Another lift thread. (Sorry)

I know people probably hate these by now, but there's way too much stuff to sort through and way too many specifics that prevent me from being able to search for my situation.

I have a 2001 automatic sahara on 31's. Currently, I have a 2 inch spacer lift from the PO. According to the guys at Just Jeeps of Texas, I'm only getting about an inch of lift out of it due to my factory shocks. On top of that, I want to get rid of the spacer lift because, according to almost everyone, it's only going to end up costing me more if I break something.

So, my question is, how big of a suspension lift can I get without have to replace my drive shaft or anything like that?

You need to go to another shop from now on. Shocks have nothing at all to do with lift. That is the job of the coil springs. Shocks just make the ride nice by creating resistance in the suspension to deaden bumps and keep the rig from continually bouncing after hitting bumps. They do need to be the correct travel for the corresponding lift though. Your lift may be limited due to old sagging springs, but nothing to do with the shocks. The most you can lift before getting into more mods with only springs would be 2". Between 2 and 3" you'd want to look into a motor mount lift to correct drivelines or drop the transfer case (don't do that). 3" and over an SYE and CV driveshaft should be used along with adjustable rear upper control arms.

I most likely misunderstood what they said. I just know something is preventing the 2 inch spacers from actually lifting it 2 inches

It may just be old springs. Have you considered v8 ZJ springs up front? They'll give between 2 and 3" of lift on their own without spacers. I ran a combo of them with 2"BB in the rear for a while before I got serious with my Jeep.

I'll shed some knowledge(or my experience/opinion, because I'm sure people can disagree or say I'm wrong) on lifts for ya. A 2 inch lift has very minimal effects on your stock suspension components and everything else affected by lifting the body and frame. You really won't need to replace anything, though your stock shocks will limit downtravel of the axle and tire, and bumpstop extensions would be good if you need to limit up travel( if your larger tires are rubbing or in your case you have spacers and the spring can be damaged from over compressing it). If you wanted to stick with 2 inch I would just replace the coils and take the spacers out.
At 3 inches of lift longer shocks become almost mandatory. The track bar will be at an increased angle and will push the axle off center to a point that is almost noticeable and control arms will bind slightly. An adjustable trac bar would be a good thing to invest in, but the stock one can be used without too much trouble, as long as your not replacing the control arms. The stock control arms will work fine. you should be ok with driveline angles but you may experience vibrations in the rear driveshaft, and it's a good idea to plan on either a transfer case drop, motor mount lift, or a slip home eliminator and cv drive shaft. Your brake lines should be fine mine were good with 3 inches but it wouldn't hurt to relocate the brackets to allow a little more length. They have kits for this or you can DIY. Pretty easy and cheap. And longer away bar links are must.
4 inches of lift is stepping it up to a whole new level, at least cost wise. Besides shocks and coils, you'll really want to get adjustable trac bars, new lower control arms to prevent them binding with the bracket, adjustable upper control arms to dial in pinion angle and to adjust for pinion angle in the rear if you get a SYE, brake line extensions or longer brake lines, sway bar links or quick disconnects, and some people get away with a tcase drop but a SYE is the best way to go. There are a shit ton of 4 inch kits out there. Most of them are the basic and only include lower control arms and trac bar brackets and skimp on everything. I've heard of so many people unhappy with the ones like this that I would be careful and not just buy the cheapest one. But if you want a 4 inch lift do what your budget allows. And don't think about lifting any higher than that without a descent understanding of suspension geometry. Lol
