3-28-417 Tube Weld Yoke 1350 , Fits: 4.000 X 0.083 Tube, Butt: 3.844 CL To Weld: 1.688 Inch

3-28-417 UDS 1350 Series Weld Tube Yoke

The 3-28-417 is a UDS 1350 series steel weld tube yoke built for a 4.000-inch OD x 0.083-inch wall driveshaft tube. The butt diameter measures 3.844 inches and the centerline-to-weld dimension is 1.688 inches. This yoke is welded onto the tube end and mates with a 1350 series U-joint, making it appropriate for larger-diameter driveshafts found in heavy truck and performance applications.

Specifications

• Part Number: 3-28-417
• Brand: UDS
• Series: 1350
• Material: Steel
• Tube Diameter x Wall: 4.000 in x 0.083 in
• Butt Diameter: 3.844 in
• Center U-Joint to Weld: 1.688 in

When fitting the 3-28-417, the 4.000-inch tube OD and 0.083-inch wall specification are critical — substituting a thinner or thicker wall tube will produce an incorrect fit at the butt diameter. The 3.844-inch butt diameter pilots into the tube bore; verify the cut face is square and the tube is not out-of-round before welding. A 1.688-inch CL-to-weld is compact; account for this in overall driveshaft length calculations.

The 3-28-417 is designed for the 1350 series U-joint interface. At a 4-inch tube diameter, this yoke is typically associated with high-torque applications where driveshaft diameter was increased to reduce critical speed. Confirm the U-joint series matches throughout the assembly before installing.
