The renowned brand Advanced Clutch Technology (ACT) has earned a great reputation in past few decades. The brand is known for its high-performance products and reliable driveline components in the market. From top-notch customer service to delivering quality products, the brand does not compromise on its coveted reputation. ACT products have been improved considerably in the past few years due to the integration of the latest technology for better street performance. Advanced CAM tools, FEA, and CAD stimulation ensure an unparallel and optimized performance. Not only this, it is hard to find a match for this brand, when it comes to durability and reliability. There is no denying that ACT is quintessential in terms of best design methodologies, product engineering and use of high-end materials. The brand has the best manufacturing techniques such as chromoly steel forging to align grain structures. ACT clutch is an example of ACT's unique products. It comes with steady pedal feel, durability, consistent torque capacity, and high functionality.

AR1-XTR4 kit features an Xtreme pressure plate for the most demanding driver. ACT Xtreme pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

  • Moderate to heavy pedal effort, aggressive engagement, increased gear rattle.
  • Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear.
  • Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended for race use only.
  • 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.
