About This Product
If you are experiencing clutch issues or performing a primary teardown, replacing the clutch release disc is a smart move. This MCS clutch release disc is a stock-style replacement that installs directly below the clutch spring to ensure proper engagement and release. It is built to meet original specifications and serves as a direct replacement for OEM 37912-91. This disc fits 1991 to 1997 Big Twins and a broad range of XL Sportsters from 1991 all the way up to 2022, though it excludes the XR1200 models. It is a reliable, cost-effective part for maintaining the smooth operation of your Harley-Davidson drivetrain.
Manufacturer part number: 531021.
