  • Key Features
  • Diaphragms are induction hardened on the release bearing contact area to reduce wear and promote smooth operation.
  • Cover stampings are sometimes reinforced by ACT to reduce flex and improve the efficiency and feel of the pressure plate.
  • Stronger drive straps and rivets are used when needed to strengthen the pressure plate and prevent breakage.
  • Up to four clamp load ratings are available (some applications) - choose between a Sport, Heavy Duty, Xtreme or MaXX Xtreme pressure plate.
  • We load test every pressure plate on a special computerized testing press for quality assurance. This same machine also assists in designing new products and evaluating parts that are in for service.
  • Proper release travel, clamp load, pedal effort, and working range are analyzed using specialized testing equipment and software.
  • All castings are CNC machined for greater consistency and precision
  • ACT pressure plates feature a special single diaphragm design to dramatically increase clamp load without the adverse affects of double diaphragm type clutches.
  • Precision cover stampings provide rigidity, consistency and are cost effective.
  • Creative diaphragm designs are used to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four stage heat treating process for unparalleled performance.
  • Most ACT pressure plates are certified as meeting SFI Specification 1.1. and are legal for competition in all racing organizations where SFI certification is required.
  • All ACT pressure plates are dynamically computer balanced for smooth operation at high rpm.

    Street Discs
  • Quiet operation from OE quality torsional dampeners
  • Increased clutch life
  • Reduced fade - increased heat tolerance which helps prevent warping of mating surfaces





    Stock Street Disc - 00
  • Recommended for Street
  • Smooth engagement
  • Very quiet operation
  • Good burst and hub strength
  • Modified Street Disc - MM
  • Recommended for Street or occasional Race
  • Quicker engagement
  • Quiet operation
  • Improved friction material and/or hub strength
  • Performance Street Disc - SS
  • Recommended for Street and Race
  • Quicker engagement
  • Quiet operation
  • Best organic friction material, improved hub and burst strength


  • Key Features
  • ACT carefully selects the right amount of cushioning between the linings to allow for good engagement characteristics without sacrificing performance.
  • Most ACT spring centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening which improves clutch life and reduces noise.
  • Spring retainers by ACT utilize a wrap around spring window that not only gives liberal support for the springs, but also reduces stress concentrations that are a common cause for failure. (Offered on most ACT Modified and Performance Street Discs)
  • ACT performance linings are steel backed for maximum burst and rotational strength.
  • We carefully broach our splines to ensure exact fit onto transmission input shaft for long spline life and better clutch release.
  • Heavy duty torsional dampening springs are stronger in most cases than standard springs and are provided in the best sizes and spring rates to suit the application.
  • ACT Performance Street Discs feature a high copper content friction material. Through the use of copper the heat is pulled away from the surface. ACT achieves better heat tolerance and faster recovery from overheating.
  • Top grade rivets are used to securely fasten the part together. Rivet design and rivet materials are carefully selected for maximum strength.
  • Spring windows on most ACT street discs are heat treated to resist wear, increase strength and reduce the chance of springs "popping" out.
  • ACT provides thicker retainer stampings for increased strength and reliability. (Offered on most ACT Modified and Performance Street Discs)
  • All modified, performance and many standard replacement discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification.
  • Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency.

    Race Discs
  • Quicker shifting due to reduced weight
  • Higher torque and heat capacity than organic discs with fade free characteristics
  • Longer clutch life through ACT's careful selection of materials and features
  • SFI to insure safety



    Solid Hub (4 Pad) Race Disc - R4
  • Recommended for Drag and Road Racing
  • Increased torque capacity
  • Fastest shifts, low inertia
  • Good durability but shortened spline life
  • Harsh engagement, chatter
  • Solid Hub (6 Pad) Race Disc - R6
  • Increased torque capacity
  • Faster shifts, reduced inertia
  • Very good durability but shortened spline life
  • Absorbs more heat than 4 pad
  • Harsh engagement, some chatter
  • Spring Centered (4 Pad) Race Disc - G4
  • Recommended for Road Racing
  • Increased torque capacity and spline life
  • Good durability and spline life
  • Quiet operation, reduced driveline shock
  • Very harsh engagement, chatter
  • Spring Centered (6 Pad) Race Disc - G6
  • Recommended for Road Racing and high power Street
  • Increased torque capacity and spline life
  • Very good durability and good spline life
  • Quiet operation, reduced driveline shock
  • Harsh engagement, chatter


  • Key Features
  • All drive plates are high carbon spring steel that is heat treated and black zinc plated to resist bending, cracking, fatigue and rust even under severe racing conditions.
  • ACT uses thicker retainer stampings for increased strength and durability.
  • Spring windows are heat treated to resist wear, increase strength and reduce the chance of springs "popping" out from hub wear.
  • Hub forgings are CNC machined for precision and consistency.
  • All friction pads are measured, sorted and matched before assembly to insure that each disc is uniform in thickness.
  • All ACT spring center race disc hub assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening which improves clutch life and reduces noise.
  • ACT carefully selects rivet design and materials for maximum strength. Solid center discs use 16 hub rivets for high torque and shock tolerance.
  • Heavy duty torsional dampening springs are stronger than standard springs and are offered in three sizes and spring rates. No more warped inserts or loose ring gears.
  • Premium ceramic friction materials provide high heat tolerance, high coefficient of friction and low wear rates. Our pads will hold approximately 28% more torque than standard organic materials.
  • Spring retainers utilize a wrap around spring window that not only gives liberal support for the springs, but also reduces stress concentrations that are a common cause for failure.
  • We carefully broach our splines to ensure exact fit onto transmission input shafts for long spline life and better clutch release.
  • SFI certification is provided on all ACT race discs. ACT race discs are legal for competition in all racing organizations that require SFI certification.
  • Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency.
