Hi,
New to forum, Looking at a 2016 3500 and was wondering what RPM it's turning at 70 MPH with 4:10 gears.
Thanks

What Trans ratio does the 68RFE have?

Dually or srw? Tire size is different and will make the numbers change.

My dually with 32" stock tires and 4.10 gears in 6th gear (Aisin/HO) is turning ~1911 rpm at 70 mph.
