Construction & Design

The OS Giken TR2CD clutch features a billet aluminum cover that offers superior strength and heat dissipation compared to traditional stamped steel covers. This construction helps maintain clutch integrity during high-heat scenarios typical of racing and spirited driving. The diaphragm spring's innovative leverage mechanism reduces pedal effort, making daily driving more comfortable without sacrificing holding power. The friction materials are carefully selected for their high heat resistance and consistent engagement, ensuring reliable performance even after repeated aggressive launches or prolonged track sessions.
