Do these bars need any prep or paint before I install them?

They arrive ready to bolt on as-is. If you want to paint or finish them differently, sand first and use an aluminum-compatible primer and topcoat.

What hardware do I need to mount these to my roof?

These bolt to your factory roofline mounting points — verify what fastener size and type your vehicle uses in the owner's manual before ordering hardware separately if not included with your specific set.

Can I use these bars with any roof box or basket?

These crossbars work with most standard roof accessories designed for crossbar mounting. Always confirm your cargo system's clamp width and weight rating match these bars before purchase.
