Will this bumper work with my factory fog lights?

Yes. The fog light cutout is pre-drilled to approximately 3.5" diameter, which accommodates standard factory fog light housings. You won't need to cut or modify the opening.

Do I need to modify my bumper sensor cutouts?

The raw bumper does not come pre-cut for lower bumper sensors. If your vehicle has factory parking sensors in the bumper, you'll need to carefully cut those openings to match your original sensor locations.

Does the B-2 style work with my stock lower valance?

The B-2 profile is designed to sit cleanly above a lower valance or diffuser. Verify your specific valance clearance before final installation, as aftermarket combinations vary.
