I went for the (mostly) blackout option. I appreciate the “black chrome” that GMC threw on the AT4 and AT4x grille and side engine badge, So I’m going to leave that, but with the new black wheels and the Thunderstorm grey color, I felt the bright chrome emblems and badging was just Too much. So I’ve replaced all GMC/Sierra/AT4 badging with black options (with red left on the 4, but no chrome). Not for everyone, but I think it’s a pretty good, more subdued look.
Front and rear satin black surround with gloss black inner “GMC” emblems were purchased on eBay.
The “Sierra” and “AT4” gloss black emblems for the tailgate and front doors were purchased through GM. Easy enough install for all, but I also went for @Wakinvol’s option 2 on the front grille GMC emblems. I knew I wouldn’t want to go back to red and chrome emblems, so I took the old screwjy to the inner red parts of the GMC letters to remove them from the main chrome parts. Once they were removed, it is very easy to remove the individual GMC letters from the front grille using a small flathead.
Still debating on the black AT4 grille emblem
