View attachment 260609 View attachment 260610 on the 15 up yukons there is a small textured black lower trim piece, lines up nicely with step boards and front valance.
i prefer the look of it, but the burbs do not have it. i noticed when following a lifted yukon, gives a slightly higher appearance, and a little protection to the rear lower edge.
To me it looks like the Suburban's is part of the bumper cover, but color matched.
