ACT MaXX/Race Rigid 4 Pad Kit MS1-XXR4

The ACT MaXX/Race Rigid 4 Pad Kit MS1-XXR4 is engineered for performance-driven applications, focusing on durability and efficiency. This kit features a MaXX pressure plate designed specifically for serious automotive applications, utilizing a unique diaphragm design that enhances clamp load while minimizing deflection. This results in increased clutch life, making it a reliable choice for high-performance setups.

Construction and Design

Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring superior performance under demanding conditions. The precision cover stampings of the pressure plate contribute to its rigidity and consistent performance, essential for competitive driving.

Disc Features

The 4-pad rigid race disc is constructed from high-quality ceramic friction materials, providing excellent heat tolerance and performance. The chrome-moly hub is heat-treated, adding strength and durability to the design. This lightweight, rigid construction allows for quicker shifts, enhancing overall driving dynamics. However, note that the engagement is more aggressive, resulting in a harsher feel during operation, which is typical for race-oriented applications.
