ACT BM13-XTR4 Extreme Race Rigid 4-Pad Clutch Kit with Xtreme Pressure Plate

The ACT BM13-XTR4 Extreme Race Rigid 4-Pad Clutch Kit is engineered for maximum performance under the most demanding race conditions. This kit pairs an ACT Xtreme pressure plate with a 4-pad rigid ceramic race disc, delivering aggressive engagement and lightning-fast shifts for serious competition use. This kit also includes an ACT Prolite flywheel as a conversion kit.

Xtreme Pressure Plate:

• Exclusive diaphragm design increases clamp load, reduces deflection, and extends clutch life
• All diaphragms undergo a rigorous four-stage heat-treating process for maximum durability
• Precision cover stampings ensure rigidity and consistent clamping force
• 100% clamp load tested for quality assurance
• Dynamically computer spin-balanced to within 0.25 oz-in for smooth, reliable high-RPM operation

4-Pad Rigid Race Disc:

• High-quality ceramic friction materials provide excellent heat tolerance and peak performance
• Chrome-moly hub is heat-treated for superior strength and long-term durability
• Lightweight, rigid construction enables faster, cleaner shifts
• Well-suited for smaller disc sizes used in smaller displacement engines

Performance Characteristics:

• Moderate to heavy pedal effort with aggressive engagement feel
• Increased gear rattle is expected due to rigid disc design
• Rigid design may accelerate spline wear — factor into maintenance planning
• Moderate friction life, extended through ACT's exclusive diaphragm engineering
• Select ceramic friction materials chosen for high heat tolerance and maximum output

Recommended for race use only. The ACT BM13-XTR4 is not intended for street driving. This kit is ideal for competitive drivers who prioritize shift speed and power transfer over daily driveability.
