    Stock tire size is 265/75R16, so I would be dropping a little in height. Anycomments good or bad?

    I know it would affect my speedometer and so forth, but could I just get Allen to adjust my tune?

    They will work fine. Allen can adjust your speedo for you. He did mine when I put 4.10s and 20s on my truck.

    It will also have the effect of having a lower gear....your 3.73 is going work like a 3.85.

    A small amount of increased multiplication of your engines power. A very minor increase in rpm. Kind of the same effect of swapping gears from 3.90 to 4.10s.
