Make sure that the cost of a gear change makes financial sense. Your mileage might increase by 1 or 2 mpgs but it's going to cost ~$500 an axle to have new gears put in. You have to do a lot of driving to make up for the cost.

I'm sorry but you simply haven't provided enough information about your truck to get productive suggestions. What axle gearing is in it now? What transmission does it have? Is it 2wd or 4wd? How big are the tires? How fast do you drive?

I wouldn't mind doing a whole axle swap but I have had better luck with finding new gears than I have with finding whole axles plus I will need to swap out the front diff as well so right now I am looking ring and pinion sets.

with a 4 wheel drive you are looking at around $1000 for a gear swap.
get rid of the big tires and go back to stock size, and you should see a noticeable increase in fuel mileage.

Some peeps refer to these F250's as a Light Duty, but FoMoCo did not.

Although I appreciate that you want more info the amount of replies suggests that I have provided enough information, but since you ask - It is a 4x4 302 and the 4 speed that, I am told, is a Borg Warner. Also, the tires are big and that is all I can tell you but it came with 5 stock sized tires on rims that I intend to put back on the vehicle and sell the larger off-road application tires

And if you dont even know what axle or ratio you have changing gears is WAY over your head

all this info below is your issue but like mentioned you need to figure out what gears you currently have.

Also - This may be wrong but I found an identification guide that suggests I have the Sterling 10.25. The misunderstanding comes from the prior owner telling me I had the Dana 60. Still interested in finding out what the ratio is.

you should have a tag on either the front or rear diff, might also show if you look on the door jam. this would all be mute though if the previous owner changed the gears at some point also. may have to do the tire rotation and count how many times the drive shaft rotates.
