STOP, before you buy, if you are not sure what your axle, hub or bearing size is, you MUST measure. I am sorry, but the axle manufactures have not been very consistent. Many use the same hub for several axle sizes. All inner bearings are the same, but the outer bearing (closest to the nut) may be different. You must confirm your outer bearing either by looking at the number, or measuring the outer diameter of the outer race. Also, the inner grease seal may be 2.125" or 2.25", if you need the 2.125". please specify
Fits standard #42 axle spindle used on 6000# axles (If you are not sure, see chart below, 7th and 8th lines down from top):
