    I'm looking into buying a D60 to put under the back of my 79 K10. I realize that there were different versions of this axle and was wondering if there are any I should stay away from or look for. Thanks for any help.

    Re: RR D60 info

    I'd stay away from a D61, this is a variation of the D60. The D61 housing is designed for the very high ratios, such as 3.07, 3.23, etc. (the pinion is offset to allow for the large pinion on the high ratios). I know this housing is limited to a 4.10 Spicer gear but I don't know if any aftermarket companies make lower gears for it.

    These are most common in Ford vans. There easy to catch though, the diff webbing has "61" cast into it so if you see one - RUN! /forums/images/icons/grin.gif

    Re: RR D60 info

    a RR60 for the rear is a custom built axle using a rare ford front 60 housing or an $$$ aftermarket housing.
    I doubt you will have to worry about a RR61.
    IIRC ford didnt use carrier splits so any one will work.
    this is usually a Heep mod and I dont see the point in a fullsize.

    Re: RR D60 info

    By RR60 are you referring to a regular rear Dana 60 FF axle? Rear Dana 60 FF's are pretty common in non-GM brand vehicles. Am I having a thick headed moment?

    Why not use a 14 bolt FF? It will go in so much easier and its stronger anyway. The only advantage of the Dana would be that you can get lower gears for it.

    RR usually means Reverse Rotation

    RR=rear Sorry for the confusion. I mainly wanna go with a D60 for weight purposes and the larger selection of lockers. It will be plenty strong for my use. I'm not totally stuck on the idea of a D60 but right now it's what I'm thinking about, I may end up using a 14 blt anyway. Thanks.

    the 60 is a nice axle but has smaller shafts then a 14 or 70 and has many variations.
    you would have to do your homework and pull a shaft on a prospective dif to know what you are getting inside
