The concave washer sits within the shock absorber mounting assembly and helps evenly distribute clamping force across the suspension components. Its specially formed curved profile supports the correct positioning of the shock absorber mount, helping maintain suspension geometry and reducing stress on mounting surfaces during suspension movement.

Functions & Technical Role
•  Load distribution: Spreads suspension forces evenly across mounting points
•  Mounting support: Assists correct positioning of the shock absorber assembly
•  Suspension stability: Helps maintain proper suspension alignment under load
•  Vibration control: Reduces stress and movement within the mounting assembly
•  OEM precision: Manufactured to Porsche specifications for exact fitment and durability

Fitment / Position on car
•  Fitting position: Front axle suspension
•  Location: Shock absorber / strut mounting assembly
•  System: Front suspension and damping system

The concave washer supports correct suspension mounting geometry and helps prevent uneven stress on suspension components. Proper load distribution is essential for maintaining ride quality, handling precision, and long-term durability.

When to Replace
•  During shock absorber or suspension overhaul
•  Damaged, bent, or corroded mounting hardware
•  Suspension noise or movement from the strut assembly
•  Following accident or suspension impact damage
•  When replacing associated suspension mounting components

Front Shock absorber compensation ring.
A genuine Porsche compensation ring (shim/spacer ring) for the front shock absorber/strut assembly. It provides the correct spacing and seating interface within the front strut/shock assembly, helping components locate properly and clamp securely. This supports correct assembly stack height and helps prevent looseness, misalignment, or unwanted movement.

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
