Good To Know

Q: Are these piston kits compatible with aftermarket cylinders? A: These are designed for standard bore cylinders; if your cylinders have been bored oversize, you will need oversized pistons.

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