The 3103-320 Transmission Yoke is specifically engineered for GM transmissions, particularly those with a 32 spline output shaft, such as the Turbo 400 and TH-400. If you’re experiencing vibrations or driveline issues, this yoke could be the solution you need. A worn or damaged yoke can lead to misalignment, excessive play, and ultimately, failure of the U-joint or other driveline components.

Measuring 5.500 inches from the center U-joint to the end, this yoke ensures proper engagement and alignment. The 1.886″ hub diameter and 31/32 X 1.397 splines are critical for compatibility with the 1310 series U-joints, which are widely used in performance and heavy-duty applications. If you notice a clunking sound during acceleration or deceleration, it may indicate that the yoke is not engaging properly due to wear or damage.

• 5.500″ Length from center U-joint to end
• 1.886″ Hub Diameter for secure fit
• 31/32 X 1.397 Splines for 1310 Series U-joints
• Designed for Short TH400 applications
• Check spline engagement depth during installation

Replacing a worn yoke with the 3103-320 restores proper function and alignment, ensuring a smooth and reliable driveline operation. Always verify the spline count and series to prevent compatibility issues.
