    I mean it is a 8lug HD truck so why not put it in?

    It would get better mileage, More power, not to mention just be bad ass

    prob not but it can be easily done, fromthe factory.

    shit this last month there was a h3 from [SIZE=-1]Bulley Dog with a 6.6 dura

    doesn't it use a 10bolt rear? That needs to go.

    New 4.5L Duramax will be offered in the H2 for 2008.

    You can get the 6.6 swapped in after market. IIRC there's a place in Kansas that does it.

    are you serious? Thats what my fuckin S10 has... Granted my 10 bolt has stood up to 35s and a detroit with 4.56s, but still... I dont see how a 10 bolt could handle a huge ass H2.

    Yes, the S10, H3, Silverado 1500, H2 -- all have the GM 10-bolt.

    there are several sizes of 10-bolts, 7.5", 7.625", 8.5".

    The S10 is a 7.625", I think.
    The H2 is a 8.5".

    Still -- the GM 10-bolt is NOT appropriate for a 6.6DMax. Even the gasser 2500HD trucks get a beefier axle.


    MANY people have cooked the 10-bolts in their half-ton silverados. It's not a great axle, imo.

    right it needs the 14 bolt if it had the 6.6

    my 10 bolt in my old z71 was plenty tough. took 33's and hard ass beating so lets not call it a peice of trash...

    now, whether it is duramax capable... is yet to be seen. when they come out i will surely be getting a 1/2 ton pickup with the duramax and plan on testing whatever rear axle happens to be in it.

    No, I think trash is a good way to describe it. Don't get too butt-hurt, I've owned 3 vehicles with 10-bolts. But that doesn't mean that I have to bow-down to every part of the component.

    "agree to disagree" [/anchorman]

    no butt-hurting at all. i have heard many horror stories from guys with 10 bolts. i guess i got lucky with mine. I do agree under a big H2 with a Dmax the 10 bolt would almost certainly fail... but for the daily driver who is typically very light on their car/truck, i think the 10 bolt can work out is all I am really saying. I honestly dont know how mine lasted as long as it did.

    word i was waiting on somebody to say it.. the h2 is a 3/4 truck pretty much so it would share the 9.5" 14 bolt

    Where are all these bolts, again?
     
  15. They are the bolts that affix the ring gear to the carrier.

    On a GM axle you count the number of bolts on the dif cover. If there are 10, its a 10 bolt... 14 its a 14 bolt... pretty simple.

    See, it sounded like you were talking about hubs for a minute, but when the numbers got up into the teens I knew it couldn't be that.

    What's the significance of having a ton of bolts on the differential cover? It's not like it's a structural component.

    the cover is not so much, but the bigger the cover, the more bolts it will have, and the bigger everything is inside. Given the marerials are the same, a bigger component is beefier, and thus stronger.
     
  19. My guess is that since the cover is usually just a piece of stamped metal they need that many bolts because as the cover gets larger it lacks the rigidity to seal reliably with fewer bolts. They may have put 10 bolts on the cover of a 10 bolt rear and so on for easy identification, but the "10" in 10 bolt has nothing to do with the number of bolts on the cover.

    Sounds plausible.

    They should do what VW does, instead: seal it with a combination of rubber and liquid silicone, and use a combination of clamps, zipties, and stretch bolts to ensure perfect distribution of force along the seal circumference. Then they should devise a wickedly-complex two-zone lubrication system that lubes the outer bearings with thinner oil, and the differential and thrust bearings with thicker oil, in order to achieve .0001% greater energy efficiency.

    Buncha cavemen in this forum, I swear.

    Now is probably not the best time to mention that my car's differential actually has the two-zone lube system described above.

    There's engineering, and there's overengineering. This is just silly.
