There was some "guessing" at the beginning of this thread. Of course this thread started when the new body style had just arrived so understandable. I was thinking my journey may further help someone. I did this mod 9 months ago. The jacked up rear of my AT4 bothered me. And the tailgate height was awfully high when down. The stock AT4 rear spacers are 2" thick cast iron. Removed the 2" spacers completely. Made it a bit lower in the rear than the front. Looked all wrong. My 2016 Denali had the same tail happy rake when new as the AT4. Denali had 1.1" cast iron spacers that I removed and were sitting on a shelf.(The Denali needed additional modifications but that's a story for another thread). Put in the Denali spacers(exact fit). Still has a rake but now it looks just right to me. And the tailgate height dropped about 2" at the rear when down. Original U-Bolts worked fine. I did pull the lower shock bolt and tested for shock travel. No issues there. Headlight aim wasn't changed enough to be a concern but I did lower their beam a ½ inch as measured on my wall. I have a lift but using it wasn't necessary. Made the swap as it sat on the garage floor with the help of a floor jack. Simple as it gets. Ride is slightly smoother. And I like how the truck handles rough roads now. The rear stays planted a little better. Dropping the rear ⅞" transfers enough weight off the front that the front height increased a solid ⅛". That means the truck has better weight balance front to back. Nine months later, no issues and very happy. Towed an old Corvette. Hauled a lot of 300/600 lb loads and a pair of speakers weighing 1150 pounds in the bed. Surprised at the small amount of rear sag with that much weight. Again, no issues at all. I know most are happy with their Tail Bosses and AT4's as is and I get it. But this mod was well worth it for me.

Yes sir, it is. Reminds me if the Accelerate Yellow on the C8 except for the metallic part.

Does this count? Local dealer has a few.
