Do I need to remove the bumper cover to install this bracket?

Yes. The bracket bolts to the frame behind the cover, so you'll need to unbolt and set aside the cover first. Once the bracket is secured at the factory mounting points, reinstall the cover and bolt it back down.

Will this bracket work if my bumper cover is cracked?

A new bracket won't fix a cracked cover, but it will restore proper support to a functional one. If your cover is damaged, address that separately before or during installation.

What hardware do I need to bolt this down?

Mounting hardware is not included. Use OEM bolts and fasteners specified in your vehicle's service manual, or reference your original bracket setup to match size and torque specs.
