I am very close to purchasing a used 2021 Tahoe LS. If I get it I would like to level it and maybe slight lift in advance of a set of 33’s. I would like to keep the current ride or just slightly firmer. Question: rough country says they have a kit for this but I have also come across an AT4 pull-off suspension from a 2022 1500 PU that I can get cheap. Anyone done either of these options or have experience with this?
