Purpose of a 4 speed Transfer Case

Okay, so I'm not too terribly offroad savvy. So I just have to ask, what's the purpose of a 4speed transfer case, I'm sure it would be cool to have and use, but I don't know the TRUE function. So if someone could enlighten me, that would be great.

Thanks

It just gives you more options. Essentially, you can run your front end separately from the rear and you get two different low ranges - a low and then a lower low.

Well sort of. One can operate in just the front axle depending on the t-case. It is not 4-speed specific. The Atlas 2 speed does it too. It is a shifter positioning. Twin sticking and dealing with interlock on cases such as the Dana 300, Dana 20, NP205 (usually a gear drive case has this possibility), can achieve drive axle selection.

The choice of 3 different low ranges is nice for when you drive on a variety of terrains. I have 2.7, 3.8 and 10. The 10, or "Stupid slow" I find is really nice for times when you want to go as slow as possible. Awesome for using the gas as your accel and decelerator that I find superior to wheel brakes in slick conditions. The 2.7 is nice for that light wheeling and the 3.8 is nice for crawling.

I think I have used the front dig once or twice in the 5 years I have had it. Depends on your wheeling.

:sigh: Yes, this is true and no, it isn't 4-speed specific. My Atlas 2-speed will do this as well. I didn't recall the OP asking about an Atlas 2-speed nor am I aware of a Dana 300, 20 or NP205 being an option for a JK. This is after all, a JK question in a JK tech thread and if you had one, you would know that you can't just go around sticking any ol' transfer case you want on it especially if it is a newer one. Either way, I guess I should apologize for not being more thorough by adding in information that really isn't relevant to the question at hand. :rolleyes2:
