3502-0163U Flange Yoke — 1350 series, 3.937 bolt circle | 0.630 pilot | 3×0.480 bolt holes | 3.000″ CJ-to-flat. Proven bolt-on replacement. Verify bolt circle and pilot before ordering.
Full Description
The 3502-0163U flange yoke is the direct bolt-on connection between your 1350 series driveshaft and the differential or axle housing flange. Bolt circle and pilot diameter are the two specs that determine whether this part fits — everything else is secondary. The 3502-0163U flange yoke is machined to one specific set of dimensions, and those dimensions have to match your axle flange exactly.
3502-0163U 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 3502-0163U flange yoke specs: 3.937 bolt circle | 0.630 pilot | 3x0.480 bolt holes | 3.000" CJ-to-flat. Aluminum 6061-T6 Tri Flange, 100mm (3.937) bolt circle, Hole to hole 3.409", 16mm nose hole, 12mm bolt holes. 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 3502-0163U 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.
