Single VS. Dual

[Sneeck]

Dually gives way more torque, your driveline has to be bullet proof.

But a single is almost just as powerfull, only with less torq(still enough to cause driveline problem's if these aren't upgraded). Looking at the 9xl on 18 cell's does get you allot of speed and torq, you won't need a dually. But it is darn cool lookin IMO.
