    how much of a PIA and $$$ is involved?
    i thought they make a thicker ring gear for these.
    or is it better to just find a 3-series carrier and change it out?

    I think the spacers will work with any gear set but you would just have to try it. It would be easier to get a 3 series carrier some gears and set it up once. It will make a noticeable performance change. Down side, lots more RPM on the highway.

    The 2.41 uses a 2 series differential and the 3.73 uses a 3 series. There are no thick gears for the 8.5 10 bolt. If you are going to use the 2 series then you will have to use a spacer, which I don't recommend.
