Im about to buy a set of rear lowering springs for my 01 denali. Is it mandatory to get shock extenders for a 2 or 3 in rear drop? Im worried about the air ride. I pull a trailer from time to time and dont really want to loose it. Any help will greatly appreciated. Also who has the best deal shipped to your door? I need front keys, rear springs, and maybe shock extenders. Looing to lower it 2 in the front and 2 or 3 in the rear. LMK what is best.
