ACT HD/Race sprung 4-pad clutch kit is a heavy-duty replacement built around ACT's high-clamp pressure plate and a spring-centered 4-pad race disc. The pressure plate uses a multi-stage heat-treated diaphragm for increased clamp load and consistency; the sprung race disc helps damp torsional vibrations while supporting quicker, firmer shifts. The kit is backed by ACT's one-year warranty and suits race or heavy-duty street use.
