Distinctive Features of the OS Multi-Plate Clutch:

In spite of its decreased diameter, our clutch allows for extremely efficient power transfer and improved engine response. Our redesigned leverage mechanism of the diaphragm spring on the center cover results in higher pressure of the clutch disk while reducing pedal effort. In addition, ventilation holes are designed to reduce heat generated inside the clutch system and allows for the friction plate dust to exit outside the clutch system, thus increasing reliability and safety. All OS Giken clutches include a corresponding performance flywheel to ensure maximum performance and unlock your vehicle’s potential.

RACING MULTIPLATE

TS2AD, TS2B, TS2CD and TS3CW are our new OS Racing Clutch series and their friction plates are made of heat treated metal. These materials are carefully selected and alloyed so that the plates match with the materials of the flywheel and center plate to improve durability and maximize performance.

The TS2A and the TS2B are our longest selling models and have established a bulletproof reputation for performance and durability on the racetrack time and again.

The R series are revised versions s of the TS2AS and TS2BD. They are specifically designed for large single turbo charged engines found in many of today's racing cars.
