I think SOA lifts are cool, have seen several CJs and YJs recently done this way. Personally I didn't want to go SOA, thought it to be too much lift and too pricey ultimately...gets into how much stress stock axles, diffs, and bearings that have 123k miles on them can take with over 33 inch tires. Not only that but wouldn't that pretty much mandate SYE and longer driveshafts? If I did this I'd want to build up the axles and everything you can't see first, which by any estimation would put the work out of reach of the $600-$800 budget I've got working for the lift doing the work myself.
Also since I don't know of any good offroad shops in my area, I have grown uncomfortable with the idea of some hack not setting the perches right, and I can't do the welding myseslf. Of course, the SOA is cool because it does allow you to help set the pinion angle....but generally too much of a build for my first go round. Maybe we could build up to that one day.
Right now I'm looking for something more mild since this will be the first time I've lifted a truck and have a thin budget. Good thought though, if I am missing something on the SOA let me know.
