This is our dual 40" light bar kit for 2020+ Sierra 2500/3500 HD trucks, AT4 included. Both bars sit behind the grille and shine through it, so you get a lot more light while the truck keeps its factory look. They use a spot and flood pattern, which gives you distance down the road plus width to the sides.
Here's the 40" SLIM next to the 40" PRO at night:
