Will these mount directly to my roof or do I need a roof rail system?

These are designed to use your vehicle's factory mounting points — no additional rail system required. Verify your Soul has the roof attachment points before ordering.

Do I need to finish or paint these before installing?

Aluminum naturally resists corrosion, so no prep or paint is required. Install them as-is straight out of the box.

What hardware comes with these crossbars?

The listing confirms the crossbars only — mounting hardware is not included. You'll need to source fasteners compatible with your Soul's roof attachment points; refer to your owner's manual for specifications.
