Description
3502-0145U Flange Yoke — 1350 series, 4.134 bolt circle | 0.551 pilot | 6×0.559 bolt holes | 3.000″ CJ-to-flat. Complete bolt-on replacement. Verify bolt circle and pilot before ordering.
Replacing a worn or damaged flange yoke starts with getting the right part. The 3502-0145U flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1350 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 3502-0145U flange yoke removes both risks.
3502-0145U 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 3502-0145U flange yoke specs: 4.134 bolt circle | 0.551 pilot | 6x0.559 bolt holes | 3.000" CJ-to-flat. Aluminum 6061-T6 Tri Flange, 105mm (4.134) and 110mm (4.331) bolt circle spacing, 14mm bolt holes, 14mm nose hole, GM apps. Hole to hole: 105mm BC = 3.580", 110mm BC = 3.750". 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 3502-0145U 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.
