I always see people that have AWD or 4WD ss's

Is that not an option for the 2006 model or something? if so did 2005 have it?

when i go to build and price a 2006 ss it doesn't have a package or option anywhere for AWD

 

The Silverado SS's only come in AWD. SO thats why they come in AWD

 

Starting in 2006 the SS is available in 2wd or awd.
