This evening saw a small F150 project in adding the optional rear wheel well liners. While I’m sure they make exceedingly little actual functional difference, they do cover more area than the painted area of the wheel wells and I like the more finished look.
If I had my way, these would have been standard on every truck for the last 20 years. As it is, the fit and hardware was as expected for a factory part, and they only took a few minutes to put on each side. Removing and installing each rear tire and placing a jack stand took longer than putting the new parts on.
