Do these mount at factory rocker points or do I need to drill?

These are designed to use factory mounting points — no drilling required. Test-fit before final fastening to confirm alignment with your specific setup.

Can I paint this or does it need primer first?

The black finish can be painted over directly. Light scuff with sandpaper and wipe clean before applying your paint or primer to ensure adhesion.

What fasteners do I need to install these?

Mounting hardware is not included with the bars themselves. You'll need to source bolts and fasteners that match your vehicle's factory rocker attachment points — check your service manual or contact a dealer for the correct spec.
