3103-281 – Transmission Yokes – 1310 Series – 27/28 X 1.220 Splines – 1.600″ Hub Dia

The 3103-281 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 1310 series applications, the spline count and hub diameter are the two specs that determine whether this part fits your tailshaft correctly.

3103-281 Transmission Yoke — 1310 Series Specs & Tailshaft Fit

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 3103-281 transmission yoke specs: 27/28 X 1.220 spline | 1.600" hub | 7.375" 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 3103-281 transmission yoke. Not all 1310 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
