The ACT AR1-HDSS kit is engineered for those who demand reliability and performance in their clutch system. This kit combines ACT's Heavy Duty pressure plate with a high-performance street disc, making it suitable for both spirited driving and daily use.
ACT's Heavy Duty pressure plates utilize a unique diaphragm design that enhances clamp load while minimizing deflection. This design contributes to increased clutch longevity. Each diaphragm undergoes a rigorous four-stage heat treatment process, ensuring superior performance under stress. The precision cover stampings provide added rigidity and consistency, vital for maintaining performance across various driving conditions.
The included Performance Street disc features premium organic materials with a high copper content, enhancing heat transfer capabilities. Its steel-backed lining improves burst strength and durability, making it resilient against wear. The disc is designed with reduced marcel for quicker shift action, which works in harmony with the Heavy Duty pressure plate for seamless gear changes.
