Supertech Subaru EJ20 23mm H13 Tool Steel Alloy Wrist Pin

This is a Supertech H13 tool steel alloy wrist pin for Subaru EJ20 engines. It's a direct replacement for the stock pin, measuring 23mm in diameter. Using H13 tool steel means this pin is well-built for the high stresses found in performance or rebuilt EJ20 engines.

H13 tool steel is known for its toughness and resistance to wear, making it a solid choice for the critical job of connecting the piston to the connecting rod. This material helps ensure the pin can handle increased cylinder pressures and temperatures that can occur with engine modifications or during demanding use. It fits right into the factory piston and connecting rod setup for the EJ20, simplifying installation for your engine build.
