Specs At A Glance

Good To Know

Q: Can this piston kit be installed without machining the cylinder? A: This .020 over bore piston kit requires the cylinder to be bored and honed to the correct clearance; it is not a drop-in fit for stock cylinder dimensions.

Q: Does the kit include the piston pin clips? A: The kit includes the wrist pin but not the retaining clips; be sure to use new clips during installation to prevent pin walk.

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