About This Product
Securing your primary drive is critical for power delivery, and this compensating sprocket shaft nut from Bender Cycle is built for the task. It is designed specifically for 1970 to 1990 Big Twin models, covering a broad range of FX, FXR, Softail, and Touring motorcycles. As a high-quality replacement for OEM 40392-70, this nut ensures the sliding cam and sprocket assembly remain properly tensioned against the spring plates. Whether you are performing a routine primary service or a full engine rebuild, using a fresh, high-spec nut is vital for preventing unwanted vibration and ensuring the longevity of your compensating sprocket assembly.
