About This Product
When you are diving into the primary on an older Big Twin, you want hardware you can trust. This Genuine Zodiac compensating sprocket shaft nut is a high-quality replacement for the factory original, specifically designed to fit 1970–1990 FX, FXR, Softail, and Touring models. It is a critical component of the primary chain drive system, ensuring the compensating sprocket assembly stays securely fastened to the crankshaft. Replacing this nut during a primary service is a smart move to maintain the integrity of your drivetrain and prevent loosening over time. This part is a direct replacement for OEM 40392-70 and is built to the same exacting standards as the rest of Zodiac’s compensating sprocket components.
