Does this bumper need painting before installation?

Finish condition is not specified — inspect upon arrival and assess whether primer or paint prep is needed before bolt-down. If you're planning to paint, handle that before mounting to the truck.

Will my factory backup sensors fit through the pre-cut hole?

The sensor hole is sized for OEM sensor fitment. Test fit your sensor before final tightening to confirm alignment with your specific truck's sensor bracket.

What hardware do I need to bolt this on?

Mounting hardware is not included in this assembly — you'll need fasteners that match your truck's factory mounting points. Refer to your vehicle's service manual or dealer parts diagram for the correct bolt spec and torque values.
