Sonnax T3-3-5551HP forged chromoly performance slip yoke is an excellent upgrade over factory style transmission yokes, adding strength and durability at an affordable price. The T3-3-5551HP uses 1350 series u-joints and fits a variety of applications, including those listed here. It can be counterbored for truck-style TH400 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.
