Do these mount to existing holes or will I need to drill?

These are designed for factory mounting points — no drilling required. You'll use existing frame attachment locations on the rocker and cab area.

What fasteners do I need to complete the install?

Mounting hardware is not included with the bars. You'll need to source bolts, washers, and lock nuts that match your vehicle's factory attachment points. Check your owner's manual or service documentation for the correct fastener specs.

Can I paint these before or after installation?

Either way works. If you paint after installation, tape off the mounting zone to keep fastener holes clean. If painting before, handle the bars carefully to avoid surface damage during mounting.
