Achieve the proper height for your tow bar setup with the Blue Ox Towbar Drop or Rise Receiver Adapter. This hitch adapter lets you adjust the height of your tow bar to be level for towing. With this adapter, you can rise 4 inches or drop 4 inches to make up for the height difference between your RV and the towed vehicle. Ultimately, this adapter makes up for the height difference between RV's hitch and towed vehicle's base plates. Constructed out of steel, this adapter is built durable. And it has a powder-coated finish to resist rusting and corrosion. This rise or drop adapter is designed for flat towing only and it should only be used with tow bars. Keep your towed vehicle at the same level as your RV with the Blue Ox Towbar Drop or Rise Receiver Adapter.
