Will this work with my current hardware and fasteners?

Standard stainless steel bolts and washers from any hardware store will work fine. Exact fastener size and count depend on your vehicle — check the bracket holes against what you have on hand before ordering.

Does this come with mounting bolts?

Bracket only. You'll need your own fasteners. Most installs use basic metric bolts available at any hardware store or your local dealer parts counter.

Do I need to prep or paint this before install?

Black finish ships ready to bolt on. If you want a custom color or protective coating, light sanding and spray paint work fine — just mask off the mounting holes before you start.
