T3-3-8251HP – Transmission Yokes – 1350 Series – 1.500″ Hub Dia – Center U Joint To End 6.500

T3-3-8251HP UDS 1350 Slip Yoke

The T3-3-8251HP is a 1350 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 27/28-inch diameter with 1.220 splines. The stop shaft on the driveshaft tube must have an identical 27/28-inch diameter and 1.220-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 6.500 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. C4 / Forged Steel / Black Oxidized / CHROMOLY. The 1350 series ranks above 1330 in torque capacity, with a 1.188-inch cap diameter, suited for 3/4-ton and 1-ton trucks, common in Ford Super Duty, GM 2500/3500, and Ram 2500/3500 applications.

Fitment & Installation Notes

When selecting the T3-3-8251HP, verify the stop shaft spline count and diameter match the 27/28 X 1.220 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
