Product Description

The Clutch Masters 850 PRO Series Rigid Race kit steps up from the 725 PRO platform with a larger 8.5" twin-disc assembly, built for the turbocharged 2.3L Mazdaspeed3 and Mazdaspeed6 running well beyond stock power. Two ceramic discs ride on a driven rigid hub, and the 12-point nut-and-stud steel mounting system replaces the older 6-post aluminum design for a meaningful jump in structural integrity under sustained high-heat, high-abuse use.

Like the rest of the PRO lineup, this is a conversion kit built exclusively around the included Clutch Masters steel flywheel rather than a factory-style replacement. It's aimed at street, drag, or track builds where the 725 PRO twin-disc kit has run out of headroom and more torque capacity is needed.
