CP Pistons 9310 Steel Chamfered Wrist Pin (Per Piston)
The CP Pistons is a premium 9310 steel chamfered wrist pin designed for high-performance and racing piston applications. Manufactured from high-strength 9310 nickel-chromium steel alloy, these pins offer superior tensile strength, fatigue resistance, and durability under extreme loads and high RPM.
The chamfered ends reduce stress concentrations and improve wrist pin retention while allowing for smoother operation and reduced wear on the piston and connecting rod. Sold individually (per piston), these pins are a critical upgrade for serious engine builds where standard pins may fail under boosted, high-horsepower, or high-RPM conditions. Ideal for use with CP Pistons or other forged piston kits requiring a robust 0.927″ diameter pin.
