Does this need hardware to mount, or is everything included?

The bracket itself is included. You'll need to verify what fasteners work with your vehicle's front fascia attachment points — most use factory hardware already in place. Test-fit before final installation.

Does the black finish need any prep or paint before I install it?

The bracket comes with a finished black coating ready to mount. No painting or sanding required out of the box.

Can I install this without removing the bumper or fascia?

Yes — it attaches at factory mounting points on the front end, so you can bolt it on without full bumper removal. Basic hand tools are all you need.
