Want to lower the rear of 99 4x4 Tahoe 3"-4" will 2wd springs lower the truck? are there inexpensive rear leaf spring options? or is droped hanger/shackles the way to go? I guess removing overloads and adding overload air bags for towing may be a good option. I have plenty of suspension and fab skills, knowledge, and experiance just not with these trucks. I read most of but not all of 4x4lowering and searched already.
