Google doesn't search very well here!

Anyways, looking to get an idea of where to start. I have stock YJ springs SOA, they are slightly inverted right now. I need 2-3" lift out of them.

I have a donor set of stock YJ leafs here too. Which leafs can I add to get close? If someones already done it, it'll save me from bolting it all together only to undo it all and try another combo!

Right now I'm planning on adding the main leaf from my donor pack with the eyes cut off as my first try. I need a little extra stiffness from the pack becuase I'm adding some more weight out back too.

Thanks!

Why would you want 2-3" more lift in the arch? Stock length springs with that much arch would have a shorter eye to eye length, giving you less down travel.

Flat springs on SOA are the best for articulation. I would look at 1.5" shackles. That would allow for more movement. 2" body lift would allow for taller tires.

I added one more full length leaf (junkyard) to each of my springpacks and have good results on my 93YJ. The rear springs are flat, but I easily clear 37" MTR's.

If for just handling more weight I think an added leaf would be the best. It's easy and easily changed if you don't like it.

Well, my setup is a bit different than a YJ's, I've got a TJ with custom everything. What I want to do is move my rear shackle up higher so I don't slam it so much on rocks and logs etc... I'd rather lose a little travel than keep smacking into stuff so much!

I want to keep my axle in the same location, so I need a spring with a little more arch to it to get the rear eye higher.

It sounds like you're on the right track. The extra leaf project I did probably netted about 1" lift, but with the springover it will settle down about that much.

Between junkyards and guys selling springs, you could go either route pretty resonable. If you have a few green stamps Alcan Spring could make you a custom set that you would never be sorry for and make your project shine.

Your saying you added the extra full leaf and only got 1" lift? Thats what I'm trying to find out. If I need to, I can add the extra main leaf with eyes cut off, and the next leaf down as well. Maybe remove the shortest leaf?

Trying to get a starting point...

yeah they are. i killed all four of my stock springs pretty fast when i did my initial SOA on my YJ. Now i'm running 1.5" springs with an extra leaf in the rear and Rancho 44050's in the front. works great, a little taller than i want but nothing to complain about yet

Are you guys running an anit-wrap bar or just relying on the springs? I'm running an anti-wrap bar and I don't feel the stock springs are soft at all. If you guys are running bars, maybe I did something wrong??!!
