I have a 2011 suburban LTZ 1500 4x4. I wanted to put a 285 or a 295 on it.I was looking at lifts,the 2.25 ready lift or the 4" sst lift. I was told by a rep that only a 285 will fit on the stock rim(20 inch, which i want to keep on it) with the 2.25 lift.If anyone has lifted a 2011 suburban,with the stock rim,could you tell me what direction i should go and what to use?
