you can get them either way. the 249 transfer case only has 4wd high neutral and 4 lo. mine has the 242 case, it has 2wd, 4 hi locked, 4 hi unlocked, neutral and 4 lo. the 249 case is actually stronger by what i have been told, but has a flaw. there is a piece called a vicious coupler that has a tendency to go out around 15000 miles, but can last longer. to replace the part is about $300~ which is about the same as puttin a different transfer in. if you do get one, feel free to ask questions after you search, and post pics. we were all newbs once.
