i herd couple differnt speeds i just wanted to know how fast you can go in 4wd befor messing anything up

 

why would you want to go fast in 4 wheel drive ???when im in 4 wheel drive im eather in some sh*t weather where i dont want to go fast or im in some mud and all the tires are spinning and to busy looking ahead so i dont hit a tree.

 

I think the only thing the manual says is you can't shift into 4wd any faster than 55mph, but I don't think it says a top speed. However, since you are supposed to use 4wd only when it's slippery out to help with traction, common sense says you shouldn't be driving very fast.

 

A proper question for a 4x4 owner is not "How fast can I go?" (nor should it be a question for ANY truck owner, unless your name is 94rt10ohio ).

More appropriate questions would be:

"How deep does the stream need to be before I should worry?"
or
"How many logs can I cross before I blow a CV axle?"

thanks for the help guys, it was more of a question towards when you are on the highway and it is snow coverd, most people are goin 100-120 kph i just wanted to know if its safe to have it in 4wd goin that fast cus on my old truck it was only good to go 80 kph

 

I would contact your local dealer to confirm that speed. they should know.

 

I can tell you this. KRC Performance by me has modded the hell out of some Quadra-Drive SRT Jeep Grand Cherokees. They have done a couple that push 600 HP and live at the track.
The QD system basically is always in 4WD and has automatic lockers in both differentials, resulting in immediate "hook-ups" off the line, giving a tremendous advantage.
I know the engine & tranny are modded, but I am pretty sure the transfer case is stock. So I would say if their stock Chrysler transfer cases can handle it, you shouldn't have too much to worry about...

 

It's 4Lo you need to worry about going fast. You can simply look at your rpm gauge to figure that out. I think it's around 35mph for 4Lo, but I was just out cruising the last snow storm at 80mph comfortably in short bursts.... Hey, I had places to go!..lol
4Hi works like a normal differential. You don't even notice your in 4hi when your on the highway or at any speed for that matter.

 

The truck can probably handle it, but if there's a reason to use 4wd on the highway, I personally wouldn't be driving 65-75mph (100-120km/h). I see people driving Jeeps and other SUVs going that fast all the time on the highway - but remember that most of those people are idiots and think that 4wd means they are indestructible, until they spin out into a ditch. If it's slippery out, you should be slowing down whether or not you have 4wd. The people who don't are the ones that cause all the accidents that come every storm.
