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

The 3-83-3281X CV flange yoke is the flange-side connection point for constant velocity driveshaft assemblies in 1350 series applications. Unlike a standard flange yoke, it accommodates the ball stud centering mechanism that keeps the CV joint operating at equal velocity through its full angle range. Bolt circle, pilot diameter, and ball stud diameter are all specific to one application.

3-83-3281X Cv Flange Yoke — 1350 Series Ball Stud & Bolt Pattern

The 1350 series covers 3/4-ton trucks — F-250, Ram 2500, Dana 44/60 axles, performance 4x4. The 3-83-3281X CV flange yoke specs: 4.25 bolt circle | 3.125 pilot | 0.5" ball stud | 1.625" CL-to-face. Fits 3R Saginaw applications. The ball stud bore is what makes this a CV-specific part — it's not interchangeable with a standard flange yoke. Ball stud diameter must match your CV head socket exactly. Bolt circle and pilot match your diff or axle flange.

Confirm your driveshaft uses a CV design before ordering a 3-83-3281X CV flange yoke. CV flange yokes aren't interchangeable with standard flange yokes — the geometry is different. If you're converting from a standard u-joint front shaft to a CV setup, the flange yoke is the first part to spec out.
