||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?
* ACT manufacturing always begins
with new units. ACT Pressure Plates are not rebuilt from worn out parts.
* 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.
* ACT designs the pressure and release travel of the unit to be in the
optimum working range.
* ACT assures consistency and precision by using proven assembly procedures.
Every unit ACT produces is accurately balanced and tested. No quesswork,
no hype, only proven engineering and calculated results for every ACT
Heavy Duty and Xtreme Pressure Plate.
||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
an ACT Street Disc to maintain smooth engagement and obtain high torque
capacity. For racing, combine the ACT Xtreme Pressure Plate 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". Please contact the ACT technical
staff for availability and applications. Xtreme Clutches for the Xtreme
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 performance linings designed to withstand high heat and abuse. Most
of these "S" discs are also modified for quicker shifting.
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/Talons owners
enjoy smooth engagement and record setting timeslips.
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 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.
