I have a set of black diamond 4" springs in the front of my 87 ramcharger and i need to soften them up. the leaf pack is 5 leafs with 3 clamped and 2 seperate springs held on by the center locating bolt. I was going to pull a leaf or 2 but i'm time limited so i only want to do this once before this weekend. What leaf do i want to pull?
