    If I were buying a Tremor; it would be the new 7.3 gas with 4.30 gears. I wouldn’t care about fuel economy; give me as much power to the ground as possible.

    To help you explain it....

    The lower the number, the faster the car will go with the same number of engine revolutions. The higher the number the better the car will accelerate, but at the expense of high speed cruising/fuel economy. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa.

    4.30 would be considered LOW gears. Now a days you wont find much under 3.23 which would be consider HIGH. The Ford offerings right now off the top of my head are 3.31 - 3.55 - 3.73 - 4.10 - 4.30

    To OP - just get a diesel with 1050ft/lbs and forget about the math.... :)

    "High" and "Low" by themselves are are qualitative descriptors.

    Ford seems to be more interested in quantitative descriptors, so they use actual numbers in their specification of the gear ratios in their axles and transmissions. If you say "numerically higher" or "numerically lower", there is no ambiguity whatsoever.

    I agree. I would always select the highest rear end ratio possible if I was ordering a new truck.
