Do I need special fasteners to install this, or does it come with hardware?

Installation hardware is not included with this set. You'll need to source fasteners rated for your vehicle's roof attachment points — check your owner's manual or consult a dealer for the correct bolt grade and torque spec.

Can I put these on right out of the box, or does the black finish need prep?

The bars ship with a black powder-coat finish ready to install. No sanding, priming, or painting required before mounting.

What weight can these bars actually handle?

Load capacity depends on your vehicle's roof load limit, which is stated in your owner's manual or on the driver's door jamb placard. Mount accessories securely and never exceed that ceiling — the bars themselves are engineered to work within your vehicle's design limits.
