Sonnax forged chromoly performance slip yoke T3-3-2491HP is an excellent upgrade over factory style transmission yokes. This affordable yoke uses 1350 series u-joints, and fits several applications, including most T56, FMX, C6, Tremec, and ZF 5-speed 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.
