now thats not true...just think about it, your box is getting further away from your axle as you lift it higher meaning your drag link need to either be longer or you need to drop the pivit point(pitman arm) down to compensate for the extra lift...that is part of the reason I dont use Tuff Country anymore...no offense to your friend, but their Tech Support sucks...like I mentioned before, if you did a small enough lift you may be able to adjust the tie rod ends out enough on the drag link to compensate for it but I'm not positive how much you can adjust them out on a ZJ...it shouldn;t be a problem finding a pitman arm though...as far as I know the ZJ box is the same as any other Jeep...its just a saginaw style box and so you can use a pitman arm from a cherokee or a wrangler, it might take a little fab time but not much...
