Organic, spring center replacement Specialist disc designed for smooth engagement, quiet operation and improved durability. We offer the best brands and type for the application. Some OE Street Clutch discs can be used with moderate to heavy duty applications including racing depending on torque output and heat. When a Performance OrganicOE 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 we still contend that nothing can beat a good quality full face organic disc for street use. This same ACT Clutch performance lining is available for several applications where there is a particular need.These clutch discs take a lot of abuse and yet engage smoothly.

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

The maximum holding power available! How to : Our 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 our Xtreme Pressure Plate with our race 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 clutch units, like the one shown above, we actually include gusseting the cover to reduce flex caused by the the high pressure. These clutches are made with the same high standard as our 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".
