The aero on your Ranger is likely a nightmare. Before dropping $1000's on changing your gearing - which would almost certainly have a good result, no denying - you can get pretty good results with a few aero mods. If you don't go offroad much - and few people really do - you could do a lot with a simple air dam. If you're worried about it getting torn off by deep snow, make it one that's easy to remove and reinstall.

My truck has 3.73 gears and I am certain it would be happier on the highway with 3.55, maybe even 3.35. It just sounds buzzy. But I'm too cheap to do it.
