    What kind of lift do you have under that??

    I don't think you'll find an electronic locker....ARB Air Locker or a Detriot TruTrak...but that's about it I think.

    Not sure what ratio to tell you to go to...but the tire calculator on the site (in the menu bar in the Wheels and Tires forum) is pretty helpful...

    gearing should be fine for moderate off-roading.

    so the larger the gear ratio the lower the gearing is right?

    Thats correct. The Higher numerically the lower the gearing. You most likely have 4.10 gears, I would stick with those.

    What is your stock tire?

    245 what? I'll need all three numbers. How about give me the stock size ???/??/?? then the tires you are running now, and the size you will run in the future.

    you can gear it down to 4.56 and be close to stock power to the ground. But with the added weight youll get less mileage and less acceleration

    he said stock 245s...245/75-16= 30.5"x 9.5" x 16"
    now he has 265/75-16s= 32"x 10.5"x16"
    He wants 305/70-26= 33"x12" x16"

    If you go with a narrower tire like 255/85-16 you get a 33" tire thats 10" wide= alot less trimming. Also, 12" wide tires require 9" wide rims.

    Ok so your stock tire was 30.4" tall and your gear was 4.10
    On your truck now is a 31.6" tall tire and your gear is 3.94
    You want a 32.8" tall tire, your gear will be 3.80

    I have some 33" tall tires with stock 3.73 gears. Seeing as my tires are taller than stock I have less gear than that something like 3.50 or so I'm guessing becasuse I don't want to do the math. I think your stock gears should be ok. Thats my $.02

    Oh and I think the 305's would be too wide, and heavy.

    Oh yeah but don't count that little guy out. I wheel with jeeps that are making the same if not less hp and tq than you and they are doing just fine for the avid wheeler. These are also daily driven vehicles. I've been drinking and can't recall the specifics right now which is why I asked you to post your tire sizes completely, because its a jumble right now. Back to my point though, I believe you are making enough torque to not have issues with your take offs. You'll notice it but I don't think it'll be that bad, I certainly don't think it will cost you any mpg. With the exceptions of the weight of the tires. I would look for something skinnier. Just my opinion, I would also think there would be a bit of rubbing on your UCAs with those tires. You can play with the back spacing but only so much.

    with 33" tires 4.11 (stock) would work but give you no power. 4.56 would give you the equivelant power of stock gearing with stock tire. 4.88 will give increased power but kill highway driving as you will winde it out while cruising...like driving in 4th gear at 65 mph

    4.56s will be the way to go. If your really looking for some extra gear you could go with the 88s. You need to keep in mind that your tire isn't just tall it is wide which causes two things, one being rolling resistance and the other being weight, and lots of it. With the lack of power the 2.7 puts out, you would be foolish to not go with at least a 4.56.
