ACT BM2-HDSS Heavy Duty/Performance Street Sprung Kit

The ACT BM2-HDSS Heavy Duty/Performance Street Sprung Kit is engineered for those who demand reliability and performance from their clutch system. This kit features ACT's renowned Heavy Duty pressure plate, designed with an exclusive diaphragm that enhances clamp load while minimizing deflection. The result is a clutch that not only lasts longer but also performs consistently under various driving conditions.

Construction and Design

Each pressure plate undergoes a meticulous four-stage heat-treating process, ensuring superior performance and longevity. The precision cover stampings contribute to the rigidity and consistency of the pressure plate, making it a solid choice for both street and light racing applications.

Performance Street Disc

The Performance Street disc included in this kit is crafted from premium organic materials, featuring a high copper content that improves heat transfer. The steel-backed lining enhances burst strength and durability, while the reduced marcel design allows for quicker shift action, perfectly complementing the Heavy Duty pressure plate.
