Product Description

The ACT MB012X is a high-performance Xtreme diaphragm pressure plate engineered for serious driving applications. Designed to deliver 50-120% more clamp force than standard pressure plates, this unit features a robust diaphragm that's heat-treated in four stages to maximize durability and minimize deflection.

Precision cover stamping ensures structural rigidity, while the full assembly is dynamically balanced and 100% clamp-load tested to handle high RPMs with confidence. Pedal feel is moderate to heavy, offering aggressive engagement ideal for both street and race environments. Pair this with a compatible street or race disc to unlock its full potential.
