Description

The Pfitzner Performance Gearbox SU-6S4GV2DB-GA is a 1st-4th drag racing gear set specifically developed for the Subaru WRX STI 6-speed gearbox. This gear set features a T56 style 26-spline 2-piece input shaft. The design provides drivers with instant gear selection and clutch-less shifting capabilities. The ratios are precisely matched to final drive, wheel, and tire sizes, making it ideal for drag racing applications. The SU-6S4GV2DB-GA has undergone rigorous testing and development, proving its ability to handle the extreme demands of motorsport and deliver legendary strength, durability, and reliability. This gear set, along with its final drive, has achieved quarter-mile times in the 7-second range for Subaru STI WRX vehicles, making it a preferred choice for drag racers using Subaru platforms, even with engines producing over 1000hp. The ratios are 3.077 (1st), 1.875 (2nd), 1.350 (3rd), and 0.957 (4th). Features include a T56 26-spline 2-piece input shaft for increased strength, which requires a special clutch.
