Will these mount directly to my factory roof rails?

Yes, these crossbars are engineered for factory roof rail attachment at the existing mounting points. No drilling or rail modification needed.

Do I need to apply any finish or sealant before installing?

Aluminum is naturally corrosion-resistant, but check connection points where bars meet your rails—a light application of silicone or grease at contact surfaces prevents moisture trapping and noise.

What's the weight difference compared to steel bars?

Aluminum crossbars are significantly lighter than steel equivalents, which reduces unsprung weight and improves fuel economy without sacrificing load capacity.
