Springs> I went through about (literally) 4 or 5 different pairs (F & R) of OME springs....never could get the LJ to sit level.
On advice of a friend, I went the Currie route, and I'm very, very pleased. Truck is level, and the truck's ride is pretty good (hey, it's a Jeep, not a Caddy).
While I'm on the Currie bandwagon.....as my friend says "All Jeep parts must be bought 3 times".....and that's pretty much the case with me
.... I've ended up with all Currie stuff, and my short arm Jeep just flat out WORKS. I'm very, very impressed with the quality, the fit, and the performance of Currie suspension stuff. It's freakin' expensive.....and worth it IMO. I woulda' saved tons of time and money if I'd just used their stuff the first time.
Currie rant off.
Yes, you can clear the 35's with a 4" lift, but you'll have to bumpstop the crap out of it. It's not the outer flares that you'll hit so much (I did have to trim mine 1")...on the front you'll hit the sheet metal flange where flare meets fender, and it'll indiscriminately sipe your tires for ya' (ask me how I know).....in the rear you'll hit the forward and rear corners of the wheel opening in the tub. All this was "fixed" with the MetalCloaks on my rig.
Now I run very minimal bumpstop, and have a great range of motion of the suspension.
That's my .02
