Do these mount to the factory roof rails directly?

Yes—they're designed for factory mounting points. No drilling or custom brackets required. Your existing roof rail system handles the install.

Will I need to add fasteners or hardware?

Test-fit your specific roof rail setup first. Some installations may require additional fasteners depending on your rail design—have basic hardware on hand before you start.

Can I use these with a cargo carrier or roof box?

These bars are built to accept standard roof-mount accessories. Make sure your carrier or box is rated for your vehicle's roof weight capacity before loading.
