Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Match the 76.70mm bore and the 2658KD part number to the piston already in the engine before buying. Ring sets are bore and piston specific, so a nearby size will not seal correctly.

Q: Do I need to check ring end gap after install? A: Yes, ring end gap should be measured and filed to the piston maker's spec before final assembly. Skipping that step risks broken rings or poor sealing once 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.
