Replacement Sprocket and Shaft Assembly
for Powerdyne Supercharger

After lightweight input gear installation, the unit is a bit more peppy now! Thank you for producing top quality parts I can depend on. Tim A.

Application: Fits BD-600 BD-10 BD-11 BD-11R BD-11a BD-12 Powerdyne Superchargers, B&M, CoolCharger, and Dinan superchargers

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 shaft assembly is lighter than stock, which means less rotating mass and less stress on the internal drive belt. Racers love this new sprocket!
