Sonnax forged chromoly performance slip yoke T3-3-2491S is an excellent upgrade over factory style transmission yokes. This yoke utilizes 1350 series u-joints and is made for use with Tremec Magnum-F 6-speed transmissions. These high performance slip yokes deliver superior strength and durability for high horsepower and torque capacity applications — whether on the street, at the strip or on the circle 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.
