There are 2 possible bearing kit options for your 7K Dexter Axles and it all depends on what grease seal inner diameter you need:

- Bearing Kit # BK3-210 (2.125" ID)
- Bearing Kit # BK3-200 (2.250" ID)

Aside from that both kits have the same bearings so it really does boil down to the size of the grease seal. Just pull a hub and either measure the inner diameter of the grease seal or the diameter of the spindle where the seal rides and that will tell you which kit you need.
