ACT Clutch, Advanced Clutch Technology, clutch kits

Advanced Clutch Technology offers a variety of complete clutch kits. You may also purchase individual clutch components. ACT clutch kits include the pressure plate, disc, release bearing, and ( and in most cases) pilot bearing and alignment tool.

Heavy Duty Pressure Plates

Great holding power, better 60ft & 1/4 mile times, and long life are all benefits that come with these plates. What makes ACT pressure plates the highest standard of the industry? First, they start off with new units. They do not offer rebuilds (except for special circumstances or warranty work). Second, they increase the pressure the right way: by changing the diaphragm. Their diaphragms are specially heat treated through an exclusive 3 stage process and then hardened on the release bearing contact area to reduce wear. Third, they make sure that the pressure curve and release travel of the unit is in the right working range. Forth, they use proven assembly procedures that insures consistency and precision. Finally, they accurately balance and test every unit they produce. No guesswork, no hype, only proven engineering and calculated results.

Xtreme Pressure Plates

The maximum holding power available! ACT solution: apply more diaphragm pressure. With a less aggressive street disc, this makes a great combination for high HP street cars that prefer smooth engagement. For racing, combine ACT Xtreme Pressure Plate with our Xtreme Disc for the ultimate in torque capacity and durability. What makes these units so unique is a radical increase in pressure without altering the proper geometry or stacking of diaphragms. The result is maximum holding pressure and long life, while maintaining good release clearance for fast, clean shifting. This can only be done with a specially engineered diaphragm. On some units, they actually include gusseting the cover to reduce flex caused by the the high pressure. These are made with the same high standard as their heavy duty pressure plates. You will find these on many of the fastest cars on the track. How do they feel? A little stiff, but smooth! Xtreme Pressure Plates can be identified throughout the application chart when the pressure plate number is followed by a suffix "X".

Street Discs

Organic, spring center replacement disc designed for smooth engagement, quiet operation and improved durability. ACT clutches offers the best brands for the application. Street discs can be used with moderate to heavy duty applications including racing depending on torque output and heat. View our application chart for more information on torque capacity. When a special Performance Organic ACT disc is available the suffix "S" will appear in the disc part number. These discs use special performance linings that are designed to withstand high heat and high RPM. When the suffix "M" appears, the disc has been modified by reducing the marcel enabling quicker action. With all the hype about different lining materials available they still contend that nothing can beat a good quality organic disc for street use. A good example of this is the Eclipse/Talon AWD Turbo. This application can be especially hard on clutches because of all wheel drive, the heavy weight of the car, and limited clutch size. Yet because of the durability of the ACT Performance Organic Street Disc, many of the fastest Eclipse/Talons owners enjoy smooth engagement, 11 second and even 10 second time slips. This same performance lining is available for several applications where there is a particular need. It takes a lot of abuse and yet engages smoothly.

Copper Ceramic Race Discs (Xtreme Discs)

Available in 4 or 6 pad design. These pads (pucks, buttons) are highly durable and resistant to heat. They actually perform better when hot! The copper ceramic material holds approximately 28% more torque than an organic lining. Copper ceramic discs engage fairly harsh and are not normally recommended for street use. The high copper content of the material helps to absorb heat and reduce the temperature of the mating parts. Shifting is quick and sure due to the lightweight rigid design. No worries about broken center sections or springs. 6 pad discs are recommended for larger sizes to absorb more heat and for smoother engagement than the 4 pad disc. 4 pad discs engage harsher and shift faster. They are well suited for smaller disc sizes from smaller engines. We can provide any size 4 pad disc up to 240mm or 6 pad disc up to 250mm with the spline sizes listed below.
