Close Ratio Gear Set RB26DETT - 5th Gear

Close Ratio Gear Set: 

Performance driving and high-horsepower engines put a strain on the drivetrain and can sometimes lead to component failure, such as broken gears or input shafts. The purpose of the OS Giken Close Ratio Gear Set is to strengthen the internal components of the transmission while maximizing an engine's potential by providing customized gear ratios for performance driving.

Each OS Giken gear component is designed and constructed from high-quality forged materials, then undergoes hard shot blasting, resulting in increased strength and durability. In addition, the gears are helical-cut, rather than straight-cut, to ensure quiet and smooth operation, ensuring complete comfort for street use and reliability for racing purposes.
