I currently have a 2001 Grand Cherokee Limited with Quadradrive. I do some off-roading and have been impressed with the Quadradrive. I am considering a Commander and want to know how the QT2 compares to my QD1?

Would you also like to compare the QD2 ?

Your going backwards in performance to the QT2.

 

[kjpeaco]

That is what I needed to know! I wasn't sure if my QD1 is comparable to the QT2 or if the QD1 is better. So you would rate the systems from best to worst being QD2, QD1, QT2, QT1?

Good info here....

"The Quadra-Drive system was introduced in 1999 and is based on the Quadra-Trac II system but adds limited slip differentials to the front and rear axles to create a four-wheel drive system capable of not only directing torque to the axle with best traction but to the individual wheel on an axle with best traction."

You have them in the correct order. None of them are bad but Quadra Drive II is amazing.

So if you had the choice, which one would you get (both are same price)?
2010 Sport QT2 with HEMI, nav, leather (Sun and Sound Group) and 44k miles
or
2008 Overland with HEMI, and 84k miles

I'm almost positive all hemis are QD2.

Not in 2010

Just my .02 but I think the QT II is better than the older grand Cherokee quadradrive. Again just my opinion. However your grand Cherokee has a solid front axle and if lifted with bigger tires would be a beast!

All depends on what you plan to do with it..... but id get the 2010 that has half the mileage. You can swap in a QDII front diff and a mechanical locker for the rear if you want to do hard wheeling. I actually prefer a selectable locker up front..... I dont like the feel of my front end binding while in 4low on trails so I normally wheel in 4hi.

That's not true. The first year (2006) all Limiteds had HEMIs and they all had QDII. After that QDII was an option.

I have a little lift with 265/70/17's and bilstein shocks. I recently took it all the way through Kane Creek Canyon Trail in Moab.

Over the last few days I have searched on here about the rear lockers and can only find dated threads that end with people saying, "So who is going to try this and see if they do work with our setup".

What rear lockers will work with the rear diff? Any links to a good thread?

07JeepXK has done it with a write up on another site. He also installed a QDII front diff to lock the front with an independent switch.

Go and search there.

Here is the install on the rear locker by 07JeepXK:

What are the pros and cons of the Powertrax No Slip? Would it impact my daily driving at all? Does it work a lot like the QD2 for the rear? Are any other modifications required/suggested after doing it?

 

[kjpeaco]

I have now read all of 07JeepXK's thread on the other site and understand how the No slip works. Being that it is locked all the time while driving straight, does that put added stress on the system? Does it impact gas mileage? Void powertrain warranty? With a locker, is their any added maintenance?

 

[07JeepXK]

Hands down get the 2010 hemi and if you plan on off roading just add lockers. Total cost was $1500 to lock front and rear of my commander. No negative effects from the no-slip. Honestly you won't even realize its installed. Well until your tearing up the trails. No added maintenance needed. It won't void the warranty if they don't know it's in there lol

 

[kjpeaco]

Thank you all for all of your help with this.

Anything I should really look for prior to buying the 2010?

 

[kjpeaco]

I have been looking on Summit Racing and they only show that the Powertrax is for years 1997 - 2009. Did something change in 2010? Or have they just not updated that part of their website?
