ya just depends on the year of NNBS.
07-08 = 6.0 (L76) /4l70e / 3.73s or 4.10s
09 = 6.0 (L76) /6L80e / 3.73s
09+ = 6.2 (L92) / 6L80e / 3.73s

All include the 14 bolt, rear disc brakes as well an engine oil cooler

All 6.2s include the cooling package, 6-speed, and the 14-bolt; the NHT tacks on 3.73 gears and 300-pound-higher-rated rear suspension.

I love my NHT. I'd honestly rather have the Autotrac case over the fulltime AWD, as it gives you more options on what you want to do. Burnouts, easy dyno testing, launch in 4HI then cruise home in 2wd or Auto, lift a bit on offroad tires or slam it on street wheels, whatever. The Denali is sweet, but I'm really glad I went the route I went. Drive as many different trucks as you can.

Edited your post, you had it mostly correct. 09 was a wierd year you could get the L76 or the L92 depending on what point of the year you bought your truck. The L76 trucks had the option of 3.73s or 4.10s with the 4L70e trans. Mine has 3.73s but it has nav/dvd/sunroof which was more important to me

Or configuration of truck as well for 2009. You could not get the 6.2 in anything other than a crew cab whereas the the 6.0 liter was either or.

Again, thank you guys so much. I think I agree that I would prefer the NHT vs Denali. Another one for you, what trims could you get the NHT: LT LTZ, or SLE SLT I'm guessing.

Depends on which NHT you want. The 6.2's with it in 2009 were only available in crew cabs and only loaded ones (SLT/LTZ). Then in 2010 to present you can get either an extended or crew, 2 or 4 wheel NHT 6.2 in either LT/LTZ or SLE/SLT. The 6.0 liter trucks from 2007-2009 are the same deal as 2010 and newer 6.2's.......

I have a 2011 Ext.Cab SB 4x4 NHT Silverado and I love every minute I am in the drivers seat! I average around 15 mpg combined which is pretty awesome! I would go for the the NHT over the Denali because of selectable four wheel drive but they are both awesome trucks!
