The Clutch Masters FX850 is an 8.5” (216mm) Twin Disc Clutch that is the ultimate in twin disk performance for engines/transmissions with smaller bell-housings. Clutch Masters FX850 Twin Disc systems are pure racing technology that also works well in high-performance street applications. The FX850 is designed to hold tremendous horsepower and torque while maintaining reasonable peddle pressure to operate on the track. By increasing the clamping force of the pressure plate and adding to the square inches of usable disc area, Clutch Master FX850 Twin Discs significantly increase clamping rates with an average of 50% increase in pedal pressure depending on the application.

The cover assembly is machined from billet aluminum and is then Type 3 hard anodized. Our billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing our ability on machining the strongest cover possible while maintaining minimal weight, we are basically able to eliminate any flex in the cover. Our billet covers see only .003” of flex whereas a cast or stamped unit can see as much as .030” of flex. By eliminating this flex in the cover, the driver is able to operate the clutch much more consistently and confidently. All the movement is applied to the diaphragm of the clutch from the throwout bearing is used solely to engage and disengage the clutch and isn’t wasted by the cover flexing first. The strength of our covers also results in greater clamping force over the same amount of area vs. a cast or stamped cover. This means our twin discs are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized.

Flywheels are made for each specific application in either aluminum or steel. Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA, and NASA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert. Steel flywheels are machined from 1045 billet cores and are then black oxide treated for rust prevention.
