Good To Know

Q: Does this piston kit include all necessary components? A: Yes, it includes the piston, rings, and wrist pin. You will need to reuse your existing cylinder if it can be bored to .060 over.

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