Curt Bearing Protectors

Acting like a cap for your wheel bearings, CURT bearing protectors offer two essential benefits for your trailer. First, they provide a reservoir of grease to lubricate your wheels and keep them turning smoothly mile after mile. Second, they cover the bearings so that mud, rain, road grime and other threats to their function are kept out. A bad wheel bearing can start out as a mere annoyance, but before long, it can turn into a huge problem. With CURT wheel bearing protectors, you can ensure that your wheels keep turning, quiet as a mouse. They come with plastic dust covers that fit over the end of the protector for even more defense against the elements. This set of bearing protectors features a 1.98" hub diameter.
