I think depending on package there are both 17" steel AND aluminum stock wheels. But there are A LOT better choices out there A LOT cheaper.

I know Mickey Thompson and Dick Cepek wheels have long had a reputation for excellent strength to weight ratio...

 

Yeah i'm really not sure if im hardcore enough to drop the truck. I have never been fond of trucks that sit that low to the ground, just doesn't look right on a truck. I love the way my truck looks on 20" wheels but i would like to have the extra performance. If i decide that its worth the sacrifice ill likely goto 17 or 18" alluminum.
