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. T3-3-5431HP uses 1350 series u-joints for transmissions 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.
Measure OE slip yoke with a precision tool to determine which Sonnax yoke you need. Length, journal size and U-joint series are critical dimensions requiring accurate measurements.
*U-joint bores in yoke will be slightly larger than the actual U-joint dimensions given in the chart below.
