Do these bolt directly to factory attachment points?

Yes. They mount at OEM rocker mounting locations — no drilling, welding, or custom fabrication required. Standard hand tools and a jack are all you need for install.

Does this come ready to install or does it need prep?

The assembly ships ready to bolt on. Before mounting, clean the contact points on your truck's rocker panel to ensure a solid fit. Paint or protective coating is optional depending on your finish preference.

What if the bars don't sit flush after I bolt them down?

Test-fit first with the fasteners hand-tight. Adjust alignment before fully tightening. If gaps remain after full tightening, the rocker panel may need minor shimming — use stainless shims to avoid corrosion.
