Friend of mine had a 5.0 Explorer as a daily driver. Realtor. Lots of driving all over town. Originally came with 3.73 gears with the tow package. He swapped them out for 4.30 gears and loved it. No loss in economy in daily driving. When he towed his race car, it towed better. Quicker ETs at the drag strip. Only down side was the ECM wasn't as happy and would short shift at the drag strip. This was also the very early days of anyone doing any tuning on these ECMs as well. And that was all with stock tires. 29" or so.
