ACT Clutch Kit Applications
ACT Flywheel Applications

ACT Clutch offers a variety of complete clutch kits, as every driver, engine, and application is different. You may also purchase individual clutch components. The ACT Clutch application chart will have a line for each kit available. To the right of the ACT clutch kit number, you will find individual part numbers the ACT clutch kit includes.

ACT clutch kits include the pressure plate, disc, release bearing, pilot bearing and alignment tool as indicated by the components listed to the right. The ACT Clutch application chart is designed to help you decide which level of performance and characteristics are best for your vehicle. To choose which ACT Clutch kit is right for your vehicle, read the product information below. Also review the torque capacity and increase in clamping force for each ACT clutch kit when making your decision. If you are unsure, please contact our technical staff. WE will be glad to assist you.

ACT Heavy Duty Pressure Plate

ACT Clutch Heavy Duty Pressure Plate

TOTALLY TOUGH! ACT Heavy Duty Pressure Plates provide increased torque capacity, durability, and extended clutch life. What makes ACT Pressure Plates the highest standard in the industry First, ACT manufacturing always begins with new units. ACT Pressure Plates are not rebuilt from worn out parts. Second, pressure is increased the right way. Altering the geometry alone is not enough. Instead, ACT engineers a stronger diaphragm. ACT diaphragms are heat-treated using an exclusive 3-stage process and the release bearing contact area is hardened to reduce wear. Third, ACT designs the pressure and release travel of the unit to be in the optimum working range. Finally, ACT assures consistency and precision by using proven assembly procedures. Every unit ACT produces is accurately balanced and tested.

No guesswork, no hype, only proven engineering and calculated results for every ACT Heavy Duty and Xtreme Pressure Plate. Most ACT pressure plates are also available in ductile iron, offering strength and safety for high RPM racing.


ACT Xtreme Pressure Plate

ACT Clutch Xtreme Pressure Plate

NO MERCY! ACT Xtreme Pressure Plates deliver the maximum holding power available! For high horsepower streetcars, combine this high clamp pressure plate with an ACT Street Disc to maintain smooth engagement and obtain high torque capacity. For racing, combine the ACT Xtreme Pressure Plate (most available in ductile iron) with the ACT Xtreme Race Disc for the ultimatein torque capacity, durability and quick shifting. What makes these units so unique The radical increase in clamp load developed from a single specially designed diaphragm. ACT employs several secrets (just good engineering) to maximize load and reduce flex. The result is maximum torque capacity and long life, while maintaining good release clearance for fast, clean shifting. On some units, such as the Eclipse/Talon, ACT gussets the pressure plate cover to reduce flex caused by the high pressure. ACT Xtreme Pressure Plates are made with the same high standard as ACT Heavy Duty Pressure Plates. ACT Xtreme Pressure Plates canbe found on many of the fastest cars on the track. ACT

Xtreme Pressure Plates are identified throughout the application chart when the pressure plate number is followed by a suffix "X". A double "XX" suffix indicates an ACT MaXX Xtreme Pressure Plate available for the most serious torque producers. The "XX" ACT MaXX Xtreme Pressure Plates may only be used with ACT Race discs.

Please contact the our technical staff for availability and applications. It's Xtreme to the MaXX!


ACT Copper Ceramic Race Disc (Xtreme Disc)

ACT Clutch - Copper Ceramic Race Disc (ACT Xtreme Disc)

RACE READY! Attack the track with the ACT Xtreme Race Disc. Shifting is quick and sure due to the lightweight rigid design. ACT Xtreme Race Discs are available in 4 or 6-pad solid hub design, these pads (pucks, buttons) are highly durable and resistant to heat. Why use an ACT Xtreme Race Disc The copper ceramic material holds approximately 28% more torque than an organic lining. ACT Copper Ceramic Xtreme Race Discs engage fairly harsh and are not normally recommended for street use. ACT recommends 6-pad ACT Xtreme Race Discs for larger clutch sizes to absorb more heat and for smoother engagement. The 4-pad ACT Xtreme Race Discs engage harsher, shift faster, and are well suited for smaller disc sizes from smaller engines. ACT can provide any size 4-pad disc up to 240mm or any size 6-pad disc up to 250mm with the spline sizes listed on the ACT Xtreme Disc Spline Guide. The ACT application chart lists only those ACT Xtreme Race Discs used with ACT Heavy Duty and Xtreme Pressure Plates. Consult ACT regarding applications not listed. Spline sizes marked with an asterisk (*) are special order and may be priced higher.


ACT Street Disc

ACT Clutch - Street Disc

SIMPLY SMOOTH! ACT Street Discs are designed for smooth engagement, quiet operation and improved durability using only the best organic, spring center designs. When an ACT Modified Street Disc is available, the suffix "M" appears in the disc part number. The marcel of the disc has been modified to enable quicker action. When a special ACT Performance Organic Street Disc is available, the suffix "S" will appear. These discs use special steel backed performance linings designed to withstand high heat and abuse. Most of these "S" discs are also modified for quicker shifting. What is all the hype about different lining materials available ACT still contends that nothing can beat a good quality organic disc for street use. Virtually all the premium sport car manufacturers use organic discs. The Eclipse/Talon AWD Turbo is a good illustration. This application can be especially hard on clutches for several reasons: 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 (PN MBSD010S) when used with the ACT Xtreme Pressure Plate, many of the fastest Eclipse/Talon owners enjoy smooth engagement and record setting timeslips.
