Description
The ACT Mod-Twin 225 HD Rigid Race Clutch Kit is designed for high-powered AWD race vehicles that require exceptional torque holding capability, rapid gear changes, and uncompromising durability. Engineered specifically for the Nissan Skyline GT-R R34, this competition-focused twin-disc clutch system combines dual ceramic friction surfaces with a rigid chrome-moly Mono-Drive hub to deliver maximum power transfer and outstanding performance in demanding motorsports environments.
Capable of handling up to 895 ft-lbs of torque, the Mod-Twin 225 HD Rigid Race Kit provides approximately 123% greater torque capacity than the factory clutch system. The ceramic puck-style friction discs deliver a high coefficient of friction and exceptional thermal capacity, making this clutch ideal for repeated aggressive launches and sustained high-load racing conditions.
The rigid Mono-Drive hub features a heat-treated chrome-moly construction with a continuous spline design for maximum strength, durability, and improved transmission input shaft life. Its lightweight rigid architecture provides direct engagement and faster shifts, making it an excellent choice for drag racing, road racing, and rally competition.
