I read somewhere that those items were required to allow the vehicle to tow up to its 3800lb capacity and came with the towing package. Without it..you are stuck with the 2000lb limit of the vehicle itself. Id have to guess its some sort of airbag/rideheight suspension adjustment doohickeymajigger.

 

Will the AWD system slow down the 0-60 time as opposed to the RWD?

 

I bet it will because of the added weight of the system. Perhaps not by much so in everyday life it might not make a huge difference but off from a standing start, the AWD should be slower.

 

I'm thinking of an AWD because I plan on supercharging later, wouldn't the AWD help plant the car if it develops near 500HP.
I'm afraid that if I supercharge a RWD RT, the extra power won't matter because of the traction control system that will cut back power if the weels spin a little, as they surely will with 500 HP, what do you guys think?

 

Good points...

Let's see, I guess the RWD traction control would cut back a lot of power indeed, but that's only for the split second it takes for the Magnum RWD to start moving without wheel spin. As soon as it has started moving, the full 500 HP will come into play and it will be propelled forward as hard as the AWD. So the advantage of the AWD might only be during that split second where traction control of the RWD is cutting back the power at the start. And all things being equal, the supercharged AWD will still weight more than the supercharged RWD at the end of the line.

But I am purely speculating here, somebody could have a different view on it.
