ACT NX1-HDSS Heavy Duty/Performance Street Sprung Kit

The ACT NX1-HDSS kit is engineered for those seeking a robust clutch solution that balances street performance with durability. It features ACT's renowned Heavy Duty pressure plate and a Performance Street disc, designed specifically for high-demand environments.

Pressure Plate Design

The Heavy Duty pressure plate utilizes an exclusive diaphragm design that enhances clamp load while minimizing deflection, ultimately extending the lifespan of the clutch. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring superior performance under stress. Precision cover stampings add rigidity and consistency, crucial for maintaining performance during aggressive driving.

Performance Street Disc

The Performance Street disc is constructed with premium organic materials that boast a high copper content, optimizing heat transfer and reducing fade during operation. The steel-backed lining increases burst strength and overall durability. With a reduced marcel, this disc allows for quicker shift action, making it an excellent match for the Heavy Duty pressure plate.
