Come on Guy's, that's all you have to say about the Overland??????????

Listen to me fellas! I have one of the most capable Jeeps on this forum. I have a ZJ!!!!

Having said that, I will now tell you why the Overland in its stock form Is more capable then any ZJ ever built. not only the ZJ but any other WJ and most Jeeps in the fleet. (just not the Rubicons)

Remember this, Traction is King.

Your traction system is better then any Limited slip or Trash loc that the ZJ had. Your system takes it a few steps past just a limited slip diff. granted its not a locker but it sure performs damn close . All the torque and power means precisely **** if you cant put it to the ground. Not only does your jeep have the awesome 4.7 HO. but it has the means to put the power from the ones that slip to the ones that grip. And that my friends is what makes it an awesome stock Jeep.

Here is a little info on your Vari-loc traction system.
Vari-Lok progressive front and rear axle differentials. This system has the ability to keep Grand Cherokee going even if only one wheel has traction. Incorporating a speed-sensing torque transfer differential, Vari-Lok provides a major improvement in wheel traction compared to other four-wheel drive systems. Under conditions in which opposite wheels are on surfaces with widely different friction characteristics, Vari-Lok delivers far more torque to the wheel on the higher traction surface than is possible with conventional limited-slip systems.

The gerotor pump incorporated in the Vari-Lok differential is conceptually the same as that used in the Quadra-Trac II transfer case. Its operation is virtually undetectable by the driver, but the Grand Cherokee's ability to maintain headway and control under low-traction conditions, both on- and off-road is very evident.

Power transfer in a Vari-Lok differential is proportional to wheel speed difference rather than torque difference as is typical in most mechanical limited-slip systems.


So I am thinking Hell Yes! the Overland is an Awesome 4x4 in its stock form.

Vari loc is just q diffrent kind of limited slip, nothing special really. About half as good as a real locker. Stock they work good, 32" tires and up they get overpowered and perform like a open diff. Don't beleive everything you read. I have owned my overland for 5 years, q-drive is great for stock rigs or on the street but not even close to lockers.
