Do I need hardware to install these?

Installation hardware is not included with the crossbars. You'll mount them at your factory roof rails using existing attachment points — bring the correct fasteners or check your owner's manual for what works with your specific roof rail setup.

Can I use these right out of the box?

The crossbars come finished and ready to mount. No paint or prep work needed before installation.

What weight can these handle?

Load capacity depends on how they're secured to your roof rails and the condition of those attachment points. Refer to your vehicle's service manual for roof load specifications before carrying gear.
