Product Description

ACT’s pressure plate boasts an innovative diaphragm design, enhancing clamp load and extending clutch lifespan. Through a rigorous four-stage heat-treating process, ACT ensures unmatched performance in all diaphragms. Precision cover stampings contribute to rigidity and consistency in our pressure plates. Notably, our Heavy Duty variants elevate clamp load by 20-50%, ideal for both street and race discs.

ACT Clutch Pressure Plate Features:

• All Factory Designs: ACT offers pressure plate assemblies for all types of factory designs, including those with push-type, pull-type, crimp, and rivet setups.
• Stiffening Ribs: Some models come with stiffening ribs on the diaphragm fingers to make the pedal feel more responsive and reduce how far you have to push it.
• SFI 1.1 Specification: Pressure plates that meet the SFI Specification 1.1 are approved for racing in organizations that require this certification.
• Proprietary Single Diaphragm: ACT’s special single-diaphragm designs make the pressure plate stronger without making it more complicated.
• Reinforced Cover Stamping: The cover stampings are made stronger to prevent bending, which makes the clutch work better and the pedal easier to press.
• Computer Spin Balanced: Each pressure plate is balanced by a computer to make sure it spins smoothly at any speed.
• Stronger Drive Straps & High Grade Rivets: Some models have stronger straps and rivets to handle higher power and speed.
• CNC Machined Face Castings: The faces of the pressure plates are carefully shaped by a computer for the best fit and performance.
• 4 Stage Heat Treated: The springs in the pressure plate are heated and cooled in four stages to make them stronger and last longer.
• Load Tested: Each pressure plate is tested to make sure it can handle the force it will experience in real-world use.
