6-2-739 Flange Yoke1710 Series ,Holes: 8 x 0.438 Holes, Bolts Circle Diameter: 7.250, Pilot: 7.750M

The 6-2-739 flange yoke mounts to the companion flange or axle housing and carries the driveshaft end u-joint. It's not a universal part — the bolt circle, pilot diameter, and series are all specific. Vibration that tracks with vehicle speed and stays consistent under load often starts right here, at a worn or mis-seated flange yoke. The 6-2-739 flange yoke is the correct replacement.

6-2-739 Flange Yoke — 1710 Series Specifications & Fitment

The 1710 series covers Class 6-7 vocational and industrial drivetrains. The 6-2-739 flange yoke specs: 7.250 bolt circle | 7.750 pilot | 8x0.438 bolt holes | 3.000" 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 6-2-739 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.
