Front Track Drive Sprocket for Ski-Doo Alpine 440

This front track drive sprocket is a direct-fit replacement for Ski-Doo Alpine 440 snowmobiles produced between 1971 and 1977, engineered to transfer engine power to the track drive shaft.

Overview

This front track drive sprocket is made for Ski-Doo Alpine 440 models from 1971 through 1977 and serves as the drive connection between the shaft and the track.

Good To Know

Q: How do I know if my front track drive sprocket needs replacing? A: Common signs include visible tooth wear, cracking, track slippage under load, or a skipping sensation while riding. Inspecting the sprocket whenever the track is serviced helps catch these issues early.

Q: Does this sprocket fit every Ski-Doo Alpine 440? A: It is intended for Alpine 440 models built between 1971 and 1977, but drive shaft and track configurations can vary by serial number. Confirm your machine's year and driveline setup before ordering.

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