Does this come with bolts and mounting hardware?

The listing confirms the bar assembly only. Source fasteners from your local hardware supplier or verify fitment with factory bolt specs before ordering.

Will I need to prep or paint this before install?

Comes with a powder-coat finish ready to bolt on. If you want to match a custom color or add protective coating, sand lightly and paint after install once you've test-fit the pieces.

What tools do I need to install this?

Basic hand tools and a socket set. Refer to your vehicle's service manual for torque specs on factory mounting points. Install time is typically a couple of hours.
