I AM CONSIDERING BUYING A 94 GRAND CHEROKEE WITH A 4.0.  I WILL BE DRIVING ON OLD LOGGING ROADS, MOUNTAIN ROADS, AND NEW MUDDY WOODS ROADS IN THE NOUNTAINS.  
HOW WOULD THE JEEP DO WITH A 4 TO 5 IN LIFT? DO YOU KNOW OF ANY MAJOR PROBLEMS WITH THE 1994-96 MODEL YEARS?  THANKS FOR ANY TECH HELP YOU CAN GIVE.  

I don't know of any major problems with the ZJ (93-98) but I don't own one yet (I am looking for one though).  What size tires do you want to run?  Check out icelandoffroad.com, they have some nice fiberglass fender flares for the ZJ, and fiber glass front bumber with winch mount.  For suspension, teraflex.biz has what I consider the best suspension system for the ZJ.

When you put on bigger diameter tires, be sure to regear accordingly.
