Do I need fasteners to install this, or are they included?

Hardware is not included with this bracket. You'll need fasteners compatible with your vehicle's factory mounting points—check your owner's manual or service manual for the correct bolt size and torque spec.

Will this require any drilling into the bumper or frame?

No drilling needed. This bracket mounts at factory anchor points, so installation is completely reversible if you ever want to remove it.

Does this bracket come primed or painted?

The bracket ships in raw hard panel form. You can paint it to match your bumper before or after installation, or leave it as-is depending on your preference.
