Specs At A Glance

Good To Know

Q: Do I need to check ring end gap before installing these? A: Yes, always check ring end gap in the cylinder bore before assembly, since gap can vary with cylinder wear. Filing to spec protects against ring damage on startup.

Q: Can I install these rings without honing the cylinder? A: A light hone helps new rings seat against the cylinder wall. Skipping it on a glazed or worn bore can prevent proper break-in.

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