Do I need to drill new fog light holes, or are cutouts pre-made?

The bumper ships as a solid panel. You'll need to mark and cut fog light openings to match your vehicle's lamp location and size. Use the OEM fog light position as your reference point before cutting.

Will this bumper cover my factory bumper sensor holes?

The three-piece design covers most of the lower bumper area. If your vehicle has factory sensors in the bumper, measure their exact position and mark those cutouts before final installation. Refer to your vehicle's service manual for sensor locations.

Does the wide body design work with the factory lower valance, or will I need a new one?

The extended side sections of this bumper will sit wider than the factory valance. You can modify the existing valance to fit the new bumper profile, or source an aftermarket lower valance designed for wide-body applications. Plan your lower panel fitment before final install.
