3102-361 – Flange Yokes – 1310 Series – Bolt Circle Dia 3.543″ – Pilot Dia 2.362, M

The 3102-361 flange yoke is the direct bolt-on connection between your 1310 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 3102-361 flange yoke is machined to one specific set of dimensions, and those dimensions have to match your axle flange exactly.

3102-361 Flange Yoke — 1310 Series Specifications & Fitment

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 3102-361 flange yoke specs: 3.543 bolt circle | 2.362 pilot | 4x0.410 bolt holes | 1.685" 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 3102-361 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.
