ACT SB12-HDR6 Heavy Duty Race Rigid Clutch Kit - 6-Pad

The ACT SB12-HDR6 Heavy Duty Race Rigid 6-Pad Clutch Kit is engineered for high-performance and racing applications where maximum torque capacity and rapid shifts are essential. This complete clutch kit combines ACT's proven Heavy Duty pressure plate with an aggressive 6-pad rigid race disc to deliver uncompromising performance under demanding conditions.

Heavy Duty Pressure Plate Features:

• Exclusive diaphragm design increases clamp load, reduces deflection, and maximizes clutch life
• Four-stage heat-treating process for unparalleled durability and performance
• Precision cover stampings provide rigidity and consistency
• Computer spin-balanced to within 0.25 oz-in for smooth high-RPM operation

6-Pad Rigid Race Disc Construction:

• High-quality ceramic friction materials for superior heat tolerance
• Heat-treated chrome-moly hub for exceptional strength and durability
• Lightweight rigid design enables quicker shifts and trouble-free service
• Recommended for larger clutch sizes to effectively absorb and dissipate heat

Performance Characteristics:

The 6-pad rigid race disc delivers harsher engagement but significantly faster shifting compared to stock clutches. Expect increased pedal effort of 15-40% over stock, which is a trade-off for the enhanced torque capacity and longevity. This kit is recommended for race use and serious performance applications.

Important Notes:

ACT race discs typically require only a few hard slips to properly lap in the friction surfaces before normal use. The rigid design may increase spline wear compared to sprung discs, but provides the quickest shifts and most direct power transfer available.
