    • Product Description

      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.

      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.

      Made by Clutch Masters, you can't go wrong.

      All stages come as a complete kit including disc, pressure plate, throwout bearing, pilot bearing (when applicable), and alignment tool. (Individual components available upon request)

      Clutch Masters Twin Disc features:
      Components can be purchased separately for economical repair.
      Positive release for ease of high RPM staging and shifting.
      Most have experienced better 4/10's times and averaged hundreds of passes without complications or repair


      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


      Choose from:

      FX600 > Bonded Organic Kevlar mix for the street
      FX700 > Compressed Ceramic Bronze for the strip

      Average weight of the entire assembly is over 50% lighter than OEM

      Clutch Masters

      Simply the Best

      High Technology Makes the Difference
      Historically, high performance clutches have been a compromise. While improving holding or clamping pressure, manufacturers nearly always increase pedal pressure to an uncomfortable point, especially for stop-and-go traffic.

      Besides drivability concerns, additional pedal pressure can adversely affect stock clutch linkage and cause premature thrust bearing wear, leading to missed shifts, damaged clutch components and even engine destruction.

      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-Leveragetm ttechnique, 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.
