Good To Know

Q: Does this ring set fit more than one piston? A: This listing is for one ring set, so order the quantity that matches the number of pistons you are rebuilding. Confirm the 65.50mm bore matches your piston before ordering.

Q: Should rings be gapped before installation? A: Piston rings typically need the end gap checked and set to the engine builder's specification before assembly. Follow the ring manufacturer's guidance for your application.

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