Clutch 5.5in 3-Disc Pack

The Clutch 5.5in 3-Disc Pack from ACE Racing Clutches delivers the reliable friction engagement that high-performance racing and heavy-duty automotive applications demand. This three-disc set replaces worn or glazed clutch plates in vehicles where precision clutch modulation is critical to power delivery and driveline longevity. Whether upgrading a street rod, competition vehicle, or industrial equipment, these discs restore smooth engagement and prevent slippage under load.

Each disc features a 5.5-inch diameter with a rigid hub design and 10-spline internal drive geometry, engineered for positive torque transfer without chatter or flutter. The 1/16-inch thickness specification ensures proper clearance in standard clutch stacks while maintaining robust friction material bonding. ACE Racing's manufacturing process produces discs with consistent friction coefficients across the contact surface, delivering predictable engagement curves and reducing the shock loads that can damage flywheel and pressure plate surfaces. The universal fitment across this pack makes it suitable for multiple vehicle platforms using comparable clutch architectures.

Technicians and enthusiasts benefit most from this three-disc configuration, as it addresses typical wear patterns in both automatic and manual transmission clutch packs. The rigid hub minimizes radial play, ensuring centered disc rotation and even wear distribution throughout the assembly. Installation requires proper clutch drum or basket inspection and correct torque sequencing to maximize disc lifespan. Compatible with vehicles using 10-spline hub platforms, this pack delivers OEM-quality performance at a competitive price point for replacement or rebuild applications.
