Sonnax T3-3-5431HP forged chromoly performance slip yoke is an excellent upgrade over factory style transfer case yokes, adding strength and durability at an affordable price.
The T3-3-5431HP uses 1350 series u-joints, for Ford Bronco, F-150, F-250 and F-350 with 31-spline output BorgWarner transfer cases. These high performance slip yokes deliver superior strength and durability for high horsepower and torque capacity applications, from street car, to street rod, drag strip, to dirt oval track.
Some slip yokes have missing splines. To verify spline count, always count the splines on the transmission output shaft. A slip yoke counterbore is a short lead without spline in the end of the yoke.
