Good To Know

Q: Do these piston rings require any special installation tools? A: Standard ring expander tools are recommended to avoid twisting or damaging the rings during installation; follow torque specifications for the cylinder head.

Q: Can these rings be used with a stock bore piston? A: No, these rings are specifically sized for a .020 over bore cylinder; using them on a stock bore will result in incorrect ring gap and potential engine damage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
