I would like to swap YJ springs onto my CJ and have a few questions on the YJ springs. Does a 3" lift YJ spring give 3" of lift on a CJ? I was checking the Warn catalog and the YJ springs have a greater arc than the CJ for the same 3 inches of lift. I have a 3" pro comp lift on it now and would like to stay with the same height, what height Wrangler springs will work? Thanks for any help.
