My 2017 EB has a 3:31 rear end.

Must be a 4x4. The 3.5 EB with the 3.31 is only available with the 4x4. The 3.31 ten speed has the same first gear ratio as the old 3.73 six speed. Of course, the ten speed is only available with the 3.5 EB in 2017. I prefer the 4x2 Supercrew which is not available with the 3.31. It is offered with only the 3.15 and the 3.55.
