For some time now, I have heard tell of a cheap way to lift just about any late modle jeep, are at least those that run on a stright axle and leaf springs.
The process is to change the location of the axle, and springs. From what I can guess, you set the springs on top of the axle, and all or just about all hardware will go back in place.
To me it sounds to easy, what about the A arm and linkage for shifters, brake lines and shocks, as well as the angle of the drive lines?
What are Pros and Cons to a change like this?
How will the jeep handle afterwards? (Body Roll) had exp with Frord Bronco!!! I turned it in to a fast back:punk: With the help of a UPS truck and a skill saw.

Any thoughts will be useful:doh:

this is called soa (spring over axle), and i hate when people think its cheap. it isn't at all, it costs more to do soa the right way than just buying a lift kit. the whole misconception is from people thinking they can save money by not buying new springs. it is not a bolt on lift kit, it requires welding, and customizing the suspension and geometry angles, as well as pinion angle. brake lines, steering linkages, spring perches are just a couple things that have to be changed and/or fabricated.

and with the age of yj's now most going on the original springs, its not a good idea to do soa on old leaf springs anyway.

Its called an Spring Oover or SOA. The easy part is moving the springs over the axles.. welding of course new spring hangers. As you mention you have to address the steering, drive shafts. Figure about 1k to do it right.

forgot about this part, it is all pros basically as long as you want that much lift. you're gonna get about 6" as long as you do something with your old leafs, beef them up or replace them. if done correctly it will ride as good or better than stock, sua (spring under lift) kits don't offer this. you will need 33" tires minimum, and then you get to start looking into upgrading axles.

if you wanna go a little cheaper and easier a regular 2.5" or 4" sua lift is the way to go.

I call broken man law!

Rule 127 clearly states "one man may not make a statement and then call a "that's what she said" on his own statement"

Punishment-give the hobo under the freeway five bucks and MAKE SURE he spends it on beer!

:p

Welcome to the forums and keep us posted especially if you do an SOA

Can I also add that when it's done wrong, a SOA lift can be dangerous. Doing it wrong is usually the same as doing it cheaply, unfortunately. You can end up with a super tippy jeep that throws out most of its driveline when you hit a bump. You can wrap the old springs into pretzels when you stomp on the gas.

Do it right, and it's fine.

Other options include a simple shackle lift, body lift and/or clearancing (cutting) the body. Although lifting the suspension can be a good thing, it can also be a bad thing. Being too tall can make things tippy, and the lift that matters most is the lift you get from bigger tires. Bigger tires lift the axles off the ground, while suspension only lifts everything above the axles. Body lifts are even worse, since they don't allow for any more ground clearance from the belly, or under the axles. They do allow for some mods though.

Xtreme 4x4 put Genright corner panels on a TJ (also have for YJ) that allow 35-inch tires on a stock lift. This keeps the center of gravity low, requires no other changes (SYE, draveshafts, pinion angle, etc.), and it adds some serious body-panel protection. That being said, 35's are guaranteed to break the rear D-35. The price for the panels was $1570 though, so not very cheap.

If you are looking for cheap, easy and 3", I would consider a new set of extended shackles and maybe a body lift. The combo will allow you to clear bigger tires, without the expense of changing other parts.

Ditto to the guys who say a SOA is not cheap or easy and can cause a lot of problems if not done right.

Good luck!
