Description JE 139633S Piston Single SRP (4.040 in. Bore, 1.560 in. CH, -24.00 CC) for CHEVROLET Small Block Engine

Born from the racing experience of JE Pistons, the Sportsman Racing Products (SRP) piston line bridges the gap between high-quality forged piston performance and affordability.

Forged from strong 4032 aluminum alloy, SRP pistons are designed and manufactured to reduce machining costs without sacrificing strength or performance. They are suitable for mild to moderate performance engines on a sportsman budget.

• Forged in the USA from 4032 aluminum for tensile strength and minimal thermal expansion
• Dedicated forging optimizes strength and weight throughout the piston design
• Suitable for street/strip applications
• Forced pin oiling improves pin lubrication
