Does this require drilling into the bumper cover?

This reinforcement bar mounts at factory cradle points on the frame—no bumper drilling. You're bolting directly to the structural assembly underneath.

Will this work with the factory bumper sensor?

The bar installs behind the bumper cover. If your bumper has a center sensor, verify sensor placement before final assembly to avoid any contact with the reinforcement.

Do I need to remove the entire front bumper to install this?

You'll need to access the frame cradle from underneath or remove the bumper cover for clearance—exact approach depends on your access. Factory attachment points keep the install straightforward once you're in position.
