      • Not suited for 2019+ models with lower chrome protectors
        While they do not hinder the installation of the side sills, they may appear out of place visually especially since the front chrome protectors need to be removed for installation of the Front Air Dam.
        Removal of the chrome protectors on the doors will expose the alignment holes.
        Alternatively, contact us regarding the black side protectors (without chrome inserts) found on the doors can be purchased separately.
