Do I need to remove the OEM bumper before installing this?

Yes. Remove your factory bumper by unbolting it from the core support and frame rails, then transfer the hardware to the new cover. The mounting points align with your vehicle's existing structure.

What prep work is needed before painting?

Sand and prep the surface with fine-grit sandpaper to create a smooth base for your chosen topcoat. Wipe down with a tack cloth to remove all dust before applying primer and paint.

Are the fog light cutouts already sized, or will I need to modify them?

Check the existing fog hole openings against your lighting setup before final installation. You may need to adjust the openings to match your specific fog light housings or aftermarket lights.
