Good To Know

Q: Is this kit suitable for a complete top-end rebuild? A: Yes, it includes piston, rings, wrist pin, and clips, but you may need new cylinder head gaskets and base gaskets separately.

Q: Does size A refer to the piston diameter tolerance? A: Size A indicates the piston is manufactured at the standard specification, typically for use with a stock cylinder that has not been overbored.

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