Do all 6.2L come factory with 3.42 gears?

[ugaDAWGS09]

I cant find the information online but was wondering how the 6.2 with the 10 speed and 3.42 would run with 35 inch tires vs the 5.3 3.23 gears and 8 speed ? I dont really do any heavy towing but how would it be with daily driving, mpg, etc.? Are the 3.42 standard with the 6.2 engine?

3.23 is standard. The 10-speed is the biggest difference...

Both engine/ transmission combos have 3.23 standard but can be had with 3.42 with the max trailering package (except on the Denali and High Country).

High Country can get NHT, just not Denali.

Yeah, sorry, my comment was unclear.  I was playing around on Build and Price and it  seems that if you want NHT on a High Country you have to get the 6.2; it's not available with the 5.3.  I'm not sure if that's just a quirk of the build and price program itself or a Canadian thing or what.

Same for US.  NHT on High Country requires the 6.2.  LT and LTZ give you the option of the 5.3 or 6.2 on NHT.  All NHT get 3.42 gears, 3.23 is standard w/o NHT.
