Do these mount without drilling into my truck bed?

Yes. They bolt directly to factory mounting points on the bed frame—no drilling, no modifications needed.

Will I need additional fasteners or hardware to install these?

The guard assembly ships as pictured. Confirm your truck's existing bed fastener setup before install; you may need standard bolts or clips depending on your bed configuration.

Can I paint or modify the finish after purchase?

The black finish is ready to install as-is. If you want a different color, sand lightly and apply automotive paint or powder coat—prep the surface like you would any plastic component.
