Good To Know

Q: How do I confirm this ring set fits my piston? A: Check that the piston requires a 66.50mm bore and cross-reference the 2618CD number before ordering. Ring end gaps should be verified during assembly.

Q: Do these rings need cylinder work first? A: They are sized for a 66.50mm bore, so the cylinder should already be finished to that dimension. Check ring end gap and piston clearance when installing.

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