This Armor Flex cover is solid. Took me under an hour to install and it looks amazing on my Lightning. It’s held up through heavy rain and snow—no leaks, no rattles.

Love the matte black finish and how flush it sits. It doesn’t rattle or shift, even on rough roads. Definitely worth the upgrade for my 2022 F-150.
