Clutch Masters 850 Series Race Twin Disc Clutch Kit N54

Clutch Masters Twin Disc Clutch Kit: 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.


*725 SERIES* – (7.25” Twin Disc)
The 725 series is a smaller diameter assembly, which creates less rotating mass and offering quicker, and smoother shifting with much better throttle response. 

*850 SERIES* – (8.50” Twin Disc)
The 850 series is a larger diameter assembly, which is designed for high horsepower applications that require smooth engagement, quiet operation and high clamp load.


*All systems include:*
* Cover Assembly with attached Diaphragm
* Pressure Plate Ring
* Two Discs
* One Mid Plate
* Billet Aluminum Flywheel
* Release Bearing
* Pilot Bearing (when applicable)
* Pressure Plate Bolts

Today, thanks to Clutch Masters, increased holding pressure does not necessarily mean increased pedal pressure and the problems that can accompany it. By re-engineering the leverage or fulcrum point on the pressure plate through their Hi-Leverage technique, Clutch Masters has increased clamping power, often without changing pedal pressure.

Excessively increased pedal pressure, as found in many of today's traditional high performance clutches, places an unsafe amount of pressure on the delicate crankshaft thrust bearing found in most of today's sport compact automobiles. Placing undue stress on the thrust bearing typically causes the bearing to wear prematurely or fail altogether. This failure can lead to catastrophic internal engine damage.

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. For street applications a smooth transition of power is essential while still being able to transfer all the power of the engine to the transmission. As power output of engines increase and demands on clutches become greater - for example high performance street or racing cars - the holding and clamping capacity of a clutch also must increase. This is where Clutch Masters' innovative engineering comes into play.
