Overview

ACT Race Clutch Discs

ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions.

Additional product details:
