Clutch 7.25in 3-Disc Button Clutch

The ACE Racing Clutches Clutch 7.25in 3-Disc Button Clutch (R725011K3) is a high-performance triple-disc assembly engineered for GM V8 applications requiring aggressive power delivery and reliability under demanding conditions. This maxi-lite clutch kit combines a compact 7.25-inch diameter with three friction discs and ceramic material composition, delivering the holding capacity and modulation necessary for both street and track applications where factory clutch capacity has become a limiting factor.

The 1-1/16 inch by 10-spline interface is the OEM standard for many small-block and big-block GM V8 platforms, ensuring direct bolt-in compatibility without requiring flywheel modification. The rigid hub design eliminates damper springs, transferring power more directly to the transmission input shaft—a critical advantage when engine output exceeds stock specifications. Ceramic friction material provides superior heat dissipation and sustained clamping force across repeated high-torque engagements, a characteristic that separates purpose-built racing clutches from street-duty units. At 3.47 pounds, the maxi-lite construction minimizes rotational mass while maintaining the structural integrity required for consistent engagement across varied driving loads.

This clutch kit is purpose-built for engines exceeding factory horsepower and torque specifications—modified V8s, supercharged platforms, and vehicles engineered for consistent high-output performance. Builders and tuners select three-disc assemblies when single-disc options no longer provide adequate holding capacity without excessive pedal effort. The 7.25-inch diameter strikes a balance between capacity and drivability, maintaining manageable engagement characteristics for vehicles driven on varied road surfaces. Whether the application is drag racing, road course duty, or turbocharged street performance, the ACE Racing Clutches 3-disc design addresses the real-world requirement of multiplied friction surface area without sacrificing pedal modulation or clutch life.
