UDS T3-2-1579A 1350 Series Aluminum Flange Yoke – 4.25″ Bolt Circle, 2.000″ Pilot Dia, Compatible with Ford F-150 & Expedition

Precision yoke geometry defines the balance potential of any driveshaft assembly. The T3-2-1579AU flange yoke from UDS is engineered to Series 1350 dimensional tolerances, with a 2.000" pilot diameter and 4.25" bolt circle, providing the accurate centering and clamping force needed to maintain a balanced shaft over the full speed range.

Technical Specifications -- T3-2-1579AU

Dimensional Standards

The T3-2-1579AU is compatible with all Series 1350 companion flanges and yoke bores meeting the published dimensional standard. The 2.000" pilot diameter is a precision ground fit that centers the yoke concentrically on the mating component. Four bolt holes on a 4.25" bolt circle accept standard Series 1350 fasteners. Verify that the mating component -- whether a differential pinion flange, transfer case output, or transmission tailshaft -- specifies Series 1350 to ensure correct geometry.

Balancing & Service Notes

Install the T3-2-1579AU with new fasteners torqued to the vehicle or equipment manufacturer's flange bolt specification. Clean the mating pilot bore and flange face before assembly to ensure full contact. Apply anti-seize compound to flange bolt threads if operating in a corrosive environment. Inspect the yoke ears and snap-ring grooves for burrs after installation of the U-joint cross.

• Use a torque wrench -- do not impact-gun flange bolts to final torque
• Re-torque flange bolts after the first 100 miles in service
• Balance the completed shaft assembly after yoke replacement on high-speed applications
