Good To Know

Q: How do I know these rings match my piston? A: Match the 66.00mm bore size and the 2402CD part number to the piston you are installing. Confirm the ring groove sizing before assembly.

Q: Can I install rings without checking end gap? A: No, ring end gap should always be measured in the cylinder before final assembly. This confirms the set suits your specific bore and application.

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