"Axle Under Lift"?

While talking to my neighbor recently (He owns a '97 TJ), he said something to me about getting something called an axle under lift. He said it had something to do with the axle going under the leaf spring, and its about a 5" inch lift. I have never heard of it and he didnt know a whole lot... so can anyone tell me more about it?

Thanks

Sounds to me like a SOA or Spring Over Axle lift. You get a lot of height from it for a reasonable price, it's also easier to replace factory springs when you start to sag than it is to deal with a sagging suspension lift.

its called a soa (spring over axel conversion) and you pretty much get the height of the axel tube as that much more lift with out sacrificing how it drives

it's not so simple. It's a SOA(spring over axle) as mentioned above. It should net you bout 5.5". When going that high along with the SOA setup, you will have to consider the cost of an SYE/CV combo for driveline angles, brake lines, possibly steering issues, axle wrap, and tires and their affect on power and you stock axles.

going SOA is no walk in the park. it generally requires new axels, some steering components, like a high steer system, dont think you need it with stock springs though. extended brake lines, drive line angles. wether or not its your daily driver makes a difference too

You can definitally do it. Its just very costly and hard to get right if you DD. I am doing it very soon and its going to be my DD with 2" spring too. Its going to have like 7-8" of lift along with 35's or 37's. And Vortec motor... blah blah lots of money. Anyway you have to deal with steering, rear axle (the Dana 30 front will hold up to 37s, that I have seen), CV shafts front and rear, SYE, shocks, mounts brake lines and some other misc stuff . Hope this helps out.

It is not as hard as every one is making it out to be. My buddy Charlie did his in one day, but he has access to a shop, welder and big bench vice. He already had a RE XD 4.5 in SUA lift so he had the needed stering parts and brakelines. He used an old saggy set of stock wrangler springs (from the JY) and then cut the spring eyes off of some rear ford ranger mainsprings (also saggy, and negative arched) and placed it on top of the wrangler spring pack to help control spring wrap. It works nicely. He also cut off the old perches and re-used them, make sure you get the proper angle when you reatatch them. You will want to lots of research BEFORE you start this. But the average person with a welder and some tools will be able to do this in a weekend just like any other lift. IIRC he was into his @ $130, but like I said, he already had everything but the junk yard springs, ubolts and the ranger mains I gave to him.

I did an axle swap at the same time as a SOA, but the process is the basically the same.

i would go with a standard suspension lift, and when you come across the beefy things like axles and motors, then go for it. but any how, its your option..if you have time and money, go for it.

depends on the type of wheeling you will be doing, if you are just going to hit the trails every so often, then SUA lifts are your thing.

But if you are going after serious flex, softer ride, and will off road this often and looking to run 35+ inche tires then save your money find the right axles, and start buying the needed items and go SOA.

I have researched this to death and I have come to the conclusion that SOA will cost me only a bit more than the 4-5 inche SUA lifts that I was looking at.

4-5 inch SUA I was still going to have to install SYE / CV rear and then run the risk of an even stiffer ride on road, and potential lose of flex out on the trail.

I have an axle swap for the rear planned all ready so it only makes sense to go for it.

RE sells a complete SOA kit includes the extended brake lines, I will use my existing 2" springs may end up removing a leaf or two to stay around the 5-6 inch lift range.

I purchase my jeep with the lift all ready installed, but looking into this and what the SUA kits cost it just did not make sense to me to spend the money only to find out that I may want/need more lift anyways so I will wait it out and make my move when all the parts are collected.

Just my take based on the research that I have done on this site and others, there are so many posts on this topic that you start to see all that has been done and that some are content with their SUA, but most wish they had done SOA.

Alrighty, so i cant keep everything stock, and use it as a cheap lift, as i was planning. Its a beater Jeep until I start working full time, I'm not looking to spend an arm and a leg, i just want a cheap lift to beat off roading, I'm also planning on 33's
So if this is not a "cheap lift", what is besides a body lift?
Orrr, is there such thing as a "cheap lift"?
