I am getting ready to build a new trail rig. I bought a 91 wrangler body and frame. I was planning on front waggys all around but measured the center to eye on a rear HD cj7 and it is the same as the waggy short side. The only advantage to the waggys I see is the arch to obtain the lift needed for the 38.5 14.5 SXs I would like to run. If I use cj springs I might need a body lift. So is there much difference in spring life or flex limits? I know they both flex well but is one better than the other? Has anyone ran them for a while and know?
