211229X – Cv Flange Yokes – 1310 Series – Bolt Hole Dia 484″ – Bolt Circle Dia 3.500

The 211229X CV flange yoke is the flange-side connection point for constant velocity driveshaft assemblies in 1310 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.

211229X Cv Flange Yoke — 1310 Series Ball Stud & Bolt Pattern

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 211229X CV flange yoke specs: 3.500 bolt circle | 1.625 pilot | 0.5" ball stud | 1.625" CL-to-face. Socket OD 1.394. 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 211229X 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.
