3502-1068 – Flange Yokes – 1350 Series – Bolt Circle Dia 3.300″ – Pilot Dia 3.937, OD

The 3502-1068 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 3502-1068 flange yoke is machined to one specific set of dimensions, and those dimensions have to match your axle flange exactly.

3502-1068 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 3502-1068 flange yoke specs: 3.300 bolt circle | 3.937 pilot | 6x0.315 bolt holes | 2.598" 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 3502-1068 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.
