Specs At A Glance

Good To Know

Q: Will this sprocket fit my Alpine's drive axle? A: It is intended for the front drive position on Alpine 250, 250S, 300, 370, and 370E models from 1964 to 1969. Confirm your model year and axle configuration before ordering.

Q: Do I need to replace both sprockets at once? A: Replacing drive sprockets in pairs helps keep the track running evenly. Inspect the opposite side for matching wear before you install.

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