Flange Yoke
Part No. T3-2-1869

Ford Super Duty (Rear)

OE Part No. 3C3Z-4865-CA

Sonnax flange yoke T3-2-1869 connects the rear of the driveshaft to the differential pinion yoke in most '05-'16 Ford F-250, F-350, F-450 and F-550 Super Duty models. While the OEM uses cast steel yokes in this position, the Sonnax billet aluminum yoke is just as strong — while providing rotational weight savings. Coupling this yoke with an aluminum driveshaft and output (front) flange yoke T3-2-1719 is the best way to dramatically lower rotating mass, without sacrificing strength or performance.

Sonnax flange yoke T3-2-1869 is a custom part and may fit more models than noted above. Measure flange dimensions, flange bolt holes and bolt circle diameter to determine if this yoke is appropriate for your build.
