Good To Know

Q: What does .040 over mean for my Ski-Doo Safari L or LE 377? A: It means the piston is sized for a cylinder bored .040 inch larger than the original bore, so the cylinder must be machined to match before installation.

Q: Are rings and wrist pins included? A: This listing covers the piston pair itself, so check your rebuild kit for matching rings, pins, and clips before you start assembly.

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