Will this fit over my factory bumper or does it replace it completely?

This is a cover that installs over your existing bumper frame using factory mounting points. You keep the original structure in place—this gives you the chrome look without a full bumper swap.

Do I need to remove the lower valance or bumper sensors to install this?

Mounting method details aren't specified—test-fit the cover against your current setup before installation to confirm clearance with any sensors or trim pieces on your truck.

Is the chrome finish painted or plated?

Chrome finish is applied and ready to bolt on. No prep work or painting required before installation.
