Rear axle ratios

Ford's 3.5 EB does come with the 3.55 optional rear end. Another key aspect to Ford's rear axle is the ability to electronically lock them. I've used it numerous times and not needed to engage the four wheel drive on soft terrain.

I drove an EB 3.5 today with the max tow package and noticed the differential lock switch; I forgot that a locking differential and 3.55 gears are part of that. I haven't driven one with the 3.31 gears. I've driven a 2.7 but don't remember if it had the 3.55 or 3.73 gears.
