    Sorry Rick, but 4.3 exists, 43/10 according to here:
    Precision Gear - Dana 60 Ring and Pinion Gear Sets

    4.27 must be one of those "jeep things" we don't understand (fortunately)

    Mcrover - 4.1 and 4.11 are both strong in a Sals!!! Even 7.17 will hold up to 44's!!!

    Well there yo go

    It was actually a Dana thing as Ford, IH, etc also used the 4.27:1 ratio. I think they were 47/11.

    I assume that is US$? A D60 4.10 is only $206.
    DANA 44, 28, 30, 35, 36, 50, 60, 61, 70, 70-2U, 70B, 70HD, 70U, 80 - DANA 60 AIR LOCKER, FULL SPOOL, R&P, YOKE, E LOCKER, OPEN, SEAL, SMALL PART, SPYDERS, POSI L/S, GIRDLE, DET LOCKER, TRUETRAC, ELECTRAC, FULL INST, SMALL INST, POWERTRAXX, AXLE SHAFT

    Rick - thanks for that - when I searched, all the info was related to jeeps - I found a lot of threads about people swapping them for 4.3s - maybe they are hard to come by these days.

    what would happen if you ran two different diff ratios at the same time?

    As long as the ratios are within 1% of each other iut won't make a difference.

    in a rover with a center diff and CDL (not a viscus) with the cdl unlocked youd eventually over heat the tcase.

    in a series nothing

    when you lock the center or engage 4x4 it would create huge wind up and break something or at least make the handling very strange.

    in something with the viscous center itd frag the viscous in very short order.

    In normal driving the rear wheels don't travel as far as the fronts (rears run on a smaller turning radius).

    So if the front diff was 4.1:1 and the rear was 4.11:1, then it won't make much difference.

    If the front was 4.11:1 and the rear was 4.1:1, then it will make a little difference - about the same as different tyre wear or rolling dia due to different load/pressure combinations.
