ACT 4224508-1 Sprung Race Clutch Disc - 4-Pad

The ACT 4224508-1 is a high-performance 4-pad spring-centered race clutch disc engineered for serious motorsports applications. Featuring premium ceramic friction materials, this race disc delivers aggressive engagement and lightning-fast shifts while maintaining moderate wear rates and exceptional heat tolerance.

Key Features:

• Premium ceramic friction materials with 28% more torque capacity than typical organic clutch materials
• 4-pad design optimized for race applications with aggressive engagement characteristics
• Heavy-duty torsional dampening springs stronger than standard springs, sized and rated specifically for demanding performance use
• Heat-treated spring steel drive plate provides superior burst strength and reliability under extreme conditions
• Wraparound spring windows and thicker retainer stampings reduce stress concentrations and increase overall strength
• Spring-centered design allows for faster shifting with OE to mild gear rattle

This race disc is particularly well-suited for smaller disc sizes in compact, high-revving engines where quick engagement and maximum torque transfer are critical. The ceramic construction offers excellent thermal stability for track use and repeated high-temperature cycles. Recommended for race use only due to aggressive engagement characteristics that may be too harsh for street driving.
