Tow Bar Base Plate Adapter Header
If you're flat towing your vehicle, it's best to go with a base plate and tow bar from the same manufacturer for the sake of easy compatibility. However, if you do decide to mix and match, you can use an adapter to connect your components. To determine which adapter you need, choose your tow bar manufacturer and model below, then use the corresponding chart to figure out which adapter part number you need.
