Gear ratio question

[tatheho]

When I look my vin number up, it says front and rear gear ratio 4.10,3.73 4.10 max 3.73 min so? Im confused a little

Says it's either 3.73 or 4.10.

I didn't know they used those gears on the 2015-2020 trucks?

I thought 3:08 without max towing and 3:42 with max towing.

Those were options for that truck and your RPO code tells you what it actually is.

In your glovebox, should be an SPID sticker with a buttload of 3 character codes.
It has one of these, but not the other.
GT4 is 3.73.
GT5 is 4.10.
Let us know what you have ... or not ...
