Specs At A Glance

Good To Know

Q: How many rings come in this set? A: This is a piston ring set for one piston, so it includes the rings needed for a single cylinder. Confirm the count against your piston before ordering.

Q: Does ring end gap need adjustment? A: Ring end gaps should always be checked and filed to the piston maker's spec during assembly. Skipping that step can cost compression or damage the cylinder.

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