ACT NS1-HDSS Heavy Duty Performance Clutch Kit

The ACT NS1-HDSS kit is engineered for those who demand reliability and performance from their clutch system. This kit combines ACT's Heavy Duty pressure plate with a Performance Street disc, designed specifically for enhanced engagement and durability in demanding driving conditions.

Pressure Plate Design

The Heavy Duty pressure plate utilizes an exclusive diaphragm design that increases clamp load while minimizing deflection. This results in improved clutch life and performance. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring exceptional endurance under high-stress conditions. Precision cover stampings guarantee rigidity and consistent performance, making it a dependable choice for both street and track applications.

Performance Street Disc

ACT's Performance Street disc is crafted from premium organic materials with a high copper content, enhancing heat transfer and durability. The steel-backed lining provides greater burst strength, while reduced marcel allows for quicker shift action. This design complements the Heavy Duty pressure plate, offering increased reliability during aggressive driving.
