2-2-329 – Flange Yokes – 1310 Series – Bolt Circle Dia 3.125″ – Pilot Dia 2.375, M

Replacing a worn or damaged flange yoke starts with getting the right part. The 2-2-0329 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1310 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 2-2-0329 flange yoke removes both risks.

2-2-0329 Flange Yoke — 1310 Series Specifications & Fitment

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 2-2-0329 flange yoke specs: 3.125 bolt circle | 2.375 pilot | 4x0.375 bolt holes | 1.375" CJ-to-flat. Pilot diameter is what centers the yoke on the companion flange — that dimension must match exactly or the driveshaft will run off-center at speed. Bolt circle determines your hole pattern match.

Before ordering the 2-2-0329 flange yoke, measure your diff flange bolt circle and pilot diameter directly. Don't rely on series designation alone — after an axle swap, the flange dimensions may differ from the original factory spec. Brand: UDS. Verify, then order.
