Since the bump stops are in the stock location, you will bottom out at the same place as stock. When you bottom out or articulate fully, the tires will rub the plastic fender.

When looking at the axle, the bolt will be at the bottom. The nut is usually welded to the bolt, but you can still take the bolt out. I like to take the stops out and put a washer in as a shim. If you don't use the same length addition to each side, one side will rub and the other won't.
