Do these bolt to factory points or require drilling?

These use factory mounting points — no drilling into the frame. You'll bolt them into existing holes on the rocker panel.

What hardware comes with them?

The assembly ships with everything needed to mount at the factory attachment points. Confirm your hardware against your vehicle's OEM manual before final install.

Can I use these as a step to get into the bed?

Yes — the 3-inch diameter tube is designed to handle weight. Avoid standing on the mounting bracket itself; distribute weight across the tube.
