Specs At A Glance

Good To Know

Q: How do I confirm these rings fit my piston? A: Check the 54.75mm bore size and part number 2185CS against your piston before ordering. Rings are matched to a specific piston, so both details should line up.

Q: Are new rings enough on a worn cylinder? A: Rings work best when the cylinder bore is within spec and properly honed. Measure bore wear and ring end gap before assembly to avoid poor sealing.

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