Good To Know

Q: Are the pistons sold individually or as a set? A: This kit includes two pistons, so it covers both cylinders for the Ski-Doo 500 F/C twin engine.

Q: Do I need to replace the bearings separately? A: No, the kit includes both wrist pin and connecting rod bearings, making it a complete top end rebuild package.

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