Will this bumper work with the OEM rear bumper beam?

Yes. This cover mounts directly to factory mounting points without requiring beam modification or relocation. Install is bolt-on to existing hardware.

Do I need to paint this before installation?

Not required, but recommended. The bumper Requires Surface Prep, meaning it has a gray primer base. Most builders sand and paint after install for final finish, though some install unpainted and finish afterward depending on workflow preference.

Will fog light holes or sensor cutouts need to be drilled?

This bumper is designed for stock applications without factory fog lights or integrated sensors. If your build includes aftermarket fog lights, you'll need to drill your own holes in the cover after test-fit.
