Description
The Clutch Masters FX850 is an 8.5” (216mm) Twin Disc clutch 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 work 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. The billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing on machining the strongest cover possible while maintaining minimal weight, we are basically able to eliminate any flex in the cover. The billet covers see only .003” of flex where as 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 being 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 the covers also results in greater clamping force over the same amount of area vs. a cast or stamped cover. This means these twin discs are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized.
