Action Clutch staged kits come complete with the clutch disc, pressure plate, throwout/release bearing, pilot bearing/bushing (when applicable), and alignment tool. Action Clutch Stage 3 clutch kits for heavy-duty street and occasional drag/road/drift racing offer a 170 percent increased holding capacity. They utilize extremely durable, high performance MIBA sprung ceramic discs and feature a single diaphragm heavy-duty pressure plate with reinforced drive straps for increased durability. They are available in a 4- and 6-puck configuration with the 4-puck being the more aggressive of the two.
