Do these mount to the factory rocker panel or do I need additional brackets?

These use factory mounting points—no extra brackets needed. Installation is bolt-on at the existing attachment locations on your cab.

Will the chrome finish hold up to road salt and washing?

Chrome is corrosion-resistant, but regular rinsing after salt exposure keeps it looking newer longer. Dry after washing to prevent water spotting.

What hardware is included to bolt these on?

The bars ship as assemblies ready to mount at factory points. Verify bolt sizes match your truck's existing rocker fasteners before installation—your service manual lists the torque spec.
