Will the park assist sensors work with the cutouts pre-cut?

Yes. The sensor openings are sized and positioned to match factory specs—your sensors will function immediately without reaming or adjustment.

Does this cover require painting before installation?

That depends on your preference. You can install it as-is for a primer-ready look or paint it to match your truck's color beforehand. Either way works—just test-fit before finalizing paint if you're concerned about gaps.

Will I need new hardware to mount this?

Check your truck's existing fasteners first. You're reusing the factory bolt holes, so odds are good your hardware is already there. Bring a jack and socket set and confirm before you order extras.
