Good To Know

Q: Does this kit include a piston? A: No, this is a gasket and ring kit; a separate .040 over bore piston is required for the rebuild.

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