1202-255 – Flange Yokes – 1251 Series – Bolt Circle Dia 3.750″ – Pilot Dia 2.559-M

Replacing a worn or damaged flange yoke starts with getting the right part. The 1202-255 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1251 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 1202-255 flange yoke removes both risks.

1202-255 Flange Yoke — 1251 Series Specifications & Fitment

The 1202-255 flange yoke specs: 3.750 bolt circle | 2.559-M pilot | 4x0.406 bolt holes | 1.750" 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 1202-255 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.
