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

4103-431 UDS 1410 Slip Yoke

The 4103-431 is a 1410 series slip yoke manufactured by UDS. The slip yoke slides over the stop shaft — the splined stub welded onto the front section of the driveshaft tube — and telescopes in and out as the suspension cycles. This allows the driveshaft to change working length without binding.

The spline bore is 43-inch diameter with 1.654 splines. The stop shaft on the driveshaft tube must have an identical 43-inch diameter and 1.654-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 9.153 inches, measured from the U-joint centerline to the open end of the spline bore. This controls minimum engagement depth under full suspension droop — ensure sufficient spline overlap remains at maximum driveshaft extension. The 1410 series ranks above 1350 in torque capacity, with a 1.188-inch cap diameter, suited for 1-ton and heavy-duty pickup trucks.

Fitment & Installation Notes

When selecting the 4103-431, verify the stop shaft spline count and diameter match the 43 X 1.654 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
