Product Description

ACT's Xtreme pressure plate utilizes a unique diaphragm design, boosting clamp load, minimizing deflection, and extending clutch longevity. Through a rigorous four-stage heat-treating process, all diaphragms ensure top-notch performance. Precision cover stampings in ACT pressure plates offer both rigidity and uniformity. With a 50 to 120 percent increase in clamp load, these plates are ideal for pairing with either street or race discs, ensuring optimal performance and durability.

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.
