The MB2-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular street disc, sized for the twin-turbo 3.0L platform shared by the Dodge Stealth R/T Turbo and Mitsubishi 3000GT VR-4. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life; every diaphragm goes through a four-stage heat-treating process, and cover stampings are precision-made for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for better heat transfer, plus a steel-backed lining for greater burst strength and durability. Reduced marcel gives faster shift action while keeping engagement smooth for daily driving.
