The 850 Series Twin Disc Clutch Kits are designed for high horsepower applications that require smooth engagement, quiet operation and high clamp load.

Clutch Masters Twin Disc systems are pure racing technology that also work 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.
