3526-403A ALUMINUM WELD YOKE 1350 Series , Fits 4.000×0.083 Tube , HD T6061

3526-403A UDS 1350 Series Aluminum Weld Yoke 4.000x0.083 Tube T6061

The 3526-403A is a 1350 series aluminum weld yoke manufactured by UDS from T6061 aluminum alloy, designed to fit 4.000" OD x 0.083" wall driveshaft tube. The butt diameter measures 3.855" and the center U-joint to weld distance is 2.125". T6061 aluminum construction reduces rotating mass compared to steel weld yokes while maintaining structural integrity in light-duty to medium-duty 1350 series applications.

Specifications

• Part Number: 3526-403A
• Brand: UDS
• Series: 1350
• Material: Aluminum (T6061)
• Tube Dia x Wall: 4.000" x 0.083"
• Butt Diameter: 3.855"
• Center U-Joint to Weld: 2.125"

When fitting the 3526-403A, the tube OD must be exactly 4.000" and wall thickness 0.083" — the 3.855" butt diameter provides the shoulder stop for tube seating prior to welding. The 2.125" center U-joint to weld dimension establishes the U-joint working position relative to the weld joint; confirm this fits within the driveline envelope. Aluminum yokes require attention to weld procedure — use appropriate filler rod and preheat for T6061 to prevent heat-affected zone cracking. The 3526-403A mates with standard 1350 series U-joints; confirm cap diameter and width compatibility at both the yoke ears and the mating end yoke or slip yoke before assembly. Aluminum construction makes the 3526-403A unsuitable for applications that regularly see U-joint angles exceeding 1350 series limits or high-impact torque spikes. Verify tube OD and wall spec against the shaft being modified before welding.
