The FX1200 Twin Disc Series is 12" (305mm) diameter assembly, which is designed for incredibly high torque output applications found in diesel trucks. The 1200 Series utilizes a strap driven plate design which allows for smooth engagement and minimal clutch chatter while still being able to withstand hard launches and heavy trailer pulling. The average weight of the entire system has been engineered to be roughly 10% lighter than the factory clutch in order to maintain minimal gear chatter in your NV4500, NV5600 or G56 transmission. The 1200 series Twin disc will accept one sprung disc creating a smoother engagement compared to two rigid discs.

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 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.

Steel flywheels are precision machined from 1045 billet cores and are then black oxide treated for rust prevention. Aluminum flywheels are available for diesel applications as well and are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IHRA, SCCA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert.
