2-3-12051X Tranny Yoke 1330 Series Hub: 1.500 Splines Count: 26/27 GM

2-3-1205XU UDS 1330 Slip Yoke

The 2-3-1205XU is a 1330 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 26/27-inch diameter with 1.176 splines. The stop shaft on the driveshaft tube must have an identical 26/27-inch diameter and 1.176-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 6.750 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. TH700 / Forged Steel / Black Oxidized / CHROMOLY. The 1330 series ranks above 1310 in torque capacity, with a 1.062-inch cap diameter, suited for 3/4-ton trucks and heavier light-duty applications.

Fitment & Installation Notes

When selecting the 2-3-1205XU, verify the stop shaft spline count and diameter match the 26/27 X 1.176 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
