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

These bolt at factory mounting points—no drilling needed. Test-fit before final tightening to ensure alignment with your specific bed.

What hardware do I need to install these?

Mounting hardware is not included with this set. You'll need bolts, washers, and lock nuts sized for your factory mount holes—verify your truck's fastener spec before ordering hardware separately.

Can I repaint these rails if I want a different color?

The black powder-coat finish can be sanded and repainted, but test on a hidden area first. Rough the surface lightly, prime bare steel, and apply automotive paint per the manufacturer's instructions.
