2603-25 – Transmission Yokes – 7260 Series – 23/25 X 1.083 Splines – 1.495″ Hub Dia

2603-25 UDS 7260 Slip Yoke

The 2603-25 is a 7260 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 23/25-inch diameter with 1.083 splines. The stop shaft on the driveshaft tube must have an identical 23/25-inch diameter and 1.083-spline profile — a mismatch in either count or diameter means the yoke will not engage. The centerline-to-end dimension is 6.000 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. Mazda, Some Early Mustangs. The 7260 series uses 1.062-inch cap diameter U-joints and is standard for light-duty and medium-duty passenger vehicle applications.

Fitment & Installation Notes

When selecting the 2603-25, verify the stop shaft spline count and diameter match the 23/25 X 1.083 specification. Inspect the stop shaft for wear or damage; a worn shaft will produce lash even with a new yoke.
