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. Our billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing our ability on machining the trongest 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 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 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.

Alternatively our 850 Twin Disc can be upgraded to our DLX series. With the DLX series we have engineered a way for both discs to inherently be dampened. By directly connecting a rigid disc to the disc with the sprung hub both discs are able to transfer any shock load through to the dampened hub. Not only does this setup work incredibly well for a daily driven car making high horsepower it also is great for a race car that wants that extra protection from drivetrain shock by using a dampened clutch disc.

Every Clutch Masters flywheel is proudly designed and manufactured in the USA. Flywheels are first designed in CAD and are then precision CNC machined in house in one of or Haas CNC lathes out of 6061 aluminum billet cores. After machining the flywheel is zero balanced to ensure it is evenly weighted on all sides and spins 100% true. Each aluminum flywheel is Type 3 Hard Anodized for the ultimate in durability and protection of the aluminum. The flywheel is then assembled by a Clutch Master Craftsman, double checked for imperfections and tolerances, and is then ready to be paired with your OEM clutch kit or one of our FX100-FX500 single disc clutch kits or twin disc options.
