3502-1859 Flange Yoke — 1350 series, 4.750 bolt circle | 2.953 pilot | 4×0.500 bolt holes | 1.750″ CJ-to-flat. Professional bolt-on replacement. Verify bolt circle and pilot before ordering.
Full Description
When a 1350 series flange yoke fails, the symptoms show up fast: driveline clunk under acceleration, vibration that doesn't go away with speed changes, or visible play at the diff flange. The 3502-1859 flange yoke is the spec-correct replacement — correct bolt circle, correct pilot, correct series. Dimension confirmation before ordering is still the right call.
3502-1859 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 3502-1859 flange yoke specs: 4.750 bolt circle | 2.953 pilot | 4x0.500 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 3502-1859 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.
