Sonnax T3-3-4281HP forged chromoly performance slip yoke is an excellent upgrade over factory style transmission yokes, adding strength and durability at an affordable price. The T3-3-4281HP uses 1350 series u-joints, and fits several applications, including most 4L60, 700R4 and TH350 transmissions. 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.
