4103-322 Transmission Yoke Chevy 1410 Series 31/32 Splines | 3-3-01646X

4103-322 UDS 1410 Slip Yoke

The 4103-322 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 31/32-inch diameter with 1.378 splines. The stop shaft on the driveshaft tube must have an identical 31/32-inch diameter and 1.378-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 8.070 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. Nickel Plated. 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 4103-322, verify the stop shaft spline count and diameter match the 31/32 X 1.378 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
