Do I need to drill or modify my truck to install this?

No drilling needed. This cover mounts directly at your factory bumper attachment points. The park assist sensor cutout is already in place.

Does this cover work with aftermarket park assist systems?

This cover is designed specifically for factory park assist sensors. If you run a non-OEM system, test-fit first to confirm sensor placement lines up with the cutout.

What prep work do I need before painting?

Sand the primer finish lightly to key the surface, clean off dust, and apply your base and clear coat. Refer to your paint manufacturer's prep guidelines for best adhesion.
