4103-431 – Transmission Yokes – 1410 Series – 43 X 1.654 Splines – 2.457″ Hub Dia

The 4103-431 transmission yoke is the connection between the gearbox tailshaft and the front of the driveshaft. It splines onto the transmission output shaft and carries the front u-joint of the driveshaft. For 1410 series applications, the spline count and hub diameter are the two specs that determine whether this part fits your tailshaft correctly.

4103-431 Transmission Yoke — 1410 Series Specs & Tailshaft Fit

The 1410 series covers HD trucks — F-250/350/450, Ram 2500/3500, Dana 60/70 axles. The 4103-431 transmission yoke specs: 43 X 1.654 spline | 2.457" hub | 9.153" CJ-to-end. Hub diameter determines engagement depth on the tailshaft — if the hub is too short, the splines don't fully engage. CJ-to-end affects driveshaft working length.

After a transmission rebuild or swap, confirm the tailshaft spline count hasn't changed before installing the 4103-431 transmission yoke. Not all 1410 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
