Action Clutch ACR-3677 Stage 3 Transmission Clutch Kit (1MS)

The Action Clutch ACR-3677 is a Stage 3 (1MS) Transmission Clutch Kit engineered for drivers who demand peak performance and exceptional durability. Built around a heavy-duty single diaphragm pressure plate with reinforced drive straps, this kit centers on a Sprung MIBA Ceramic disc (available in a 4 or 6 puck configuration) that delivers quicker engagement and a 170% increase in holding capacity over the factory clutch. Some clutch chatter is normal with ceramic disc setups and will minimize after a proper break-in period. Designed for heavy-duty street use and occasional drag, road, or drift racing, this kit is ideal for low to mild horsepower builds where reliability cannot be compromised.
