6-4-7181-1X – End Yoke – 46 x 2.390″ Splines – 5.391″ Cj To End – 3.250″ Hub Dia – Partn Number 6-4-7181X

The 6-4-7181X end yoke slides onto the axle or transfer case output shaft and holds the u-joint cross at the end of the driveshaft. It's a spline-specific fit for 1710 series applications — the spline count determines engagement, the hub diameter determines outer clearance, and the series determines which u-joint cross the ears accept.

6-4-7181X End Yoke — Spline Specs & 1710 Series Fitment

The 1710 series covers Class 6-7 vocational and industrial drivetrains. The 6-4-7181X end yoke specs: 2.390" x 46 spline | 3.250"" hub dia | 5.391" CJ-to-end | 2.328 bore. Strap/bearing-plate retention provides more clamping force than snap rings — preferred for high-torque and heavy-duty use. 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 6-4-7181X end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
