Supertech 21x12x44.30mm Chrome Moly Wrist Pin

This Supertech wrist pin is made from chrome moly steel, a strong material often used for performance engine components. You get one wrist pin measuring 21mm in diameter, 12mm in height, and 44.30mm in length. It's designed to connect the piston to the connecting rod in your engine, allowing them to pivot smoothly as the piston moves.

Chrome moly steel offers a good balance of strength and durability for this critical engine part. This pin is a direct replacement for your original, meaning it should fit right into your existing piston and connecting rod setup without modification. It's a well-built component for rebuilding or repairing your engine's bottom end.
