Description
3102-391 Flange Yoke — 1310 series, 3.386 bolt circle | 3.937 pilot | 6×0.415 bolt holes | 2.592″ CJ-to-flat. Professional bolt-on replacement. Verify bolt circle and pilot before ordering.
Full Description
Replacing a worn or damaged flange yoke starts with getting the right part. The 3102-391 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1310 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 3102-391 flange yoke removes both risks.
3102-391 Flange Yoke — 1310 Series Specifications & Fitment
The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 3102-391 flange yoke specs: 3.386 bolt circle | 3.937 pilot | 6x0.415 bolt holes | 2.592" 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 3102-391 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.
