3-4-4421-1X End Yoke 1480 , Spline:s 1.500 x 10 , Hub Dia: 1.938 , Center U joint To End: 4.030

The 3-4-4421-1X end yoke connects the driveshaft end to the axle or transfer case output shaft via a splined bore. Spline count and diameter are the critical dimensions — a mismatch here means the yoke either won't engage the shaft or will engage loosely and spin out under load. The 3-4-4421-1X end yoke is machined to one specific spline specification for 1480 series applications.

3-4-4421-1X End Yoke — Spline Specs & 1480 Series Fitment

The 1480 series covers heavy commercial Class 3-4 trucks and Dana heavy applications. The 3-4-4421-1X end yoke specs: 1.500" x 10 spline | 1.938" hub dia | 4.031" CJ-to-end | 2.000" bore. Hub diameter is the outer dimension that clears the axle housing or T-case bore. CJ-to-end determines how the u-joint positions relative to the flange or seal surface. Count the splines on your output shaft — don't go by the vehicle model alone. Axle swaps and rebuilds can change the spline count from the original. The 3-4-4421-1X end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
