ACT Mod Twin 225 Heavy Duty Rigid Race Twin Disc Clutch Kit 2006-2025 WRX / 2005-2012 Legacy GT / 2006-2008 Forester XT

The Mod-Twin 225 HD Rigid Race Kit is engineered for high-powered AWD applications requiring aggressive launches and rapid shifting. This modular twin-disc design combines twice the ceramic friction surfaces with a solid Mono-Drive hub for maximum durability. The diaphragm spring undergoes a four-stage heat treatment for consistent, light pedal feel. Puck-style ceramic friction plates provide superior heat capacity, high friction coefficient, and long life. Torque is uniformly transferred through the chrome-moly Mono-Drive hub, heat treated for strength and extended input shaft life. The lightweight, rigid design ensures quick, precise shifts and trouble-free service. Includes CNC-machined, dynamically balanced flywheel, pressure plate, diaphragm spring, friction plates, rigid Mono-Drive hub, floater, Monoloc collar, release bearing, alignment tool, and pilot bearing (if required). Most components are rebuildable and available separately.
