Clutch Masters is proud to present our FX850 Strapped Twin Disc Clutch Kit. We developed the FX850 Strapped out of necessity to bridge the gap between a single disc clutch that is easy to drive on the street and our original FX850 Twin Disc. While our original 850 Twin Disc is treatable, it was never designed with extended street use in mind. That is where the 850 Strapped is different. Utilizing drive straps to isolate the pressure plate and the mid-plate between the two discs, we are able to virtually eliminate all chatter and allow for a much smoother engagement.

This similar methodology has been proven to work incredibly well in our FX1000 and FX1200 Twin Disc kits with users reporting that their cars or trucks are able to be driven with ease on the street yet take a beating on the track, all while maintaining very manageable peddle pressure. With one sprung ceramic disc and one rigid ceramic disc utilizing the highest quality ceramic material, you can be confident that your clutch won't be slipping.

Like the rest of our twin disc covers, the 850 STRAPPED 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 essentially 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. While both of those numbers may seem small, in the reality of a clutch and the minimal amount of movement they have to begin with to engage and disengage, by drastically reducing 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 protections from drivetrain shock by using a dampened clutch disc.

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.
