Brett hit everything pretty much right on the head. Not bad for a TJ guy
A SOA with stock springs should be just about right for 33s, around 5-5.5".
I ran 5" back in the day with 33s and that worked out pretty well. An SOA with stock springs is not to much lift for 33s. I had to go with TJ flares and used a cut down 3" BL to clear 35s (also have a couple extra leaves in the spring packs)
Having run an SUA for 2 years, and an SOA for almost 3...a SOA done right is definately the way to go IMO...Rides better, flexes better, etc...wish I would have gone that route right from the start. I've never really had any death wobble, and I usually drive it 300 miles at 75-80mph once a semester just to get home...and to Katemcy several times, and it handles fine at highway speeds
Like Brett said, you should do a SYE at the same time. I've seen people skip that step and get away with it for a little while...but I definately wouldn't recommend it.
I also trashed the front sway & track bars a looonnnggg time ago. But Disconnects wouldn't be a bad idea. The only other thing I can think of is that if you get alot of axle wrap in the rear, it might be worth looking into a traction bar or similar setup, but you'll probably be fine. Oh, and don't forget the brake line extensions
I just finished my 3rd test this week and my brain is fried. If you have more questions I'll see what I can come up with
