3-83-3281X CV Flange Yoke 1350 Fits 3R APP 4.250 Bolt Circle Dia

3-83-3281X UDS 1350 Series CV Flange Yoke 3R Saginaw Application

The 3-83-3281X is a 1350 series CV (constant velocity) flange yoke manufactured by UDS, designed for 3R Saginaw applications. It carries a 4.25" bolt circle diameter with 0.465" bolt hole diameter and a 3.125" pilot diameter (female pilot type). The ball stud diameter is 0.5", and the CL-to-face dimension is 1.625". This is an LD (light duty) class unit.

When fitting the 3-83-3281X, verify the transfer case or transmission output flange uses a 4.25" bolt circle with 0.465" fastener holes and a 3.125" female pilot. The female pilot type requires a matching male pilot protrusion on the companion flange — confirm pilot type compatibility before installation. The 0.500" ball stud dimension is specific to the CV centering socket on the companion yoke.

The 3-83-3281X is rated LD (light duty) within the 1350 series; this designates it for standard, non-high-output 3R Saginaw transfer case applications. The 1350 series provides higher torque capacity than 1310 or 1330. The CV joint design eliminates the operating angle limitations of a conventional U-joint at the output end of the transfer case, making the 3-83-3281X suitable for lifted or high-articulation vehicle configurations in this application.
