The ACT HD/Race sprung 6‑pad clutch kit for 1971 Pontiac Firebird combines a Heavy Duty pressure plate with a spring‑centered race disc to handle torsional vibration and harsh duty. The spring center and reinforced retainers damp vibrations and increase strength, producing quicker shifts and harsher engagement suited to larger clutch sizes and high‑heat conditions.
