This 5 Bolt Hot-Dipped Galvanized Hub kit will include 2 hubs, bearings, seals, lug nuts and dust caps - everything you need to get your trailer on the road again! Fits 2,500 pound trailer axles with straight spindles, but to know if this hub is the right fit for your setup you would want to check the size your current bearings and make sure that they match up with the 1 1/16" bearings that these hubs come with as well as knowing that you have a standard length spindle. This Hub fits standard length spindles, not "short spindles".
