Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: Match the 39.50mm bore size and the 1555CS part number to your piston and cylinder spec before ordering. Ring thickness and profile must match the piston groove for correct sealing.

Q: Can I install this ring set without checking end gap? A: No, always check ring end gap and side clearance during assembly. Proper gapping prevents ring butt and ensures the rings seat correctly against the cylinder wall.

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