Will this work with an aftermarket rear bumper cover?

This bar is engineered for the OEM rear bumper. If you're running an aftermarket cover, verify the mounting points align before installation — some aftermarket bumpers use different attachment locations.

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

You'll need to access the mounting points behind the bumper. Removing the bumper cover gives you the clearest work space, but mounting may be possible without full removal depending on your comfort level — test-fit first to confirm.

Does this come with bolts and hardware?

The reinforcement bar ships as the structural component. You'll use your existing OEM hardware — gather what came off your vehicle during removal and reuse it for installation.
