I'm about ready to order a 4" lift for my '72 blazer. I would like to go with TC springs all the way around. From what I have read on here, it sounds like I should go with 4" springs in the front and 6" springs in the back to fix the saggy rear problem. I was also considering getting 4" springs all the way around and then getting a 1" zero rate for the back. Anyone done either of these options? How did it work out for you? Pics? I would like to end up with a level to slight stink bug stance.
