Do these mount at the factory rocker points?

Yes — these bolt at factory attachment locations with no drilling required. You'll need the appropriate fasteners for your vehicle; check your service manual for torque specs.

Does the silver finish need prep or can I bolt them on as-is?

The powder-coat is ready to install. If you want to touch up scratches or repaint, light scuff and prime before paint.

What hardware comes in the box?

Bars only — you'll supply the bolts and fasteners. Quad cab trucks vary in attachment hardware, so verify your bolt size and length with your dealer or service manual before ordering.
