Full Description
The 3503-310 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.
3503-310 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 3503-310 transmission yoke specs: 30/31 X 1.391 spline | 1.685" hub | 8.250" CJ-to-end. Compatible with: Ford E4OD, 4R100. 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 3503-310 transmission yoke. Not all 1350 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
