    What is actually stronger, a 10 bolt or a D44?

    Yeah I am pretty sure a D44 is stronger but don't know why cuz i still got a 10 bolt up front.

    Stuck? Isn't that a bird!

    From everything I have heard or been told there is not much of a difference between the two of them.

    Dana 44's have a slightly stronger housing, but are pretty much equal in every other aspect.

    I agree with others, I really haven't heard much difference between the twos. One + I have heard on the 10 bolt is a larger pinion over the 44.

    FYI Dana(Spicer) did not build the GM 10 Bolt. NEVER !
    Provide me with a sample of both, and I'll test them for ya.

    All things considered, in the end they are the same in strength and it would not be worth swapping one over the other (in terms of strength).

    Executioner, I'm missing something here, why write "FYI Dana(Spicer) did not build the GM 10 bolt. NEVER !" he stated that it was a <font color=red>GM</font color=red> 10 bolt while the other was a <font color=red>D</font color=red> (for Dana) 44. Did I miss something here?
    I can usually follow your logic (as some can't), but this one does intrique me.

    And to answer the original question. Both the 10 bolts and D44's have some advantages over one another, and disadvantages over one another. The 28 spline 10 is generally considered weaker than the D44, but the 30 spline 10 is thought (noticed I said thought) to be better than the D44. Either way the differences are pretty much insignificant, if one will break in a given situation, the other one would have too. As far as ring and pinion swaps, the 10 uses carrier shims on the outide of the bearings and the D44 uses them behind the bearings (may mean a little more pressing and unpressing), but other than that it's six of one, half dozen of the other.


    If you didn't build it yourself, how can you call it yours.......?

    To add to what the others have said, the D44 uses slightly larger carrier bearings.

    Generally the swap isn't worth it unless you are getting better gears or something like that in the D44..

    Dude, two things...first off I thought you were in AZ? Secondly are you offering to show me that legendary 12 bolt front axle?

    As long as we're discussing facts how exactly would I know that your front end was a factory offering and not some piece bodgered up by a previous owner. With a machine shop at my disposal I could show you a 14 bolt front end...

    Regardless...I'll pm you from Talldogs place in San Diego.

    I'm pretty sure we'll be in San Diego on August 6th...
    If you're anywhere close I'd really like to see that front end.

    Hmm, to sort of sum up what others have said and what I believe to be true:
    10 bolts do have a larger pinion gear diameter, although the ring gear diameters are the same at 8.5''
    The 30 spline count of the Dana 44 is supposed to be a little stronger than the 28 of the ten bolt, which is basically meaningless because usually the u-joint breaks first anyways, esp if you upgrade the shafts.
    Dana 44's have a greater wall thickness in the tubing. I think this isn't really an improvement compared to the 10 bolt, because the tubes aren't the problem areas.
    And its been said before, they are basically equal. The only reason to swap one for another (which is pretty easy) is for some other reason than strength...gears, 8 lugs, etc.
