Do these mount directly to the factory roof rails?

Yes. These crossbars are designed to seat on your vehicle's factory roof rails — no drilling or welding required. Verify fitment with your rail system before installation.

Will I need additional hardware to secure the crossbars?

The crossbars themselves come as shown. Check your vehicle's roof rail documentation or contact your dealer to confirm what fasteners or clamps you'll need to lock them in place — those may be sold separately.

Can I paint or seal these if I want a custom finish?

Aluminum can be painted, but clean and test-fit everything first before committing to any finish work. The factory coating is already protecting the metal — only repaint if you're matching a custom color or if the coating gets damaged.
