Quadra Drive II vs. Quadra Trac II

Did you guys realize that most of you are probably buying a Limited or Overland and they come standard with the Quadra Trac II and not the top of the line Quadra Drive II. Correct me if I am wrong, but it used to be when your ordered a WK Limited or Overland you not only got the skid plates standard, but also the Quadra Drive II which is a superior 4-wheel drive system.

Yes we know. We can get QD only with V8 not V6 though.

Re: Quadra Drive II vs. Qudra TracII

For the USA:

I don't believe skid plates are standard on any WK2, only available in an ORA package.

QD has never been available, let alone standard, on a V6 WK2.

In 2011, QD was standard only on the V8 Overland and Summit, not the Limited. The QD option was restricted on other models most of the year, however. In 2012 only the Summit V8 has QD standard. QD is in the ORA II package for V8s, however, and not as much restricted.

QD is better, dunno about how superior now that they don't put ELSD in the front diff.

You also can't get QD2 without air suspension, :-(

That's why I am going with the ORA II. My point with this thread was that these features and upgrades came standard with my 2005 Hemi Limited, now you must piecemeal them together to get the skid plates and the QDII.

Re: Quadra Drive II vs. Qudra TracII

Maybe I don't understand the how both QDII and QTII works but something about the audio explanation between the two systems on the link above doesn't make sense.

The guy explains in the QDII system says that when 'traction is lost' in any of the wheels that the QDII instantly transfers all of the torque to the wheels with the most traction.

However in the QTII system audio he says that QTII instantly transfers torque to the 'slipping axle' which implies to me that the wheels with the least amount of traction are getting the boost in torque.

Is the audio incorrectly describing what should be happening in QTII? It makes no sense to me to transfer torque to an axle that is spinning.

Re: Quadra Drive II vs. Quadra Trac II

It appears the audio is not correct

"QTII instantly transfers torque to the 'slipping axle' "

Both QT II and QD II use the same transfer case which has a limited slip diff internally, so if your from wheels (i.e. front axle) do not have traction, the case can send nearly all the torque to the rear axle. The system uses brake traction control between the wheels on the same axle to minimize the spin of a wheel without traction and getting more torque to the wheel that has it.

QD II adds a limited slip diff to the rear axle, so instead of using brake traction in the rear, the diff does the work.

The front diff is open regardless.

Re: Quadra Drive II vs. Quadra Trac II

Re: Quadra Drive II vs. Quadra Trac II

That's why I ordered mine with the adventure off road pack as part of that pack is the inclusion of the quadra drive II system

That is also why I did the same. There was not one with the ORA II in my state when I bought so I ordered it. Did not necessarily Quadralift with my Limited, but am glad I did now.
