About This Product
This rear brake cam from MCS is designed for the mechanical drum brakes found on early Harley-Davidson Big Twins. It acts as the operating cam that pushes the brake shoes against the drum when the pedal is depressed. This specific cam fits 1937 to 1957 Big Twin models with 61, 74, or 80 cubic inch engines. If your original cam is notched or worn, you will lose that crisp brake feel and stopping power. Replacing it with this high-quality component, which matches OEM 41671-37, will restore the mechanical advantage needed for reliable rear braking. It is a must-have for anyone keeping a vintage Panhead or Knucklehead on the road.
Manufacturer part number: 901745.
