Close Ratio Gear Set RB26DETT for 1st, 2nd and 3rd Gear with Reinforced Input Shaft (Hollinger Spline)

Close Ratio Gear Set: 

Performance-oriented driving and high-powered engines place 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 the engine's potential by providing customized gear ratios for performance driving.

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