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

These crossbars mount at your factory roof rail attachment points. They work standalone for basic cargo tie-down, or they serve as the foundation for aftermarket roof baskets, cargo boxes, and bike racks — which mount on top of these bars.

Will I need additional hardware or fasteners to install these?

Mounting hardware for factory attachment points is not specified in the product data — verify that your existing roof rail hardware is present and in serviceable condition before install.

Can I paint or refinish these bars if they get scratched?

The bars arrive in black finish. Touch-up or full refinish is possible with standard automotive paint, but test fit and confirm mounting clearance before any finishing work.
