    LSD centre

    Is it correct that there are two different centres: one is for something like 2.93-3.25:1 and 3:46 and shorter and the crown wheels are not interchangeable?


    I have a pair of LSD centres. At least one of which is supposed to be for the taller ratios. How can I tell the difference which is which or between them?

    I used a 3.73 lsd unit in a 3.25 diff. I know there are 2 different carriers but they don't change between these to ratios.

      A simpler question for the LSD gurus. Is this a 2.93-3.07 or 3.15-4.45?

        Im not sure how you can tell from just looking at the centre. But i think it's 2.78-3.15, it has to be offset slightly, so spacers/shims are different thicknesses too.
