Do these mount directly to the roof or do I need a separate rack system?

These crossbars mount at the factory roof points on your Soul — no separate rail system needed. They're the foundation you attach cargo boxes or baskets to.

What fasteners do I need to install these?

Hardware for roof attachment is not included. You'll need to source bolts and clips that match your vehicle's factory mounting holes — your dealer parts department or service manual will have the spec.

Do these need paint or any prep before installation?

Aluminum naturally resists rust, so no paint prep is necessary. Install straight out of the box and seal any fastener holes after mounting to keep water out.
