The ACT SB019X Xtreme Pressure Plate is engineered for performance-driven applications, providing an optimal balance of increased clamp load and durability. Utilizing an exclusive diaphragm design, this pressure plate enhances clamp load by 50 to 120 percent while minimizing deflection, resulting in improved clutch life and reliability under stress.
Each diaphragm undergoes a rigorous 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 reliable choice for both street and race environments. The Monoloc system serves as a direct replacement for the standard two-piece wedge collar and wire ring found in pull-type clutches, enhancing the overall design.
