It is time to do some spring work on the rear end. I have a set of springs from a little Cherokee that I think will work pretty well, but, it will require the relocation of at least the rear attachment. The process would be simplified significantly if I could move the springs under the frame, instead of having to fab a mount out in space outboard to the frame. I understand the fabrication obstacles before me, and I can pull it off either way, I just need to know what negitives this option might represent in terms of handling. It seems like articulation would be better, but on road sway would be worse. What have you done.

Thanks.

You are right; with inboarded springs, the sway will be worse and the articulation will be better. You might need to use a sway bar in the back, but it will depend on the stiffness of the springs, etc.

I would think that the frame will need to be reinforced (boxed) in the area where you attach the rear hanger, since it is just open c-channel in that area.

I'd say put those XJ springs under the frame, and let us know how it works out. After all, someone has to go first

I have thought about doing exactly what you are proposing, either with XJ or YJ springs, but that project is pretty far down my list right now.

I'm going to be doing the same thing with RE YJ 1.5" spring over springs. I think the payoff with much added flex is a good one. My question is though what do you plan on using for spring hangers? You going to fab up some or is there a source from another Jeep like a CJ or YJ? Maybe someone makes spring hangers? I dunno??

Here is what I did with my rear suspension.

Okay, looks like I'll give it a shot. I'd like to avoid needing an anti-sway bar in the rear, but, what the heck.

I'll probably make all the mounting points. I found some tubing that has the perfect inside diameter for a common poly shackle bushing. I use channel the same width as the spring to be used, then cut a radius out of the flanges so the tubing can be welded on. When and if I get to this, I'll post the results. I'm planning on using the stuck rear 44, so the increase of mechanical advantage against the springs (increasing body roll) should be less than if I were using a full width Wagoneer axle....I hope.

Thanks for the information Jeepster Jim.

If you are using stock width axles I say go for it. I have a stock width rear axle that is setup with wrangler springs directly under the frame SOA. I like the extra flex, and the handling is not any worse than before. My only beef with my setup is that there are very few choices on where to mount up shocks. My shock setup just plain sucks right now, becasuse I cannot tilt them inward to the center while using a ladder type traction bar, thus I run a short shock. I am going to move to a scout width rear to hopefully free up some room for a better shock setup. The rear section of my frame is fully boxed, I have not had any frame cracking issues.
