Re: re arching springs??
I can't really give you the answer(s) to your questions...at least how a re-arched spring will work in a lift, or if they'll last longer before sagging. What I can do is tell you a re-arched spring doesn't hold is tenison for any great length of time. I've done it a couple of times in the past when I wanted to buy myself some time before I replaced them with new ones. I always used them on a stock CJ, never a lifted one. So, from my point of view,,I suggest you just get new springs if your planning on keeping your jeep for a perod of time. Also, if you do elect to re-arch your existing springs do it your self,,if your going to pay someone, you may as well save the money and put it toward the new springs.
