SOA vs SUA

ok, once again i'm preparing for axle swap. i'm dead on money and i'd like to do it soon, but i want to make sure its good to go in the long run and more advantageous to me. I was planning on doin the SOA while i was at it, BUT seeing as how i'll need a SYE, new driveshaft and ideally an antiwrap bar along with new shocks, i'm thinking about just leaving it SUA for the time being, and later on this summer just gettin some 4.5" springs from RE to clear the 35's that will be on there. i feel my lift now will clear the 35's ok, but not very well once i get to flexin.

QUESTION IS: when you go SOA does it increase the the flex, or just the height? my leafs are already kinda saggy, so they'd need replacing eventually anyway, and at this point i wouldn't HAVE to buy the new driveshaft and shocks at this very moment. if SOA does increase flex i'd probabaly wait a while and jsut go that route

ps. i searched a lot for this but so many threads came up irrelevant to this and i was tired of reading through them and never could get an answer, any input is appreciated.

When I went from a POS 4" SUA lift to SOA on factory springs, the increase in flex was substantial, and ride quality was vastly improved. However, my 4" springs were stiff as hell, other brands of better quality should flex better than what I had (BDS, OME, etc....) Using 4" springs on SOA will give you a pretty tall ride, though.

I'm switching to some RE 1.5" springs made for SOA use. The factory springs that I used to get my SOA swap on the road were shot.

good info .. if i did do the SOA i would use the factory springs, i would not get the lifted springs becasue like you said that would be super high and i'm not in favor of tipping over every turn. also i've got a buddy with an XJ sitting in his yard not running, from what i've read the D30 in those is identical to the YJ (his XJ is a 94), and he's got 4.11's which would match my 8.8 4.10's great and would be a ton cheaper, i can probably get it for about 200 bucks with the front suspension included, and mount that up, so i guess i'm starting to lean away from SOA for the time being. maybe later on do like you did and get just a 1.5" SOA leafpak and i tihnk that would be a pretty sweet setup.

Wife's Jeep is SOA on new, stock height springs, 1" shackles, 1" BL, 33" tires. It measures 29.5" from level ground to the bottom of the rocker panel measured at the door area.

wow thanks stinger, awesome pic, i'll probabaly just go SUA for now to save some money, but thats not to say i won't always stay SUA, is there any real advantage (besides cheap lift), to go SOA? either way i'll need new springs eventually, so seems to me not having to make or buy an antiwrap bar and worryin about more stuff breakin and the money it wail save me now (laid off college student), i might as well stay SUA.

I'm pretty sure one of the above posters said the quality in the flex department substantially improves with SOA. If you plan on lifting i would save your money to eventually do SOA, if i owned a yj i would never spend my money on a SUA lift.
