    How can I find out what rear diff gear ratio I have? I just bought the truck and the previous owner didn't know.

    Thanks:D

    The axle code for your rig can be found on the manufacture's sticker located on the driver's side door jamb as follows:
    First digit:
    • A = 7.5" ring gear
    • B = 8" ring gear
    Next two digits:
    • 01 = 3:42
    • 02 = 3:58
    • 03 = 4:10
    • 04 = 4:56
    • 05 = 3:15
    • 06 = 3:91
    • 07 = 4.30
    Last digit:
    • A = 2 Pinion, Open
    • B = 4 Pinion, Open
    • C = 2 Pinion OEM Limited Slip

    If your looking at the sticker is it the bottom right number / letter code. And if so mine is B03A. What is the difference between 2 pinion open and 4 pinion open?

    Thanks Chris4X4 for the fast reply :D

    yeah. It should only be 4 digits. I.e, B07a or the like.

    So my truck is also B06A, 8inch diff, 2 pinion 3.91 gears. I am running 31 inch tires and will eventually go to 33 inch tires, I should go to 4.10 gears to keep it "Normal" on and off road?

    And the front diff is the same ratio. They are a set, right? So I am looking at two sets of gears, one front and one rear. Come on economic stimulas package number two.......

    I would check into 4.30's. I was running them on my 2000 Tacoma with 32's and thought it was a good match.

    Ok, I've been lookin around at a bunch of conflicting articles...do you believe that my A04C is truly a 7.5" 4.56 with LSD? Some say all V6 with auto are the same.

    Only asking because I am about to order a 3rd from ECGS and really only want rear locker for now...so no regearing needed already having a 4.56 in the front would be hella convenient.

    Pretty sure no 2nd gen had 4.56 from factory. V6 Auto should be 3.73 I think.
