ACT HD/Race rigid 6-pad clutch kit for 1971 Pontiac Firebird. The GM8-HDR6 kit pairs ACT’s Heavy Duty pressure plate—featuring an exclusive diaphragm design and precision cover stampings—with a rigid 6-pad race disc. Diaphragms undergo a four-stage heat-treating process; the race disc uses ceramic friction material and a heat-treated chrome-moly hub for strength, delivering quicker shifts and greater heat capacity. Engagement is harsher and the setup is recommended for larger clutch sizes; kit includes a one-year warranty.
