3.92 gears
My city mileage did go up about 2mpg when I swapped to the 4.10:1. The only highway driving that I have done is pulling a trailer and the mileage was okay(!). Probably better than the 3.55:1 would have been but I have no way of knowing. The RPMs are about 450 higher with the 4.10, 70mph = 2450rpm now.
