Which gears.....

Ok I know this has been covered a few times and I searched, but I didnt find what I was looking for. I have a 99 with an AX15 with stock 3.07's with 31's. I am eventually going to be going to 32's and that will be the max. I know a lof of you will be saying oh you will go bigger but the truth is, this rig will be used for expeditions and such so bigger tires arent really needed. Just a winch and a few other goodies with the 32's will be perfect. Ok so here is my question...To retain better gas mileage and have the power I need, would you go with 4.10's or 4.56's with the 32's and a 5 speed???

4.10s would be about right, i dont know if they have them for the 8.25, but sounds like some 4.27s would be perfect.

You can get 4.10's for the 8.25 about anywhere, Randy's Ring and Pinion has them.

If you are going to be running the highway a lot you could get by with 3.73.
