ZJ lift?

[85zebracherokee]

I was wondering do you have to put a slip yolk eliminator kit on a grand cherokee with a 4.5" lift like you do on an XJ or not? None of the lifts for a ZJ I've seen say anything about it, and what if you have the NP242 awd case? but after 97 the front drive shaft requires modification?
I'm looking at buying a ZJ but want to know what I'm getting into.
And What are the biggest tires I can run?

And 1 final question. Does anyone know if you could get the 5.2 grand with the 231 tcase?

not sure about AWD and 4.0 combined, but the biggest recommended tires on a zj are 35's. only problem is that 4.5" of lift will realisticly only allow you 33's. so to run 35's, you really gotta know what you're doing.
