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. These pistons are the perfect option for someone building a mild to moderate performance engine on a sportsman budget. As with all JE Pistons products, SRP pistons are made 100% in the USA.

  • Forged in the USA using 4032 aluminum, yielding tensile strength and minimal thermal expansion
  • Dedicated forging helps optimize strength and weight throughout the piston design
  • Perfect for street/strip applications
  • Forced pin oiling for improved pin lubrication
  • Made 100% in the USA
