21. Hydraulic Shock Absorber Damper Piston

A shock absorber damper piston, the core hydraulic metering component within a high-performance suspension system. + Through-holes engineered to act as flow ports for hydraulic damper fluid during suspension compression and rebound strokes. + The central bore is tightly toleranced to press-fit or securely slide onto the main shock shaft, ensuring absolute concentricity and preventing internal fluid bypass.
