    Default How much bigger is the new Silverado?

    I have a 07+ silverado Xcab with the standard bed I was wanting to know if anyone knew how much bigger these trucks are compaired to past generations. I had a 1989 Chevy truck that I put a soft bed cover on, then sold the truck for a 2002 GMC Sierra & put the same cover on it, I t fit rather well only problem was the bowtie stiched into the cover on a GMC lol. But was wonder if that cover could have fit the newest trucks? Would try it out but sold the cover years ago. But older style parts are easier to get at cheaper prices, so would this be an interchangable part? I'm sure the fiberglass hard style covers would not fit because they are formed to the beds. Thanks if anyone has the measurements of these trucks that may help. Also I read before that due to the brakes on the new 07+ Silverado the smallest wheel you can get is 17 in. which who would want to go smaller but is this right? Thanks again.

    My NNBS bed is somewhere around 8" wider than my father in-law's '98 and I want to say that the '98 and his '03 are just about the same width in the bed. Riding in the cab of his '98 and then in my '08 is a big BIG difference in room.

    I was tuning a 2011 silverado a couple weeks ago, and I was impressed how smooth the truck was, and how well the brakes performed
    The owner added a supercharger and a lift kit and it didnt drive like a truck
