Now you are thinking. Do your homework , most all lift height has ramifications , and the higher you go , the more you have to change. I know first hand.
Each TJ seems to work out a little different , but in my experience up to 2.5" and good components, 31-32 inch tires is a smart move , 33" and 3-4 inches looks good and means a regear, adjustable control arms, adjustable track bars, new sway bar links and possibly SYEand /or CV drive shaft (there's more to it than that , just a general statement) a transfer case drop may be needed and a few more tweaks....35 inch tires are generally all this and big brakes, heavy duty steering is a good idea and bigger axles...so with the tires and wheels you spend around 10,000.
You can skip certain steps, but not without consequences along the way.
@Jerry Bransford and @Boogieman know the territory , don't take all I say as gospel, I'm just giving you the general idea.
One of mine is lifted 2.5" and one is 3.5", the amount of changes is dramatic. The 2.5 is more pleasant if you daily drove it, the 3.5 looks tough and had been a job to get dialed in.
