ACT |
As every driver, engine, and application is
different, ACT offers a variety of complete clutch kits. You may also
purchase individual clutch components. The ACT application chart will
have a line for each kit available. To the right of the clutch kit
number, you will fine individual part numbers the clutch kit consists
of. 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 application chart is designed to help you decide
which level of performance and characteristics are best for your
vehicle. To choose which clutch kit is right for your vehicle, read our
Product Information on the following pages. Also review the torque
capacity and increase in clamping force for each clutch kit when making
your decision. |

Heavy Duty Pressure Plates
|
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. |

Xtreme Pressure Plates |
NO MERCY! ACT Xtreme Pressure Plates deliver
the maximum holding power available! For high horsepower streetcars,
combine this high clamp pressure plate with and 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 ultimate in 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 can be 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
indicated 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. It's Xtreme to the
MaXX! |

Copper Ceramic Race Discs (Xtreme Discs) |
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 forsmoother 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. The ACT application chart lists only those ACT Xtreme Race
Disc used with ACT Heavy Duty and Xtreme Pressure Plates. |

Street Discs |
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
serveral 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. |
