T3-2-1579AU UDS 1350 Series 4-Bolt Aluminum Flange Yoke — Ford F-150 and Expedition

The T3-2-1579AU is a 1350 series 4-bolt flange yoke manufactured by UDS from 6061-T6 forged aluminum, noted as approximately 47% lighter than a comparable steel flange yoke. It is compatible with Ford F-150 and Expedition applications. The pilot diameter is 2.000 inches, the bolt circle diameter is 4.250 inches, and the bolt hole diameter is 0.500 inches with 4 holes. The CJ-to-flat dimension is 1.625 inches.

When fitting the T3-2-1579AU, confirm the Ford F-150 or Expedition differential companion flange uses a 2.000-inch pilot and a 4.250-inch bolt circle with 4 x 0.500-inch holes. The 1.625-inch CJ-to-flat dimension affects the driveshaft installed length — account for this offset in length calculations when specifying a replacement driveshaft.

The T3-2-1579AU is forged from 6061-T6 aluminum, which provides the weight reduction advantage noted in the product specs. The 1350 series U-joint interface is appropriate for F-150 and Expedition driveline torque loads. Confirm both the pilot diameter and bolt circle before ordering — the 4.250-inch bolt circle on this yoke differs from the 3.500-inch used on the T3-2-949A (Mustang application).
