OS Giken, since 1973
Renowned Japanese racing parts specialists OS Giken Co Ltd have been part of the tuning and racing scene since 1973. In the mid seventies the company first gained notoriety for their twin-cam head design for Nissan L-series four and six-cylinder engines. From 1982 production of multi-plate racing clutches began and these have been the key OS Giken product ever since.
Later OS Giken developed more special racing parts, like the patented Superlock LSD, the RB30 racing engine and OS-88 sequential transmission for GT-R and most recently the patented Grand Touring series clutches. In all cases, OS Giken strives for the pinnacle of durability and performance.
