Today we are doing something I've wanted to do for a while and that is compare different gear sets in a truck. on paper a higher gear set like the 3.73's in this ford F150 with the 5L coyote v8 should perform better then the standard 3.31 gears.

the reason is because 3.73 give the driveline a mechanical advantage for putting down more torque to the wheels then 3.31. this in tern gives the truck better acceleration and better towing performance when under load.

the downside of higher gearing is that the engine will have to rotate faster to maintain the same speed. this in turn can result in poor fuel economy. throughout out comparison today we go over fuel economy and we do see that indeed the higher 3.73 gears drink more fuel when towing on my towing loupe.

gearing is pretty simple but sometimes I find the number can be hard to grasp. at the end of the day if you want to tow more weight and have an easier towing experience putting in a higher gear like 3.73 gears will give your truck a mechanical advantage and will performance better.
