Specs At A Glance

Good To Know

Q: Does an overbore piston require cylinder machining? A: Yes, a 0.100 overbore piston needs the cylinder bored and honed to match before assembly, so measure and machine first. A: Confirm the finish bore matches piston-to-wall clearance specs for your build.

Q: Is this set enough to rebuild the whole engine? A: It covers the piston, crankshaft, and gaskets in the title, but bearings, seals, and other wear parts may still need replacing. A: Inspect every internal component during teardown.

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