4.56's will absolutely kill your mpg. I have 3.92's and pull 1800 rpm at 65mph. Average 20mpg on the highway. They also give me plenty out of the hole power. I don't race my truck though.

If you plan on lifting and putting on bigger tires go with the 4.56, if you plan on keeping roughly the same tire diameter got with the 4.11's

OK, are you towing or racing 1/4 mile??

3:21 for best gas mileage
3:55 for the every day Joe average
3:92 for the guy that tows a boat or trailer on weekends
4:11 for guys that pull really heavy stuff on weekends & take their truck to the drag strip occasionally
4:56 if your a farmer & OCCASIONALLY PULL STUMPS & like to show off at the 1/8 mile drag strip

You can pretty much count on your mileage going in the toilet with the 4.56 gears. If you're not going to do bigger tires, you should go 3.92. You'll get more grunt off the line and still maintain 15 mpg or so, plus you can easliy reprogram the PCM with the correct ratio and tire size so your speedo will stay accurate.

I have thought about gears a lot lately myself.

My '98 Ram 318 has 3.55 gears and 285x75x16 and I have wondered if I would be better off with 410's or 456 or just leaving it alone.

Do you do much towing or heavy hauling?

If you're happy with the way the truck performs as is, there's really no need to change. A swap to the 4.56 gears will probably be way more than you want, so if you decide to change, I'd recommend the 3.92 or 4.10 gears.
