Description
The Bilstein Piston 8 ID 46 Digressive is engineered for serious suspension tuning, delivering progressive damping control that responds intelligently to both low-speed and high-speed compression events. If you’re rebuilding a high-performance shock or replacing a worn piston in your Bilstein unit, this OEM-quality component ensures your suspension maintains the precise valving characteristics necessary for consistent on-track or street performance. Choosing the correct piston specification is critical—this digressive design won’t work as a drop-in replacement for linear pistons, so verify your shock’s requirements before ordering.
