2005 Vs. 2008 K1500 Gvwr 6400 Vs 7000?

[kelkev]

My 2005 Sierra 1500 Extra Cab Z71 has a 6400lb GVWR, and the 2008 models I've looked at have a 7000 GVWR.....any idea what the differences are? Maybe just some new marketing? I can't imagine that, but looks like the same engine, transmission, and rear axle. Just curious if anyone has noticed this as well...

I am just taking a guess here but I think the NBS trucks are a little heavier then the OBS trucks. Also maybe because of the redesigned suspension, fully boxed frame, and other enhancements made to the NBS trucks they have a higher GVWR.

I believe that the body is thinner, thus leading to a slightly lower weight - but I believe there were other improvements as well.

The frame is also lighter (and stronger).

[jrrod2004]

is the frame made up of steel???

Uh, yeah. But it lost weight and gained strength due to more use of Hydroforming.

and a mixture of the Subway diet and exercise.

Yep, it's a Jared frame. Although I don't know if he actually got any stronger?
