ACT ZM15-HDR6 HD/Race Rigid Clutch Kit - 6-Pad

The ACT ZM15-HDR6 is a Heavy Duty Race Rigid 6-Pad Clutch Kit engineered for drivers who demand maximum performance from their drivetrain. This kit pairs ACT's industry-leading Heavy Duty pressure plate with an aggressive 6-pad rigid race disc, delivering the torque capacity and shift speed required for track and competition use.

Pressure Plate Features:

• Exclusive diaphragm design increases clamp load, reduces deflection, and maximizes clutch life
• All diaphragms undergo a four-stage heat-treating process for consistent, high-performance clamping force
• Precision cover stampings provide rigidity and consistency under sustained load
• 100% clamp load tested and dynamically computer-balanced to within 0.25 oz-in for smooth high-RPM reliability

6-Pad Rigid Race Disc Features:

• High-quality ceramic friction materials for superior heat tolerance and maximum grip
• Chrome-moly hub is heat-treated for strength and long-term durability
• Lightweight rigid design enables quicker, more precise shifts
• Recommended for larger clutch sizes where greater heat absorption is required

Performance Notes:

• Expect a 15–40% increase in pedal effort compared to stock (Heavy Duty rating)
• Engagement is more aggressive than street-oriented clutches — shifting is faster but engagement feel is firmer
• Recommended for race use; not intended as a direct OEM street replacement

The ACT ZM15-HDR6 clutch kit is precision-engineered, carefully assembled, and computer-balanced for reliable performance across the full RPM range, making it the ideal upgrade for competitive and high-performance driving applications.
