My '93 YJ (2.5 5 spd) was lifted by the previous owner. I was told 2.5". He didn't like the ride quality so he had 1 leaf removed from each spring. Each spring pack now has 3 leafs. I have added 3/4" boomerang shackles. When I measure, I actually have 4" of lift. Here's my problem. I added a Quadratec winch which is pretty heavy (over 100 lbs.). My front springs are not reacting too well to the added weight. I can tell they are wanting to give up and start sagging. So, will installing add-a-leafs in the front help, or do I need to replace the springs with new 2.5" springs?
