Dexter Hub and Rotor Kit K08-440-05, 6000 lb Capacity, 6 on 5.5 Inch, Cupped and Studded, Zinc

This Dexter Hub and Rotor Kit, part number K08-440-05, is a complete 6,000 lb capacity hub and rotor assembly built for trailer axles using a 6 on 5.5 inch bolt pattern. The kit is supplied cupped, meaning the bearing cups are pre-installed in the hub, and studded, meaning the wheel studs are already pressed into place, so it is ready to accept bearings, seal, and wheel without additional pressing work at installation. The rotor and hub carry a zinc finish for corrosion resistance in the wet, salt-exposed environment typical of trailer and marine trailer service.

This assembly is intended as a direct hub and rotor replacement or upgrade for disc brake trailer axles rated to the matching 6,000 lb capacity and 6 on 5.5 inch bolt circle. It is sold as the hub and rotor unit itself; bearings, races, seals, and hardware not listed in the specifications below are not included.
