3503-231 – Transmission Yokes – 1350 Series – 23 X 1.200 Splines – 1.575″ Hub Dia

The 3503-231 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 1350 series applications, the spline count and hub diameter are the two specs that determine whether this part fits your tailshaft correctly.

3503-231 Transmission Yoke — 1350 Series Specs & Tailshaft Fit

The 1350 series covers 3/4-ton trucks — F-250, Ram 2500, Dana 44/60 axles, performance 4x4. The 3503-231 transmission yoke specs: 23 X 1.200 spline | 1.575" hub | 7.106" CJ-to-end. Compatible with: TOYOTA. 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 3503-231 transmission yoke. Not all 1350 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
