Make Rear 1st
Toyota 4.30 14.32
Ford 3.31 13.80
Ford 3.55 14.80
Ford 3.73 15.55
Chevy 3.08 12.41
Chevy 3.42 13.78
Ram 3.55 16.73
Ram 3.92 18.48
The Chevy seems like it definitely ought to have the optional gears.
The Ram is for the 8-speed; the 6-speed definitely needs them but it appears the 8-speed compensates sufficiently, especially since the 2nd gear drop is much less than the others.
The Ford 3.5 only comes with 3.31; does the turbo give it enough torque so it doesn't really need the 3.55s?
Thanks.
I was just on another forum and the 2016 towing spec shows the same towing capacity of the 3.55 as the 3.31.
