This is a complete hub and drum assembly that replaces the brake hub on a trailer axle. It is made for 6,000 lb axles with a #42 spindle and uses a 6 on 5.5in bolt pattern with 1/2-inch wheel studs. The bearings are pre-greased, and the races are already installed.
It works with 12in x 2in trailer brakes and with both grease and E-Z Lube (zerk-lube) axle systems. It replaces the hub on utility, equipment, cargo, livestock and flatbed trailers. The assembly comes retail boxed.
