in that and normal 4x4?? does the z-71 have heavier duty parts??I am asking this question because i have a white 1994 gmc ext cab 4x4 and my freind has a 1994 white ext cab z-71 and they are the exact same truck!! except for the grill and his says z-71 and mine says 4x4.I am pretty sure chevrolet started z-71 in 1989 but i am beginning to think gmc didn't start using it until 1995 or 1996 because i have never seen a pre 1995 gmc using the z-71 badge.
also i forgot to add to my freind's truck discription that it is a chevrolet not gmc like mine.sorry for any confusion....
ok guys you are only answering part of my question one thing i really wanted to know is if gmc started using the z-71 badge several years after chevrolet.
