Question spring over axle questions

Hey guys, i was just wondering if you could tell me a little about SOA lifts, like how they work, what all you need to do them, how much lift you would gain by doing this, and roughly how much would it cost to do a good SOA. Thanks a lot
-Sam

Well you'll have to cut the old brackets off where the leafs sit on then weld new perches on the top. You should gain bout 5-6 of lift. Your going have to buy longer brake lines new shocks new u bots have your front drive shaft lengthen, and best bet is to get sye for the rear and turn you rear axle up so that its in line with the transfer case. Your gonna also need to get a new drop pitman arm. I think thats bout it or atleast thats what i did. Oh and good luck

You'll have to address your steering issues when doing a SOA lift.

soa is sort of taboo, but i really don't know what taboo means. there's a lot of people doing things that shouldn't be done, and then there's ways to do things right.

if you don't have welding and fabrication ability, its not the route to tackle on your own. i've seen some really scary soa's.

pinion angle, steering geometry and axle wrap are the main points that need to be done/addressed correctly. also consider spirngs, soa on 20 yr old springs is a bad idea.

the steering is the biggest hurdle i think. and if your spending the money why not buy the high steer kit. but like they said its going to be like 1k at least

I would say that if you are doing a SOA to save money on a SUA lift, you are wrong. As previously stated in others' blogs, there are a number of things that will need to be addressed in order to have a quality SOA lift that performs as well off-road as on.
This is the list of what will need attention:
1. Spring pads welded to top of axles
2. New u bolts
3. Longer brake lines
4. Longer shocks
5. Extended front drive shaft
6. SYE/shorten rear drive shaft (highly recommend CV)
7. Get the diff angle right prior to welding/center line also
8. Quality springs that are engineerd for SOA last longer that stock (RE sells some good ones with reverse spring eye)
9. Steering will need to be addressed
10. Build/buy a traction bar and install correctly to prevent axle wrap

I am sure there are more things but these are the majority. I have run SOA on my YJ for years now and love it. It does come with it's pros and cons, but doesn't everything?

Happy Wheelin,

Mike

Finally!! Several voices of reason. So many people think "I can get 5 inches of lift really cheap." These are great reason why SOAs aren't all that cheap. There's no such thing as a free lunch & that includes lifting a Jeep. Don't get me wrong; a properly built SOA can out-perform a SUA, but if you are just getting into Jeeping it isn't the route to take. You can get several good 4" lifts for half the price of a SOA & still retain the stock handling characteristics.
