Description
The ACT Mod-Twin 225 HD Sprung Race Clutch Kit is engineered for high-horsepower AWD racing applications that demand exceptional torque capacity, aggressive launch capability, and superior heat resistance. Designed specifically for the Nissan Skyline GT-R R34, this twin-disc race clutch combines dual ceramic friction surfaces with a sprung Mono-Drive hub assembly to deliver outstanding power transfer while helping reduce driveline shock.
Rated for an impressive 895 ft-lbs of torque and offering approximately 123% greater torque capacity than the factory clutch, the Mod-Twin 225 HD Sprung Race Kit is built to handle the extreme demands of drag racing, road racing, and rally competition. Its ceramic friction material provides a high coefficient of friction, superior heat tolerance, and excellent durability under repeated high-load conditions.
The sprung Mono-Drive hub assembly helps extend transmission input shaft life while reducing torsional vibration and drivetrain shock. Combined with ACT's fully rebuildable modular twin-disc architecture, this clutch kit delivers long-lasting performance and serviceability for serious motorsport enthusiasts.
