do I really have 3.42's???
 

glovebox doesnt say GT4....i was sure when i bought the truck that 3.73's came with the HD trailering or All Terrain Offroad package but i dont see the GT4 code there...that was one of the reasons i bought it. WTF :bang:

I see you have a BBtune.
Ask Justin whatit says.
Or list all the "G" codes. GU6 is 3.42s i believe?

yeah it says gu6

Z85 trailering hardware notwithstanding, GU6 = 3.42 :(

3.42's? No need to swap in different gears when you can just turbo the truck and be satisfied with the gears. :chug:

yup :cheers: Tellem CC05

Max trailer package trucks only have 3.73's. Being you are an All Terrain ( can't combine the All Terrain with the Max Trailer ) you have 3.42's regardless.

imo 3.42's is great with the 6 speed trans.... i love it..

I really wanted a body color All Terrain truck w/ 20's, but you couldn't get that with 3.73. The ONLY reason why I accepted 17" wheels was to get the gears.
