Will this fit if I have aftermarket bumper covers or lower valance extensions?

This bar mounts at factory points, so it works with OEM bumper geometry. If you're running aftermarket bumper covers or extended valances, you'll need to test-fit to confirm clearance — some aftermarket pieces sit lower or project further than stock.

Do I need to remove the factory bumper to install this?

Not necessarily. You can access the mounting points with the bumper on, though removal makes the job cleaner. Either way, you're bolting to existing holes — no drilling or permanent modification of the bumper itself.

Does this come with bolts and fasteners?

The bar ships as the component itself. Fasteners are not confirmed in this listing — verify your hardware against your vehicle's service manual before final assembly, or reach out to confirm what's needed for your specific application.
