Good To Know

Q: How do I confirm this ring set matches my engine? A: Check that your piston and cylinder bore are the 66.50mm size listed here and that your Wiseco piston specifies the 2618XA ring set. Comparing the part number to your piston or service manual avoids ordering the wrong rings.

Q: Does this cover more than one piston? A: No, this listing is for one ring set intended for a single piston. Adjust the quantity to match the number of pistons being rebuilt.

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