Good To Know
Q: Is this piston kit compatible with aftermarket cylinders? A: This piston kit is designed for standard bore cylinders; if your cylinder has been overbored, you will need a corresponding oversized piston.
Q: Does this kit include the wrist pin bearing? A: The kit includes the piston, rings, and wrist pin but does not include the wrist pin bearing or circlips, so verify your existing components before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
