Does this require drilling or cutting into my stock bumper?

No. The lip mounts at factory anchor points — no drilling, cutting, or permanent modification needed to your bumper or vehicle.

Will this work if I've already installed aftermarket fog lights?

Test-fit first. Aftermarket fog light housings vary in depth and shape — some may sit closer to the bumper than OEM units. Measure your setup before final installation.

Do I need to paint this before installing it?

The lip ships unfinished. Paint and primer before installation for best results and to match your truck's color.
