Here's my new 2020 Denali 2500HD. I bought it from the dealer already built and to be honest, I don't know all of the details. I'll find out and give an update. My understanding is that it has a 2" leveling kit installed. It drives great and no real noticeable difference from a stock truck. Running 37"X12.5" Nitro Grapplers on Fuel wheels. There has been a little trimming to make fit the 37's and they do rub slightly on occassion. Also replaced the factory running boards with Amp Research Power Step XL's. I'll return with some information soon.
