3502-1619 Flange Yoke 1350 Series, Ford 3-2-1619 Bolt Circle Diameter: 4.250 Pilot: 2.000 Inch Bolt Holes: 0.410 Threaded

Replacing a worn or damaged flange yoke starts with getting the right part. The 3502-1619 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1350 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 3502-1619 flange yoke removes both risks.

3502-1619 Flange Yoke — 1350 Series Specifications & Fitment

The 1350 series covers 3/4-ton trucks — F-250, Ram 2500, Dana 44/60 axles, performance 4x4. The 3502-1619 flange yoke specs: 4.250 bolt circle | 2.000 pilot | 4x0.470 bolt holes | 1.625" 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 3502-1619 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.
