4103-342 – Transmission Yokes – 1410 Series – 33/34 X 1.551 Splines – 2.086″ Hub Dia

The 4103-342 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.

4103-342 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 4103-342 transmission yoke specs: 33/34 X 1.551 spline | 2.086" hub | 8.110" CJ-to-end. Compatible with: Nickel Plated. 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 4103-342 transmission yoke. Not all 1410 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
