    <font color=blue>My truck originaly came with 3.07s and 31s, now it has 4.10s and 36s. I dont know how many teeth my speedo gear has, but how much correction does it need? Thanks!</font color=blue>

    The best way to tell is to drive next to someone whose speedo you trust, and when you are going 55 on yours, see what it says on theirs. I think every mph is another tooth you need to add.
