About This Product
This 66-tooth rear wheel pulley is a high-quality, hard-anodized reproduction designed for Softail models using a 20mm drive belt. Finished in a clean black, it serves as a direct replacement for OEM 37710-07. It fits 2007 to 2011 Fat Boy, Fat Boy Lo, Cross Bones, Softail Standard, and Night Train or Softail Custom models. The hard-anodized finish is crucial for longevity, protecting the teeth from the abrasive road grit that can wear down softer pulleys. This MCS pulley ensures your final drive remains quiet and efficient while maintaining the stock gearing of your 200mm-tire Softail. It is a dependable choice for any mechanic looking to restore the drivetrain of a mid-2000s Big Twin to its original performance standards.
Manufacturer part number: 520278.
