About This Product
When your clutch starts slipping under load, a tired diaphragm spring is often the culprit. This MCS replacement clutch spring is a standard-duty 1.8mm version, designed to restore the factory-spec clamping force to your clutch pack. It is a direct replacement for OEM 37971-90 and 37871-90, fitting 1990 to 1997 Big Twin models. Whether you are doing a routine plate change or a full primary overhaul, installing a fresh spring ensures consistent lever feel and prevents premature wear on your friction discs. It is a simple, cost-effective way to maintain the performance of your Evolution-era drivetrain without moving to an overly stiff aftermarket setup that makes the lever hard to pull in traffic.
Manufacturer part number: 580214.
