Will my backup sensors work with the sensor holes pre-drilled?

Yes. The holes are factory-spec; wire your sensors through and they'll function normally. No additional drilling or modification needed on your end.

What hardware do I need to mount this?

You'll need bolts compatible with your truck's factory rear bumper attachment points. Grab your service manual or check with a local shop for the exact fastener specs—they vary by model year.

Does this come bare steel or finished?

It ships as bare steel. Plan for paint or protective coating before installation if you want rust resistance and color match to your truck.
