1102-191 – Flange Yokes – ATV Series – Bolt Circle Dia 3.200″ – Bolt Hole Dia 0.411

The 1102-191 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 1102-191 flange yoke is the correct replacement.

1102-191 Flange Yoke — ATV Series Specifications & Fitment

The 1102-191 flange yoke specs: 3.200 bolt circle | 1.968 pilot | 4x0.411 bolt holes | 1.125" 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 1102-191 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.
