Yo I have a Denali and trying to do something like this. I have the 4” ready lift. But I have 22 that came on the truck did you have to do any cutting ?
One of the reason this set up worked is because the wheel was a 18x8 so it clears away from the upper control arm. You’re limited on sizes in a 22”. To get the height without going wide is the challenge.
This lift kit comes with a 3 inch block. The At4 comes factory with a 2 inch block. So that would be 1 inch lift in the rear and 2 inch lift in the front which would level the truck out.
