Good To Know

Q: How do I know this ring set fits my piston? A: Match the 73.00mm bore size and the listed part number to your piston before ordering. Ring sets are made for a specific piston design, so verifying the number avoids a mismatch.

Q: Should I check ring end gap after installation? A: Yes, ring end gap should always be measured and set to the piston maker's specification during assembly. Correct gap helps sealing and prevents ring butting as the engine heats up.

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