Performance Forged Pistons
Speedmaster Flat-Top Forged Pistons are designed with a structurally-sound reduced piston-to-wall clearance that increases power (900+ hp), improves sealing and reduces cylinder wear. These 4032 aluminum alloy pistons operate quieter, are up to 20% lighter than traditional forged pistons, and ideal for street performance, endurance racing, and drag racing applications.
