ACT MB1-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit

MB1-HDG6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. HD/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT MB1-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit is engineered for high-performance street and race applications that demand reliable power transfer, fast shifting, and increased heat resistance. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad, spring-centered race disc designed to withstand demanding driving conditions while maintaining controlled torsional vibration damping.

The Heavy Duty pressure plate uses ACT’s exclusive diaphragm design to increase clamp load, reduce deflection, and help maximize clutch service life. The diaphragm is heat-treated through a four-stage process, while precision cover stampings promote rigidity and consistent operation. The spring-centered 6-pad disc uses reinforced spring retainers with wraparound spring windows and thicker stampings to support the springs, reduce stress concentrations, and improve durability. Engagement is more aggressive than an organic street clutch, but shifting is faster and more direct.

The ACT MB1-HDG6 is carefully engineered, precisely assembled, accurately balanced, and 100% clamp-load tested. Select ceramic friction materials provide high heat tolerance and dependable performance during repeated high-load use. It offers light to moderate pedal effort, aggressive engagement, moderate friction life, and OE to mild gear rattle characteristics. The kit is recommended for high-horsepower street or race use and includes ACT’s one-year limited warranty. Fitment data indicates compatibility with select 1995–1998 Mitsubishi Eclipse and 1998 Mitsubishi Galant applications; verify vehicle-specific drivetrain details before installation.
