The ACT HD/Race sprung 4-pad clutch kit for 1970 Toyota Corona is a heavy-duty replacement kit chosen for durability and controlled engagement in demanding use. It upgrades the stock clutch with components aimed at higher clamp loads and improved longevity. The kit pairs ACT’s Heavy Duty diaphragm pressure plate—four-stage heat-treated for consistent strength—with a spring-centered 4-pad race disc that damps torsional vibration for quieter operation and greater reliability under load.
