OS Giken Products at //AWRperformance
Company Background OS Giken was formed in the early 1970's by a man named Osamu Okazaki, with strength, durability, and the pursuit of high performance in mind. These goals for product development remain true today while OS Giken has established itself in the upper-echelon for designing and manufacturing high quality, high performance, and supremely durable parts. From Okazaki's humble beginnings tinkering with motorcycle parts at home, OS Giken has evolved and grown over the years, building and cementing a reputation as one of the best racing drivetrain parts manufacturers in the world. Officially founded in 1973, the company headquarters and factory are located in Okayama, Japan. All OS Giken parts are 100% manufactured and assembled in Japan, under very strict quality-control guidelines. Production and design capabilities for engine and drivetrain components are OS Giken's specialty, but the company has the ability to design and build just about anything mechanical. As the design, construction, and usage of the automobile evolves, OS Giken looks forward to the challenges presented to find room for improvement. Product Lines
-Performance Clutch Kits Through OS Giken's research and development of high performance engines, they realized the need for the production of higher quality and more durable clutch systems to meet the rigorous demands of racing. By utilizing high-quality materials and superior manufacturing techniques, OS clutches are renowned for durability and the ability to effectively transmit engine power with minimal loss. Continual research and development has helped OS Giken create clutches that can meet the demands of even the most heavily modified vehicles.
-Close Gear Ratio Kits Performance driving and high output engines put strain on the drivetrain and can sometimes lead to failing components, such as broken gears or input shafts. The goal of the OS Giken Close Ratio Gear Kit is to reinforce the transmission internal components while maximizing an engine’s potential by providing custom gear ratios for performance driving. Each OS Giken gear component is designed and created from high-quality forged materials, and then undergoes hard shot peening, resulting in increased strength and durability. Furthermore, the gears are helical-cut, rather than straight-cut, to maintain a quiet and smooth operation, accomplishing full comfort for street driving as well as reliability for racing
