I would just look for a set of 4.56 geared one tons.

Real-life gearing input

Keep in mind when doing RPM calculations that as you get bigger and gnarlier tires, beadlocks, etc., your highway speed may actually reduce from balance and roundness issues. For 55MPH roads there may be no difference, but you probably won't tear up the freeway at 80MPH any more.
Thanks for all the input here guys- I am going to see what my next step is and go from there.
I think sometimes people have a tendency to suggest gears deeper than required on here.

If your gonna drop a thousand dollars, might as well make it worth your money and plan for the future
I kind of agree with Martin.
Having really deep gears sounds cool.
Then you find yourself too deep geared and winding it out on the freeway or at anything approaching freeway speeds. Even if you can "safely" hold 70mph you may not be comfortable with the faster rpm's and you can watch the fuel guage drop.
Not everyone's a rock crawler. Especially since he plans on driving it across multiple states to go wheeling. Me personally, not that I have a wheeler any more, but I like my stuff to be road friendly to some degree. Having really deep gearing is fine when you're on the trail but it sucks when you're going down the freeway at 60mph to get 2mpg better or listening to the engine drone at higher than normal rpm and worrying about the fuel bill.

Exactly.

Im glad I choose 5.38s with the 700r4...on the freeway trans stays in overdrive even in the hills unless you floor it...gear the truck for the freeway like I did, makes it nice to drive, I didnt want the 3rd gear hunt...
It really depends on what transmission you have, and when talking about the 700r4 you need low gears. You can put 5.13 axle gears in a truck with a 700r4 and on the highway in OD it is equivalent to 3.60 axle gears on a truck with no OD gear. Don't think anybody is going to say that 3.60 axle gears are too low on a truck with 35" or larger tires with an SM465, TH400, or some other non-OD trans. You also need to remember there is more than just the increased diameter of the tire to take into account. Larger tires are usually heavier, more aggressive tires have higher rolling resistance, and add in a lift kit that increase aero drag. Lower gears also help compensate for those items.

Anyone already considering 4.88s or 5.13s that hasnt figured in the fact that gas mileage will certainly be in the single or very low double digits had better get their brain checked because thats common sense.
I would agree with you only because those gears usually go side by side with lift kits and large aggressive tires. 5.13's with a 700r4 and 35's is lower RPM at 65 mph than my stock 2500HD and only about 100 rpm higher than crappy 3.08 gears with a TH350 or TH400 with stock tires.
