6.5-4-4631-1 – End Yoke – 1810 Series – 2.794″ Splines Dia – 54 Spline

End yoke failures are usually easy to diagnose: cracked ears, worn splines, or corrosion at the cap bores. Whatever the cause, the 6.5-4-4631-1 end yoke is the direct replacement for 1810 series applications. Spline count and shaft diameter both have to match — verify yours before ordering.

6.5-4-4631-1 End Yoke — Spline Specs & 1810 Series Fitment

The 1810 series covers Class 7-8 commercial and heavy industrial equipment. The 6.5-4-4631-1 end yoke specs: 2.794 x 54 spline | 0.000"" hub dia | 5.652" CJ-to-end | 2.750" 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 6.5-4-4631-1 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
