Good To Know

Q: What does a .040 oversize piston kit mean? A: It means the piston is sized to fit a cylinder bored 0.040 inches over stock, which is used to clean up wear or scoring. The cylinder must be machined to match before installation.

Q: Is this kit a direct replacement for a stock piston? A: No, it is an oversize kit, so the cylinder must be bored to the matching .040 size first. Check your engine's current bore and wear before ordering.

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