Drop-in Replacement: Designed as a drop-in replacement for damaged, belt-eating Powerdyne sprockets. If yours is worn or has sharp edges, replace it now and enjoy greater reliability from your Powerdyne!
Performance Upgrade: Our sprocket and input shaft assembly is lighter than stock, which means less rotating mass and less stress on the internal drive belt. Racers love this new sprocket!
Installation: Installs as before, during your next Powerdyne rebuild. No changes necessary.
