About This Product
MCS clutch release disc. This stock-style disc replaces OEM 37901-84A. It fits late 1984 through 1989 Big Twin models. It sits directly below the clutch spring and provides the correct seat for the diaphragm. A worn or cracked disc causes uneven spring load and a dragging clutch. Fit a fresh one every time you open the primary. It is cheap insurance against a sticky clutch.
Manufacturer part number: 580218.
