Thanks guys, this is the kind of information I'm looking for. Another testament to how good this site is! Jake, thanks for the link, this is something to seriously think about. One way or the other, my truck will go faster, LOL. This weekend I will look for numbers on the rear axle and look into the gear ratio. This weekend I'm spending most of my time working on the truck anyway. The front bumper is coming off, (I'm building one), and I'm going to start sanding off the paint in prep. for a new paint job. I may even remove all of the bed wood. (All this after I finish stacking cord wood, winter is coming fast....)
