Clutch Masters single disc clutch kits are true high performance clutch systems which are technologically superior to anything currently on the market. By re-engineering the leverage or fulcrum point on the pressure plate through our Hi-Leveragetm technique, we have been able to increase clamping power, often without changing pedal pressure. Our Hi-Leveragetm technology allows us to move the pressure plate leverage ring closer to the pivot point. Doing this has allowed us to solve the clamping vs. pedal pressure problem in a unique way. By moving the pressure ring pivot point, our Hi-Leveragetm Pressure Plates take mechanical advantage of the leverage principle. By moving the leverage ring closer to the pivot point as well as re-arching and precisely heat treating the clutch diaphragm, the pressure applied to the clutch disc is increased significantly without unnecessarily increasing pedal pressure, as is typically the case with other aftermarket clutch options. Moving the pivot point takes several extra steps to accomplish when manufacturing our clutches in order for them to work flawlessly with OEM stamped covers and is something we’ve perfected through our over 40 years of industry expertise.

In addition to our ability to increase clamping pressure without increasing pedal pressure, there are some other key advantages realized when using our Hi-Leverage technology. One serious problem associated with increased pedal pressure is it increases the chances of damaging the crank thrust bearing, inherently leading to crank-walk. Increased pedal pressure can put additional strain and fatigue on clutch linkages, throw out bearings and hydraulic systems causing them to fail prematurely.

All stages come as a complete kit including disc, pressure plate, throwout bearing, pilot bearing (when applicable), and alignment tool. (Individual components available upon request)

70% Increased Holding Capacity

The FX100 System uses the Power Plus I Heavy-Duty Pressure Plate with a steel backed organic friction material disc. This clutch is engineered for street driven vehicles and is specifically designed for extended wear and additional clamping force for the enthusiast who has added minor bolt-ons such as an exhaust and or intake system, up to 50hp NO2, or other non-forced induction external bolt ons. It features only slightly increased pedal pressure over factory, longer life than stock, and normal clutch feel during engagement and disengagement for a very smooth operation.

*Organic/ Kevlar/ Fiber-Tough Clutch kits are expected and tend to have a higher life expectancy than OEM, however not guaranteed. Improper Installation, Driving style, performance upgrades, Break in procedure and light weight flywheels will effect and have a role in determining the life expectancy of the clutch kit.

70% Increased Holding Capacity

The FX200 System uses the Power Plus I Heavy-Duty Pressure Plate with a steel backed Kevlar friction material disc. This clutch is designed for the street enthusiast or weekend racer. The FX200 offers similar torque holding capacity to the FX100, however, it’s life expectancy is increased 2-3 times with the Kevlar disc. This clutch is a great option if you drive your car aggressively but only have simple bolt-ons. Our Kevlar friction material is non-abrasive and doesn’t score the mating surfaces. It features only slightly increased pedal pressure, significantly longer life than stock, and normal clutch feel during engagement and disengagement for the smoothest operation of any stage we offer.

110% Increased Holding Capacity

The FX250 System uses the Power Plus I Heavy-Duty Pressure Plate and utilizes a combination of our Fiber Tough friction material on the side of the disc contacting the pressure plate, and steel backed organic friction material on the flywheel side of the disc. This clutch is designed for the street enthusiast or weekend racer who plans to abuse their vehicle on an occasional basis and has a very spirited driving style. The FX250 clutch system has a higher holding capacity than a traditional full faced kevlar without compromising the street friendly characteristics exhibited in the FX100 and FX200 series.

110% Increased Holding Capacity - STREET

The FX300 System uses the Power Plus I Heavy-Duty Pressure Plate and utilizes a steel backed segmented Kevlar disc. This clutch is designed for the ultimate street enthusiast running a normally aspirated car that has been highly tuned with cylinder head work such as cams, or with a medium-boost turbo or supercharger setup, or up to 100hp NO2. The FX300 has proven to be one of our most successful single disc clutch options over the years. By combining the use of Kevlar friction material in a segmented format, we create more pounds per square inch, allowing more torque holding capacity while still delivering exceptional life. Our Kevlar material is non-abrasive and doesn’t score the mating surfaces. The FX300 features only slightly increased pedal pressure, long life, and positive engagement. The FX300 is recommended for the street and not for track use. There is a minimum of 500 mile break in period required with this clutch.

110% Increase in Holding Capacity - STREET/RACE

The FX350 System uses the Power Plus I, Hi-Levarage, Heavy-Duty Pressure Plate utilizing our Fiber-Tough friction material. This clutch has a slightly increased holding capacity then the FX300 but will have a slightly more aggressive engagement and will produce some chatter. Similar to the FX300 this clutch is designed for the serious street enthusiast who also might spend a weekend and the track and is running a normally aspirated car that has been highly tuned with cylinder head work such as cams, or with a medium-boost turbo or supercharger setup, or up to 100hp NO2. For years enthusiasts have had to compromise durability for longevity for drivability and vice versa, however with our Fiber-Tough material we have closed the gap between these two tradeoffs. *

The FX400 System uses the Power Plus I, Hi-Levarage, Heavy-Duty Pressure Plate with a custom and extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 6 or 8 ceramic puck configuration. The 6-puck being the more aggressive setup and 8-puck being the less aggressive. The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation.

The FX400/HDCL (8-puck) ceramic full face disc design creates a quick and rapid engagement and maintains minimal chatter due to the marcel cushion between the disc linings. This disc is designed for street driven vehicles.

The FX400/HDC6 (6-Puck) ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that may not be ideal for street driven vehicles. *Warning* Due to the solid (no Marcel) friction rivet design, the FX400 6 disc engages very quickly and may chatter slightly in first and reverse. To help alleviate this problem, we only use premium ceramic friction material.
