Difference between Quadradrive and Quadratrac?

And what is best for what purpose?

I own a 1998 ZJ 5.9 fitted with Quadratrac and use it solely on the road by the way...

Quadra Drive System and Vari lock axles was an option on the 1999 (WJ). Basically, it is an all wheel drive system with a lo range, no 2wd option. The vari lock axles shift pulling power from one wheel to another depending upon which wheel has the best traction. I think the WJ's use the 247? Transfer case.

Well, for one, Quadradrive was only available on the WJ and WK.

The difference between Quadradrive and Quadratrac II on the WJ was the addition of Vari-Lok limited slip differentials in the front and rear on Quadradrive. Both systems used the same NV247 transfer case.

I believe WKs used electronic LSDs instead.

As for the ZJ, there is a chance you have a rear limited slip differential, which is about as close stock as you would come to Quadradrive.

Yes indeed I have the LSD-option!

Used to run my previous 5.9 RWD and although the steering improved (smoother I guess you could say) and the car was quite a bit faster in a straight line, I do prefer the surefootedness of the 4x4 system in the rain and bad roads.

Speaking from experience, my 00 WJ with the Quadradrive system loves the ice and slick roads. When it was new, I wheeled it some. Traction never seemed to be an issue, ground clearance and too much sheet metal were issues. I own three Jeeps (WJ, XJ, & a TJ)... on snow/ice covered roads, the WJ is by far the best of the three.. I mean the other two don't even come close.
