I have a 2017 GMC Sierra elevation. I bought it used and it came it a 1” leveling kit in the front. (Idk why you’d go with 1” but the previous guy must have thought it was a good idea lol) my tires were rubbing pretty hard one the upper control arm, and I wanted to level the truck farther. What I did was install 2” drop shackles in the rear and 2” wheel spacers. The truck now only has a 1/4” of wrack and the tires no longer rub. In the future I’ll upgrade the spacers for some nice offset wheels but at the time this is what I could afford.
