OS Giken

A famed machine shop since the times when the 510 Bluebird twincam L-head engine was a popular tuning base. Unlike its main racing clutch competition, Ogura Clutch (ORC) which manufactures clutches for a wide array of cars and other applications, OS Giken was established solely for producing tuning parts.

Since the early days of the company, OS Giken has been making new a innovative parts time and again, making them a commonly talked about in the tuning community. First they grabbed the attention of the public with their DOHC 4 Valve TC16-MAII/TC24-B1 engine in 1975. Then again in 2000 with the RB30 OS-E2996 Engine. Innovation from OS Giken came again two years later with the release of the RB26 Sequential Transmission, and the Super Lock LSD came the following year.

OS Giken continues to excel at bringing the tuning industry new and innovative products and will definitely continue to deliver high quality products for years to come.
