On the linked page you can see our hub/drum assemblies that use a 6 on 5-1/2 Inch bolt pattern and a # 25580 inner bearing. Please note these are for axles rated for 5200- or 6000-lbs. Kit # 8-201-9UC3-EZ uses your same inner bearing, outer bearing # 15123, which has the same 1.250-inch inner diameter as yours, and that works with a seal whose inner diameter is 2.125-inches. This kit should work fine for you.

The linked article and video on bearings may be of interest to you.
