As we mentioned the entire bumper is bolt-on. Carli did this for a few reasons. It made the piece easier to get on and off, easy to install, and requires no cutting or welding for the customer. All we needed to do was unbolt and remove the lower valance portion of the stock bumper and bolt-on the new one. Here you can see the lower mounting points of the bumper. Carli chose to use factory mount locations for easy install.
