Good To Know

Q: How do I confirm this ring set fits my piston? A: Match the 48.75mm bore size and the 1920CS part number to your piston specification before ordering. Ring sets are bore-specific and will not seal correctly if the size is wrong.

Q: Should I replace the rings every time I rebuild the top end? A: Yes, new rings are normally fitted whenever the piston is replaced or the cylinder is honed. Reusing old rings can lead to poor compression and oil consumption.

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