Either of those gears will let you spin the tires... in OD while you hit your max speed of 45MPH. Ok, I didn't actually do the math but those gears would be right for a 40"+ tire. 35" with 4.10 is about as close as you can get to 3.73 with 31" tires. However, that is a vary minor step in gear sizes. 4.30 is the next step from 4.10 but you would be around 22-2300 RPM at 70MPH. Going to 4.10 or 4.30 will help if your towing and will help your in town MPG slightly. If your not towing heavy, I would put the money towards performance mods, changing gears in two axles (if your 4x4) is rather expensive.

Also if you want to get better gas mileage, consider swapping that gas motor for a diesel.

I have a either 5.10 or 5.33 in my axles(as im told by the 4x4 shop) but i can still drop my clutch and spin my big arse 44" boggers so id imagine youd be able to with 4:10s thats just my 2 cents so dont quote me

i have a tuner in the computer the max energy the only thing i set in it was for it to shift harder, its a V10 i dont know how i should set it to get better gas mileage. & on xtreme 4x4 they put 5:13's in the chey 1 ton with 35" tires & they go on highway & tow with it to so i dont know.& as for put a diesel in it i plan on it when the V10 dies im going to put a 24V cummins in it with the 6.0L tranny

The V10 is your biggest issue. 5.13 would tow great but you would be running really high RPM on the highway. They would also be a good choice for crawling at low speeds. If you have any good junkyards, you could look for a 4.10 rear axle and swap it out. If you like the gears, swap the front too, just don't use 4x4 till both match. The advantage of doing the axle swap is you could sell your old axle and recoup most of the cost.
