C7 axle ratio
Recently purchased a 2017 C7.
I bought a build sheet and it came in today and says the axle GXB is 2.41 which I assumed is standard on a 1LT with A8.
I bought a laminated window sticker and on the windows sticker and it shows rear axle ration 3.42
Which is it?

The window sticker shows the standard equipment which would be an M7 with 3.42.
The optional A8 overrides the standard equipment and has the axle ratio shown on the build sheet.

I will give you an educated guess. The M7 Trans is the standard(no charge) trans that comes in a C7 & that comes with the 3:42 axle ratio. When the optional Auto trans is ordered, then the 2:41 axle ratio comes with the auto trans (A8).
Plus when the C7 is a Z51/GS A8, the axle ratio is 2.73.
