Through rigorous research and development of high performance engines, we realized the need for the production of higher quality, more durable clutch systems to meet the rigorous demands of race and sport driving. OS Giken multi-plate clutch is able to transmit engine revolutions and output to the drivetrain without loss. They are made of the highest quality materials and their durability is second to none. OS Clutches are designed to meet the demands of even the most heavily modified vehicles.
In spite of its decreased diameter, OS Giken clutch allows for extremely efficient power transfer and improved engine response. OS Giken 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 vehicles potential.
The STR series of twin plate clutches were designed for daily driven high performance vehicles. STR clutches provide the comfort of the stock clutchs pedal feel and the strength of a race ready twin plate. Whether it be a lap around the track or a trip to the corner store, the STR twin plate clutch equally handles each task with ease.
