OS Giken is a Japanese performance-parts manufacturer specializing in high-performance drivetrain and engine components. Officially founded in 1973, the company is headquartered in Okayama, Japan, where its products are manufactured and assembled under strict quality-control standards. OS Giken is best known for its multi-plate clutch systems, Super Lock limited-slip differentials, close-ratio gearsets and competition transmissions. Its engineering philosophy focuses on improving power transfer, durability and drivability through original mechanical designs rather than simply modifying factory-style components.

For Nissan Skyline GT-R and Nissan GT-R applications, OS Giken offers drivetrain upgrades for the R32, R33, R34 and R35 platforms. Available products include twin-, triple- and quad-plate clutch kits, front and rear Super Lock LSDs, clutch service components and the OS-88 six-speed sequential transmission for RB26-powered Skyline GT-Rs. The OS-88 is designed around the RB26DETT and is rated by OS Giken for applications producing up to 1,500 horsepower. For the R35 GT-R, OS Giken offers a Super Lock rear differential designed to provide smooth, progressive engagement and strong lock under power. Whether preparing a street-driven Skyline or a dedicated competition build, OS Giken provides precision drivetrain components developed for demanding power levels and performance use.
