Specs At A Glance

Good To Know

Q: Do these piston kits come with gaskets? A: No, these are piston-only kits; gaskets are not included and must be purchased separately for a complete rebuild.

Q: Are these pistons compatible with standard bore cylinders after honing? A: These .020 over bore pistons require the cylinder to be bored to the corresponding oversize; standard bores must be machined 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.
