Which axle ratio is it really?

[Bhall5482]

I have a 2017 2500 Ram and have downloaded the build sheet and window sheet and still cannot determine which rear end I have on it. The sheet shows 3.73 as standard and the 4.10 optional. It does have the heavy duty tow added but i bought it second owner and not sure about it. It has most of the optional equipment it shows but not all so how can I tell which one it really has? Any words? My VIN is 3C6-UR4DJ9GG-138702 if that helps

You should have the 4.10 in your truck.

If your build sheet says 4.10, what's the distrust?

Both of those will list standard equipment first. Then they will list optional equipment.
The optional equipment is what was added to your vehicle. So if the 4:10 is on that list you can rest assured that's what the truck has.
