With more friction area, as well as a larger centerline diameter, the new S&S clutch is able to handle over 150 horsepower with clutch lever effort that is slightly less than that of a stock Harley-Davidson clutch. For competition applications, a stronger pressure plate spring is available that will increase the power handling capacity to over 200 horsepower. The S&S high-performance clutch fits ’91-’05 models and features an early style 66-tooth ring gear.
