Clutch Masters is proud to manufacture the finest multi-plate clutch systems available for today’s high-performance vehicles. Clutch Masters twin disc clutch systems are pure racing technology that also works in high-performance street applications that will be used on the street on rare occasions. Whatever type of car you’re driving, Clutch Masters Industries can help add clamping pressure without exaggerating the pedal pressure.

At Clutch Masters Industries, we aim to provide drivers with the best dual-disc clutch systems possible. Using our decades of experience as a clutch and parts manufacturer, we’ve created twin disc clutch parts that enhance holding power without making the pedal unnecessarily heavy. These double disc clutch systems are designed to hold tremendous horsepower and torque ratings while being reasonable 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 Masters twin discs significantly increase clamping values with an average 50% increase in pedal pressure depending on the application. The cover assembly is machined from billet aluminum that is hard anodized and offers 25% more tensile strength than the competition’s cast unit. Twin disc flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA, and NASA. Each aluminum flywheel includes a replaceable heat shield. 1045 Billet steel flywheels are also available on select applications.

725 SeriesTwin Disc Clutch Kits

Available Stages:
  • “Street and Race” (TD7S) – 1 ceramic rigid disc, and 1 fiber tuff rigid disc
  • “Race” (TD7R) – 2 ceramic rigid discs

The Clutch Masters FX725 is a 7.25" (184mm) Twin Disc clutch and is the ultimate in twin disk performance for engines/transmissions with smaller bell-housings that are focused on drag racing. Clutch Masters FX725 Twin Disc systems are developed from decades of experience in drag racing. Because of the minimal rotational mass the FX725 isn't ideal for the street but with improvements in friction material over the years we have been able to create a solution that can handle occasional street driving. The FX725 is designed to hold tremendous horsepower and torque, while maintaining reasonable peddle pressure to operate on the track.

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.

FX 725 Series

What makes our FX725 and FX850 Multi-Disc Kits truly special, and a feature unique to Clutch Masters is our QR System, or Quick Release Pressure Plate. The QR System Incorporates three spring-loaded bolts allowing the pressure plate to engage and disengage evenly and smoothly while reducing internal clutch noise/chatter by up to 50%. The QR System was developed to provide quiet and smooth operation for the street user while delivering the performance a multi-disc race clutch needs.

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.

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.

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.

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.
