UDS 6.5-4-4571X End Yoke – Series 1810 – BP Style

The 6.5-4-4571XU 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 1810 series applications — the spline count determines engagement, the hub diameter determines outer clearance, and the series determines which u-joint cross the ears accept.

6.5-4-4571Xu End Yoke — Spline Specs & 1810 Series Fitment

The 1810 series covers Class 7-8 commercial and heavy industrial equipment. The 6.5-4-4571XU end yoke specs: 2.274 x 44 spline | 3.000"" hub dia | 5.250"" CJ-to-end | 2.500" bore. 1810BP. 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 6.5-4-4571XU end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
