Product Overview

Clutch Masters is proud to introduce the finest and most economical multi-plate clutch systems available for today's high performance vehicles, the 850 Series. Clutch Masters Twin Disc systems are pure racing technology that also works well in high performance street applications that will be used on the street on rare occasions. They are designed to hold tremendous horsepower and torque ratings, while being reasonable to operate on the track.

By 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 an average of 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.

The 850 series is a larger diameter assembly, which is designed for high horsepower applications. The 850 Series has a higher holding capacity, less clutch chatter, and a smoother engagement compared to the 725 Series. The 850 series Twin disc will accept one sprung disc creating a slightly smoother engagement compared to two rigid discs
