2-2-489 | Flange Yoke 1330 Series , Holes: 4 x 0.438 | Bolt Circle Dia : 3.750 , Pilot: 2.750M 

Replacing a worn or damaged flange yoke starts with getting the right part. The 2-2-489 flange yoke is dimensioned for one bolt circle, one pilot diameter, and one drivetrain series — 1330 series. A mismatched bolt circle means the yoke won't seat flat. A wrong pilot means the driveshaft runs off-center. The 2-2-489 flange yoke removes both risks.

2-2-489 Flange Yoke — 1330 Series Specifications & Fitment

The 1330 series covers light-to-medium duty trucks and GM half-ton platforms. The 2-2-489 flange yoke specs: 3.750 bolt circle | 2.750 pilot | 4x0.438 bolt holes | 1.562" CJ-to-flat. REQUIRES A 1330 SERIES UNIVERSAL JOINT. 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 2-2-489 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.
