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.
Contact your local driveline shop for availability. If you need assistance finding a shop, or if you would like to become a distributor, fill out the form and a Sonnax driveline product specialist will contact you.
Measure bolt circle diameter as well as pinion and output flange bolt hole diameters to determine if these yokes will fit your build.
