Short answer: RE 3.5" lift kit
I have a Rubicon Express (RE) 3.5" superflex kit (4.5" superflex kit but with 3.5" springs). I bought it as a package deal from 4x4groupbuy.com and along with the lift kit the package came with an AA SYE and a Tom Wood's rear CV driveshaft. I'm still kicking myself for not getting after measurements, but most will tell you RE's 3.5" lift will get you closer to 4" or slightly higher. It's plenty tall for 33" tires (285/75/16" is what I'm running).
Included in the kit were fixed lower control arms, adjustable upper control arms, 3.5" springs (of course), adjustable front track bar, rear track bar bracket (still needed to buy an adjustable rear track bar to center the axle), bump stop extensions, longer front brake lines, sway bar disconnects (which I sold to help pay for the Currie Antirock), and I'm probably forgetting some other minor stuff that came with the kit. I also purchased four RE shocks & boots, and rear axle shock mount extensions (I believe by teraflex).
I later replaced the rubber bushings in the control arms for some poly ones by Daystar; I think they're now sold with the poly bushings. Not that they were going bad; I did it because I could. I've been happy with the suspension kit. I think it's a good middle-of-the-road lift kit; an upgrade from the cheap lift kits you can buy out there, but I'm sure if you want to spend the bucks you can go all out.
But to bring it back to the original topic: with all this lift and bigger tires and body armor and such (added weight), driving it would suck if I didn't have 4.88 gears in the axles. It's the 4.88 gears that make it all work with the four cylinder engine and 33" tires.
When we were in Alaska and Canada we had a GPS that gave us our mph so I could compare what the speedometer said compared to the GPS. With 33" tires (285/75/16") and 4.88 gears, when the speedometer said 65 mph the GPS said I was doing 62. Close enough.
