Product Features
Clutch Masters is proud to introduce the finest and most economical multi-plate clutch systems available for today’s high performance vehicles, the 725 and 850 Series. Clutch Masters Twin Disc systems are pure racing technology that also works well in high performance street applications. They are designed to hold tremendous horsepower and
torque ratings, while retaining a very smooth operation. By slightly increasing the clamping force of the pressure plate and adding to the square inches of usable disc area, CM Twin Discs significantly increase clamping values with only a 25-50% increase in pedal pressure depending on the application. The cover assembly is machined from billet aluminum with 25% more tensile strength than the competition’s cast unit. The flywheel is machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Each aluminum flywheel includes a replaceable heat shield. Steel flywheels are also available on select applications. Clutch Masters Twin Disc
