ACT Pressure Plate Key Features- ACT pressure plates are available in a variety of designs, including all factory push, pull, crimp and rivet designs.
- ACT pressure plates feature a special, single-diaphragm design to dramatically increase clamp load without the adverse effects of double-diaphragm type clutches.
- Effective diaphragm designs are used to increase clam load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four-stage, heat treating process for unparalleled performance.
- All castings are CNC-machined for greater consistency and precision.
- 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.
- All ACT pressure plates are dynamically computer balanced for smooth operation at high RPM.
- A load test for every pressure plate is performed 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.
- Most ACT pressure plates are certified as meeting SFI Specification 1.1 and are legal for competition in all racing organizations where DFI certifications is required.
This pressure plate features an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All ACT diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency.
