Piston HF 1-Deg/2-Deg OR-2028-B

The Piston HF 1-Deg/2-Deg OR-2028-B from Penske Racing Shocks is a precision shock absorber component engineered for high-performance suspension tuning on track-focused vehicles and competition platforms. This piston assembly is designed for builders and mechanics who demand granular control over damping characteristics, allowing fine adjustment of shock behavior across compression and rebound circuits. Whether you're dialing in a road course setup, preparing for autocross competition, or optimizing a street performance suspension, this component delivers the adjustability serious enthusiasts require.

The 1-degree and 2-degree metering options inherent in this piston design allow you to fine-tune the flow characteristics that govern how oil passes through damping circuits during suspension compression and extension cycles. By selecting between these angle configurations, you control the rate at which the shock responds to vertical load inputs—critical for balancing grip, stability, and responsiveness. Penske Racing Shocks' engineering ensures minimal hysteresis and consistent performance across temperature ranges, essential for repeatable lap times and predictable vehicle behavior under sustained cornering loads. The compact 2.65 x 1.4 x 3.6-inch form factor integrates seamlessly into most modern shock bodies rated for Penske internals.

This piston assembly is ideal for motorsport competitors, dedicated track day drivers, and suspension technicians building custom setups where off-the-shelf shock valving falls short. Installation requires proper shock disassembly and familiarity with internal shock architecture; most builders pair this with quality shock oil and appropriate spring rates matched to vehicle weight and intended use. Compatibility is broad across Penske Racing Shocks platforms and compatible third-party shock bodies that accept OR-2028-B internals. For best results, pair with a complete suspension setup strategy and validate tuning through on-track testing or dyno simulation.
