Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is an E-Z Lube style hub, which means it has a grease fitting accessible through the hub cap to make bearing lubrication simple without taking the hub apart. The kit includes the hub, bearings, races, seal, grease cap, and lug nuts, so you have everything to replace a worn or damaged hub on your trailer. You would typically replace this if your existing hub is damaged, has a bearing failure, or if you are doing a complete axle end rebuild.
