IAG Performance Chromoly Transfer Gears For 1.1:1 Transmission (2006-2020 Impreza WRX STI, WRX STI) - IAG-DRV-1010
The IAG Chromoly Transfer Gear Set is specifically engineered to strengthen the weak points in the STI 6 speed transmission. When a powerful STI launches aggressively at the track the output shaft progressively twists and weakens. After multiple launches, the output shaft breaks where the driveshaft yoke connects. IAG's upgraded transfer gear set is capable of handling these immense loads by improving the gear material and redesigning the parts at the weakest points. The gears are manufactured from Chromoly, which is known for its improved hardness and strength. The output shaft diameter was increased and the splines were enlarged and lengthened then matched to an upgraded Spicer yoke designed to mate to an aftermarket performance driveshaft. The IAG transfer gears were tested on Subaru drag vehicles producing over 1200 WHP/800 WTQ at 3000+ LBS. This transfer gear set is 1.1:1 for the 2007-2021 STI ONLY!
Increased strength to prevent breakage during drag launches
