Hey guys, so my friend bought a new 2010 Liberty and he asked me what the max speed was in 4HI, and I told him about 55mph.. I said that assuming they didn't change the systems too much.
I'm not 100% sure which transfer case he has, but I'm assuming its the Command-Trac.
The dealer told him 75mph.. I Love Jeeps, and the Jeep brand, but I feel the sales person is still a sales person and doesn't know that much.


Thanks in advance.

I came back from the cabin yesterday, got home 250 miles later and realized I was in 4X4 no wonder my mileage dropped to 20.3 mpg. I ran 75-85 MPH all the way home. No problems.

Hey there! Put your Jeep info here!

4WD HI can be engaged up to 55MPH but you can drive any speed in 4WD HI, Granted you probably shouldnt be doing over 55 MPH if you need 4WD though lol

I would say good call on the 55 mph, if you need 4wd then you shouldn't be going that fast anyway

From the Jeep FAQ page.
"Can I shift into 4WD High Range at any speed?"
"Shifting into 4WD High Range can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 55 mph (88km/h)."

"How fast can I drive in 4WD High Range?"
"You should not go faster than road conditions permit."
Check out the above link. Good info there, straight from the Mfg.
