A clutch, simply put, is a friction device that disengages and engages the engine from the transmission to allow for transition from motionless to movement and for gear changes. As power output of engines begin to increase and demands on clutches become greater, the holding and clamping capacity of a clutch also must increase. This is where Clutch Masters' innovative engineering comes into play. Clutch Masters has been a premier manufacturer of high quality performance clutches for nearly 20 years.
