SRP forged pistons are born from the rich racing experience of JE Pistons, the Sportsman Racing Products (SRP) piston line proudly bridges the gap between high-quality forged piston performance and affordability. Forged from strong, 4032 aluminum alloy material, SRP pistons are designed and manufactured to reduce machining costs without sacrificing strength or performance characteristics. SRP Pistons are the perfect option for someone building a mild to moderate performance engine on a sportsman budget. SRP pistons are made 100% in the USA. Available for GM Big Block Chevy Engines. Pistons include

• Designed specifically for GM Big Block Chevy Engines. to provide optimized performance durability
• Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
• Forged in the USA using 4032 aluminum, yielding tensile strength and minimal thermal expansion, SRP Pistons are designed and manufactured to reduce machining costs without sacrificing strength or performance characteristics.
• Includes high-quality wrist pins, forced wrist pin oiling and locks
• Made 100% in the USA
• Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
• Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
• Vertical Gas Ports: Machined gas ports channel combustion pressure behind the top ring for improved cylinder sealing and reduced blow-by under high load. Common in drag racing applications where maximum ring seal is critical.
