Look at the Teraflex lifts if you're on a budget. You can do a budget boost lift for $500. I'd recommend getting a lift that includes new springs at least. You can reuse your stock shocks with brackets. I have a 3.5" lift on my Jeep and have not had any issues with needing a drive shaft and I didn't need anything that you wouldn't need with a 2.5" lift. However, I do have adjustable front upper control arms. You can keep it cheap and get some geometry correction brackets for your lower control arms and that will correct the caster on your front axle. They hang down a bit but work just fine. The above poster is right though on your 3.8L motor. It's kind of a dog. Unless you have a Rubicon with 4.10 gears, it's going to be a slug. Even with the 4.10s, it's still going to be kind of a pig with 35s. If you have 3.73s you're not going to enjoy driving it on the highway. If you have the 3.21s, you'll hate it. Regear is not cheap. A buddy of mine just paid $1,800 to have his done. You will also need a programmer like the AEV procal to adjust your computer for new tire sizes or axle ratios. I paid $160 for my Procal. Also, I have 35" BFG KM2s on my Jeep. But when I measure them, they're only 34" tall. I'm not sure if their A/Ts are the same way, but I'd guess they are. Whatever you do, it's not going to be cheap. If you just did four tires and wheels, you're still looking at $1,500 at a minimum and that's with about as cheap of wheels as you can find. A cheap ass budget boost is going to be $500 at LEAST. Add in the other odds and ends you didn't think of like geometry brackets, programmer, TPMS sensors, etc. and you're looking at $2,500 for a cheap lift with 35s and that's before a regear if you need it and you likely will. People drive them like this all the time though.
