My 2020 Ford F-150 didn’t come with rear wheel well guards straight from the factory. Without these wheel well guards, the wheel well area can take a lot of abuse from dirt, rocks, etc. kicking up from the rear tires. In addition to the added protection from the wheel well guards, the rear wheel well looks a lot better and has a more finished look to it. It looks even better on lighter color vehicles when light-colored wheel well area is an eye sore.
