Multiple "G" numbers in the glove box
I looked in my glove box of my 07 Silverado LT 1500 4wd and among all those letter with numbers i found a G4/3.73 gear ratio and next to that a G80/heavy duty
So do i have a heavy duty rear end with a G4 gear ratio?
Also my vin number has a Z1 in it. Does that make my 07 Silverado a Z1 Silverado?
There are no badges on my truck. It was repainted when i bought it.
