About This Product
This 22-tooth compensating sprocket is a replacement part for 1970 to 1984 Harley-Davidson Big Twin, FX, FXR, and Touring models. It replaces OEM 40280-70 and is an integral part of the primary chain drive system. Designed for the 1970 to 2006 style compensator assemblies, it works in conjunction with spring plates to absorb engine vibration and torque spikes. A worn sprocket can lead to excessive primary noise and potential damage to the sprocket shaft. This Zodiac sprocket ensures that your classic Big Twin maintains a smooth transfer of power, providing the reliability needed for both stock restorations and daily riders.
