4802-1242 – Flange Yokes – 1480 Series – Bolt Circle Dia 3.950″ – Bolt Hole Dia 0.480

Replacing a worn or damaged flange yoke starts with getting the right part. The 4802-1242 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1480 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 4802-1242 flange yoke removes both risks.

4802-1242 Flange Yoke — 1480 Series Specifications & Fitment

The 1480 series covers heavy commercial Class 3-4 trucks and Dana heavy applications. The 4802-1242 flange yoke specs: 3.950 bolt circle | 3.150 pilot | 4x0.480 bolt holes | 2.559" 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 4802-1242 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.
