Shock absorber concave washer, lower
This Shock Absorber Concave Washer is an OE-style suspension mounting washer designed for Porsche front suspension systems equipped with advanced chassis control features. The concave washer supports and stabilises the front shock absorber mounting assembly by evenly distributing clamping force across suspension components. It helps maintain proper suspension geometry, mounting security, and stable damper operation.

This washer is specifically used on Porsche vehicles equipped with advanced suspension technologies including Front Axle Lift Function (Option Code 474) or Controlled Suspension System (Option Code 2UH). These systems place additional dynamic loads on the suspension assembly, making correct load distribution and component positioning essential for maintaining ride quality, handling precision, and long-term suspension durability.

Ideal for suspension rebuilds, shock absorber replacement, accident repair, or preventative maintenance, this component helps restore factory suspension integrity and reliable chassis performance.

Function
•  Distributes suspension load evenly across mounting points
•  Supports correct positioning of shock absorber assembly
•  Helps maintain proper front suspension geometry
•  Reduces stress on suspension mounting surfaces
•  Supports stable operation of controlled suspension systems

Suspension mounting hardware is subjected to constant dynamic load, vibration, and road impact. A damaged, bent, or corroded concave washer can affect shock absorber alignment, unevenly distribute suspension loads, and potentially lead to premature wear of mounting components. Replacing worn or damaged washers helps maintain suspension stability, ride comfort, and chassis integrity.

When to replace
•  During shock absorber or suspension servicing
•  Bent, cracked, or corroded washer surfaces
•  Suspension noise or movement around strut assembly
•  After suspension impact or accident damage
•  During front axle lift or PASM component replacement
