4102-391R UDS 1350 Flange Yoke
The 4102-391R is a 1350 series flange yoke manufactured by UDS. It bolts to a companion flange on the transmission, transfer case, or differential output using a 8-bolt pattern on a 3.950-inch bolt circle. The N/A, SERRATED-inch pilot diameter registers the yoke concentrically against the companion flange to minimize runout.
The 8 bolt holes are 0.450-inch diameter on the 3.950-inch bolt circle. The center-U-joint-to-flange-face dimension is 2.375 inches. This 1350 series yoke accepts a 1350 U-joint in the yoke ears — the ear bore is machined specifically for the 1350 cap diameter. Application note: Rectangle Pattern. The 1350 series ranks above 1330 in torque capacity, with a 1.188-inch cap diameter, suited for 3/4-ton and 1-ton trucks, common in Ford Super Duty, GM 2500/3500, and Ram 2500/3500 applications.

Fitment & Installation Notes
Before ordering the 4102-391R, measure the bolt circle diameter and pilot diameter on the companion flange. The bolt circle (3.950") and pilot (N/A, SERRATED") must match exactly. A 1350 U-joint is required — do not install a different-series joint in these ears.
