Helpful Expert Reply:

The bearing kit you need for your 3500 lb axle and seal number you gave is the Bearing Kit # BK2-100. This kit will give you the seal, inner bearing and race, outer bearing and race, washer and cotter pin for one hub. So for your tandem axle trailer, you will need 4 of these kits.
