Heavy Duty / Race 6-Pad Rigid Clutch Kit by ACT

ZM10-HDR6 kit features ACT's most popular Heavy Duty pressure plate and their 6-pad, rigid race disc.

CT 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 rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat.


  • Feel - Light to moderate pedal effort, aggressive engagement, increased gear rattle
  • Life - Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
  • Quality - Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended Use - Recommended for race use only
  • ACT Difference - 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Please Note: 225mm upgrade. Must use ACT flywheel (included in kit).
