Will I need fasteners to bolt these on?

Fasteners are not included with this set. You'll use the factory bolt holes at the rocker attachment points — have your fasteners ready before starting installation.

What prep work is needed before paint?

Light surface sanding followed by a standard automotive primer application will ready these for your chosen topcoat. Follow your paint manufacturer's surface prep guidelines for best adhesion.

Do these fit without any modification to the truck?

These mount directly to factory rocker points — no drilling, cutting, or welding. Bolt them straight on using the existing attachment locations on your vehicle.
