Will these mount directly to my roof rails without adapters?

Yes — these are designed for factory mounting points. No adapters needed. Hand-tighten all connection points before loading and confirm everything is secure.

Do I need to prep or paint these before installation?

No prep required. They ship ready to install in black finish. If you want to customize the color, clean them first with mild soap and water, then sand lightly before painting.

What hardware comes with the set?

The set includes the two crossbars. Check your vehicle's roof rail system for existing fastener points — most factory rails have pre-drilled holes. If you need additional fasteners, measure your mounting points and source stainless steel bolts locally.
