blazer51, BDS also makes a 5" lift that most any one can istall, no welding required,
so you loose 1" of lift, with a body lift you can still clear 33"s, SAS is way to involving, and will more than likly cost almost as much.. plus the down time

 

I've got the 2.5" susp lift and I fit 31x10.5" w 1.5" spacers no prob. I'm going to do a body lift though so I can get 32s
