Are there any companies that make a stock spring height that is built like the RE for SOA?
Or is the 1.5 RE the best spring to use? (off the shelf).
If you're going to stick with stock springs get HD or all rear leafs. Front leafs are a bit too soft. I don't believe anyone makes reverse arched leafs unless you get them custom.
If I was going to do my suspension again, I'd consider a 4.5" Deaver SUA leafs and some 5/8" shackles. Alcan Springs and National Springs can make custom leafs. When I checked with them years ago, they could make 1"-6" at no cost difference. These aren't cheap by any means though you get what you pay for.
I currently run stock 5 leaf rear packs SOA up front and 3.5" SUA Trail Master leafs in the back. The Jeep sits level with a .5" height difference at either end. If I take the top off, it's about 1" higher at the rear. It's pretty soft which is what I really like about it. Not to mention, cheap since I was already lifted when I did the change over.
