Do I need to remove the OEM bumper to install this?

Yes. You'll need to unbolt the factory cover first. The Raven cover bolts directly to the same mounting points, so no additional brackets or modifications are needed.

Will the fog light cutouts line up with my factory fog lights?

The Raven design features standard fog light openings. Before installation, verify that the cutout positioning matches your vehicle's factory fog light housings. If your bumper has been previously damaged or replaced, compare the hole locations carefully.

What should I use to prep this before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust. Follow your chosen paint system's surface preparation guidelines for best results.
