ACT AI4-XXR4 MaXX/Race Rigid 4 Pad Kit

The ACT AI4-XXR4 MaXX/Race Rigid 4 Pad Kit is engineered for performance-driven applications, utilizing advanced technology to enhance your vehicle's clutch system. This kit features the MaXX pressure plate, which incorporates an exclusive diaphragm design that increases clamp load while minimizing deflection. This design ensures optimal clutch life and performance under demanding conditions.

Construction and Design

Each diaphragm undergoes a rigorous four-stage heat-treating process, delivering exceptional durability and performance. The precision cover stampings of the ACT pressure plates provide added rigidity and consistency, essential for high-performance applications. The 4-pad rigid race discs are constructed from premium ceramic friction materials, designed to withstand high temperatures and deliver reliable performance.

Performance Characteristics
