OS Giken - Clutches:

OS Giken Clutches:
Through our 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. Our OS multi-plate clutch is able to transmit engine revolutions and output to the drive train without loss. They are made of the highest quality materials and their durability is second to none. Our continual research and development has brought about many improvements since our multi-plate clutch line's original debut in 1983 and we are confident that our clutches can meet the demands of even the most heavily modified vehicles.




Supersingle Clutch:

Our Super Single series make an ideal choice as a replacement to the original equipment clutch/flywheel and provide your vehicle with unparallel response and race performance. The Supersingle clutch design is a product of our cumulative knowledge and experience in developing and refining our Racing Multiplate Clutch line.



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.






OS Giken Super Lock LSD:
OS Giken utilized its accumulated racing knowledge and engineering experience to develop its own limited slip differential. Four years of extensive research and development lead to a new and revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total) and thus the OS Super Lock LSD was born. The increased number of plates directly has not only dramatically improved our LSD design's locking force and enables it to lock fully and completely. An added benefit to being a fully locking mechanism is that less heat is generated, thus resulting in incredible durability and reliability.

As expected from OS Giken, our LSDs are not only made from the highest quality materials, our precise machining, forged gears, and sound engineering makes our LSDs the most durable and reliable race performance LSDs available.
In addition, our design allows for the initial torque setting and lock timing to be customized to best fit you vehicle's everchanging set-up and course/road conditions. (Limited to Spec-X LSDs only)
