Good To Know

Q: How do I know this sprocket fits my Blizzard? A: It is listed for 1970-1971 Blizzard models with 336, 339, 340, or 397 engines. Confirm your sled's year, engine size, and drive shaft configuration before ordering.

Q: Can I replace just one sprocket? A: A single sprocket can be replaced if the others are still in good shape. Inspect the entire front drive assembly and the track lugs at the same time for even wear.

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