Good To Know

Q: How do I know this ring set fits my piston? A: Match the 41.00mm bore and the 4100XZ part number to your piston before ordering. Ring end gap should always be checked during assembly.

Q: Can I install rings without checking end gap? A: No, ring end gap must be verified against your engine's specification before installation. Skipping this step can cause poor sealing or ring damage.

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