correct suspension operation, reduces the risk of noise or play, and supports accurate alignment.

Suspension hardware relies on precise tolerances. A worn, incorrect, or missing compensation ring can affect clamping force, component alignment, and overall assembly integrity - potentially leading to noises, premature wear, or geometry changes. Using a genuine Porsche ring ensures factory-correct thickness and fit, preserving the suspension performance Porsche engineered.

When to replace:
• During front shock/strut replacement or rebuild
• Ring is corroded, distorted, or damaged during disassembly
• Persistent front-end noise traced to strut hardware (after inspection)
• Suspension work requiring correct factory stack height/spacers
• Replacing superseded part 99134351300
