Question Quadra-Drive II vs Quadra-Track II

I'm trying to decide if Quadra-Drive II is worth the extra cost vs. the standard Quadra-Track II on the Overland. I don't plan on doing anything too extreme off road, but I do find myself in the snow, mud, and sand now and then. I'm one of those guys who may not need it, but likes to know he has it just in case!

If there is someone with experience using both systems off road I would love to hear your comments.

Thanks,

Bruce

Re: Quadra-Drive II vs Quadra-Track II

I went off road with Quadra Track II and it performed beautifully.

The question you need to ask yourself really, is whether you really need the V8 or the Diesel engines or whether the V6 will be enough for your needs. The transmission choice rests in reality with the engine choices.

Re: Quadra-Drive II vs Quadra-Track II

Thanks for the input. I'm also trying to decide if I want the fuel economy of the V6, or the power of the V8. I'm leaning toward the V6 so long as I'm not giving something up with Quadra-Track II. I don't think the extra cost of the diesel will be worth it to me.

Re: Quadra-Drive II vs Quadra-Track II

While QDII is a fantastic 4WD system I can honestly say I got through this last winter just fine with the V6 and QTII that I have now.

Re: Quadra-Drive II vs Quadra-Track II

I went from an 05 Hemi with QD2 to a 14 V6 with QT2. In auto mode it didn't feel as sure footed in snow and ice; however, once I used the selecterrain dial and switched to snow it did just as well...

Re: Quadra-Drive II vs Quadra-Track II

There's no doubt that the QDII is more sure-footed on snow and ice. If they offered it with the 3.6L I'd most certainly have it. It's by far the best 4WD system I've ever used.

I've never taken my SelectTerrain out of auto... I had no problems on ice or snow with the QTII. There is a little more wheel slippage under certain conditions but you just need to adjust your driving style for it.

On my 02, the QDII used a gerotor coupler in the transfer case and in both the front and rear Vari-Lok axles. It was capable of sending engine power front to rear and side to side. As long as one wheel had traction it could receive 100% engine power. That is not true for most other 4WD systems on the market.

On the WK2 QDII, it looks like they've eliminated the gerotor couplers in favor of a rear-only ELSD used in conjunction with electronic traction and stability controls.

I haven't driven the QDII on the WK2's so I don't know how favorably it compares to the QDII I had on my 02 GC.

Re: Quadra-Drive II vs Quadra-Track II

Take a look here. It will compare the 2011-2013 QT2 with a traditional QD2 on the previous gen, which had (correct me if I am wrong) LSDs in both axles. Then keep in mind that the 2014+ have a different transmission with improved ratios and more advanced electronics - which in theory would make the QT2 even better.

Thank you, this video was perfect! Especially since I currently own a '05 Liberty Limited...I guess I wouldn't have made it up that hill...

I'm not sure what that has to do with my initial question, but thanks for your input.

Quadra-Drive II vs Quadra-Track II

My advice would be that if you can afford it then the QD2 is a nice addition to have. That being said, the QT2 is still excellent and will serve you well also.
