Street
/ Strip Discs
Organic,
spring center replacement disc designed for smooth engagement,
quiet operation and improved durability. We offer the best brands
for the application. Street ACT Clutch 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 act Performance
Organic 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. If you have questions about
a certain application consult us. With all the hype about different
lining materials available we 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 Performance Organic Street Disc, many
of the fastest Eclipse/Talons owners enjoy smooth engagement,
11 second and even 10 second timeslips. This same act 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 act 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 ACT Clutch
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. ACT Clutch 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. Our application chart
lists only those racing discs used with our pressure plates although
we fit many other cars not listed on our chart. If you have any
questions regarding ACT Clutch applications not listed, consult
us.

Heavy
Duty Pressure Plates
Great
holding power, better 60ft & 1/4 mile times, and long life are
all benefits that come along with these plates. What makes our
ACT Clutch pressure plates the highest standard of the industry?
First, we start off with new ACT 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 ACT Clutch diaphragms are specially heat
treated through an exclusive 3 stage process and then hardened
on the 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 unit we produce. No guesswork,
no hype, only proven engineering and calculated results.

Xtreme Pressure Plates
The maximum holding power available! Our solution: apply more
diaphragm pressure. With a less aggressive ACT Clutch street
disc, this makes a great combination for high HP street cars
that prefer smooth engagement. For racing, combine our act Xtreme
Pressure Plate with our ACT Clutch 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, like the one
shown above, we actually include gusseting the cover to reduce
flex caused by the the high pressure. These 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! ACT Clutch Xtreme Pressure
Plates can be identified throughout the application chart when
the pressure plate number is followed by a suffix "X".
