It comes with the same 9.5" rear end that the 6.0 gets, it comes that way in the Denali line and Caddy line as well.

im almost positive you can get 3.73s with the 6.2, if not its easy to swap gears, and as far as the centerconsole, ill trade you my jumpseat + cash for your center console

yeah it looks like if you order the max trailering pack on the SLT (LTZ) crew cab it comes with the 6.2L and 3.73 gears.

I would probably save some money and just get the 6.0 though. You have to remember that the 6 speed tranny has a 4.0 first gear which is why it usually comes with 3.42 gears.

I've checked the actual order guide and you can not get 3.73s w/ the 6.2 yet, I'm thinking that the 6.0 w/ a tune will be pretty close to the 6.2 when you figure in how under geared the 6.2 will be with 33" tires.

get the 6.0 it is a strong motor and 3.73's are a must! Plus it has been out longer than the 6.2 so i am sure there is more performance parts and add ons for it. let me know how the 33's fit and what you do to fit them cuz i am due for some knew tires pretty soon and i would like to squeeze some 33's under my ride.

I'll be doing the truxxx kit with a rear leaf spring instead of blocks (blocks cause too much axle warp). I'll have the local spring shop slid in a extra leaf or two (maybe enough to take the standard block out too.

6.0 and 6.2 use the same heads and intake, I believe that the 6.2 is just a punched out version of the 6.0 w/o active fuel mgt.

VMax

exact same heads, just a different bore the 6.2 has a larger bore. and you can probably squeeze more out of a tune in a 6.0 vs. a 6.2 I gained 65 hp and 73 lbs on a DYNO with a MTI tune. and Wheatleys tune was even better. I dont think those numbers can come out of a stock denali but i could be wrong. I just havnt heard of that
