The CP Pistons 9310 steel wrist pin is an upgraded piston pin offered as a direct replacement for engines needing higher-strength wrist pins. Machined from 9310 steel, it provides a durable piston-to-rod connection for rebuilds and performance builds. Use it when replacing worn pins to restore reliable valve-train operation and consistent piston retention during heavy-duty or repeated service cycles.
