Will this fit my truck if it has aftermarket fender flares?

No. This bumper cover is not compatible with fender flare kits. If your truck has flares installed or you're planning to add them, you'll need to verify clearance separately or consider a different bumper design that accommodates that setup.

Does this bumper have sensor or fog light cutouts pre-drilled?

No pre-drilled holes are included. If your truck originally had rear sensors or fog lights, you'll need to reference your vehicle's OEM bumper hole locations and carefully drill matching openings in this cover before installation.

What surface prep do I need before painting?

Sand the surface with fine-grit sandpaper until smooth, then wipe clean of all dust. Apply your chosen primer and paint system according to the product manufacturer's instructions. Proper surface prep ensures paint adhesion and a professional finish.
