Piston - 1-Degree Linear Digressive

The Piston - 1-Degree Linear Digressive from Penske Racing Shocks is a precision-engineered shock absorber component designed for serious suspension tuning on high-performance vehicles. It is ideal for road racers, autocross competitors, and dedicated enthusiasts who demand repeatable, predictable damping characteristics.

This piston assembly features a 1-degree linear digressive design that allows for precise adjustment of compression and rebound rates. The digressive damping curve provides a softer response to initial shaft movement, progressively firming up as compression increases, which helps reduce harshness over bumps while maintaining body control during cornering.

This piston configuration excels on vehicles with independent double-wishbone, MacPherson strut, or multi-link suspension systems, where precise damping control is crucial for performance. Its compact design allows for compatibility with standard monotube and twin-tube shock architectures without modification.
