The Hub Bearing Kit # BK2-100 is the standard size used on most 3,500lb trailer axles. There are a few manufacturers who used different size components. The best way to verify is by disassembling one of your hubs to check the part numbers on your bearings and seal. Or if your axle has a manufacturer tag on the axle we may be able to check the parts information with the axle manufacturer.
