As for TJ components... you will get less lift. I ran 3" TJ coils on my ZJ. Gave me around 2" of lift. Maybe a tad less.

Also, I may recommend AGAINST a dropped pitmant arm. If you are using the stock trackbar locations, changing the pitman arm will pull the draglink out of line with the trackbar. Those two being out of line will cause funky things to happen. This is from experience. They are used alot on TJs because some of the TJ kits use a new frame bracket that lowers the mounting point. If you did the same on the ZJ, then that would be cool.

I'm curious as to what longer upper arms you mean. Do you mean Adjustable arms or a full Long Arm kit?

There isn't much difference in 32's and 33's. Most 33's have a running hieght around 32" anyway. VERY few tires actually run at their stated size. ;-) A mag somewhere did some tires evals and listed many that were nearly dead on their stated size, but a lot more that were as much as one inch smaller. Something to think about.

You also should not have to change your driveshaft until you start changing your suspesion components. Example: adj control arms. Depending on how much you adjust. Long Arms would be more likely. I think that if you do some searching, 4" is about the max to go with standard arms. I found that with 2.5 or 3" so of lift, the travel was limited signifigantly by the lower control arms front and rear. swapping to aftermarket arms let it drop about 2-3" more.

I have longer lower control ares that came with my kit. also I have the drop bracket on my trackbar also came with the kit. I do however have a HD ajustable trackbar and new hd frome mount in the mail as I type this from rusty's offroad.....
