You should probably start by figuring out what gears you have. I'd be surprised if you don't already have 4.10s. That being said I started with 3.58s and went to 4.56s when I traded up to 33s. I have no tach but my gas mileage came back to close what it was before I had 33s

 

You have a V6 which comes with 3.73 gears. I've spent about a year researching the gear ratio to go to with 33" tires that will put me back in line with stock.

4.10 is the answer. At 70 MPH with a stock truck, RPM is at 2100. With 33" tires and 4.10 gears, RPM is at 2100.

I'm actually ordering my new diffs next week (you have to do your front and rear diffs being a 4x4) from East Coast Gear Supply as they can build and ship them to me with a 5 year warranty and I ship my old ones back to them for a core charge. Easy swap and done.

Feel free to shoot me a PM if you want more info.
