Specs At A Glance

Good To Know

Q: Does this kit include everything for a top end rebuild? A: It pairs a .040 oversize piston with a gasket set, so you get the piston and the seals needed for the top end. Confirm any additional bearings or clips required for your specific rebuild.

Q: Why is the piston .040 oversize? A: An oversize piston matches a cylinder that has been bored to clean up wear or damage. The bore must be machined to the matching size 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.
