Good To Know

Q: How do I know this ring set fits my piston? A: Match the 66.00mm bore size and the 2598XD part number to your piston to confirm the correct ring set before ordering.

Q: Can I install this without checking ring end gap? A: Always measure ring end gap during assembly, since gap must be set to your cylinder and application for proper sealing.

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