Anyone running 305/45/22's on OEM 22's with a level kit? If so I would love details as this is the setup I am looking at for my 2017 All Terrain. Truck has a 2" Rough Country lower spacer and GM accessory 22's.
Not an expert here, but I think the problem with the lift is the autoride, not autotrac. Autoride involves electronically controlled shocks and struts which are a problem that would have to be dealt with on a lift. You are correct that your Denali would not have autotrac.
