Do these rails mount at factory attachment points?

Yes — these use the factory mounting points on your truck bed, so no drilling or modification is needed. Installation is straightforward with basic hand tools.

Will I need fasteners or hardware beyond what comes in the box?

The rails come as assembled pieces. Confirm mounting hardware compatibility with your vehicle's service manual before install to ensure you have the right fasteners on hand.

Can I repaint these if I want a different color?

The black powder coat finish is ready to use as-is. If you want a custom color, light surface prep with 150-grit sandpaper followed by your choice of automotive paint will work, but test on a small area first.
