Do these rails require drilling into my bed?

No. These mount at factory attachment points, so no holes or modifications to the bed itself. Installation is bolt-on only.

Will these come with all the bolts and hardware I need?

Hardware is not included with these rails. You'll need to source bolts and fasteners that match your truck's factory mounting specification—check your vehicle service manual or contact the dealer for the correct bolt size and torque specs.

Does the chrome finish need any prep or maintenance after install?

The rails arrive ready to mount with a polished chrome finish. After installation, wash them with soap and water to remove dust and protect the finish. Avoid abrasive cleaners that can scratch the plating.
