1203-24S – Transmission Yokes – 1251 Series – 22/24 X 0.995 Splines – 1.375″ Hub Dia

1203-24S UDS 1251 Slip Yoke

The 1203-24S is a 1251 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 22/24-inch diameter with 0.995 splines. The stop shaft on the driveshaft tube must have an identical 22/24-inch diameter and 0.995-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 4.750 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. Nissan. The 1251 series is designed for the specified application range.

Fitment & Installation Notes

When selecting the 1203-24S, verify the stop shaft spline count and diameter match the 22/24 X 0.995 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
