    Will a 3/4 ton dana 44 bolt right up in my '82 Blazer. I am thinking about going witha 3/4 44 and 12 bolt just to avoid the hasel and weight of a 14 bolt. thanks for the advice and help

    It will, but then you'll have 8 lug hubs up front and 6 lug hubs in the back. Do you want to carry two different spares? [​IMG]

    Yes, the 44 is pretty much a bolt on. The only thing that you may run into is that the 3/4 ton calipers may have a different bolt hold the brake line fitting to the caliper, but I think you can use your 10 bolt calipers..

    That is currently what I am runnigjn except 35's with a 6" Superlift Superride lift.

    The 1/2 ton dana 44s came with a 6 lug pattern. The only differance between a 1/2 ton 44 and a 3/4 ton is the lug pattern.

    FYI
    This is not always correct !
    There is more differences than the lug pattern.
    But its ok, we are having fun, and know what you mean !

    what are the differences , how much tougher are the 3/4 tonns than the half tons, could you swap rotors or would that be a lot of trouble, i figure that even a half ton 44 is better than my 10 bolt. thanks for the help what is the ring gear size on both 44's

    You really don't gain much by "upgrading" from a GM Corporate 10 bolt to a Dana 44. They're more alike than different. I'd only bother to swap in an 8-lug Dana 44 up front to match a 14-bolt full-floater rear end! [​IMG] A Dana 60 up front would be even better, but they cost WAY more than an 8-lug Dana 44. [​IMG]

    You may want to read the article on the front page of CK5 site called 6 lug to 8 lug conversion. I know it's not exactly what you want to do but there is some good info about parts and stuff.

    Stuck is a state of mind!

    A dana 44 is a dana 44. They use all the same parts, more or less. I made my 3/4 ton 10 bolt 6 lug just this afternoon since I don't have a set of 8 lug brake rotors yet. They're all the same, only a few parts are different. Neither is stronger than the other.

    "Neither is stronger than the other"

    I beg to differ. So 2 more lugs doesnt add strength? Larger bearings doesnt add strength? Thicker spindles arent stronger? Larger Hubs arent stronger? IF this is the case then I just wasted some good money not too long ago.

    No, it doesn't. You've still got the same ring and pinion, axleshafts, u-joints, etc. That's where the axle strength is. I don't know where you're from, but around here we never break wheel bearings, wheel studs, or spindles, and my friends run up to 44" tires on Dana 44s and 10 bolts.

    Not to flame you or anything, but it's my believe that axle strength comes from things other than how many studs of what size are holding your tires on or how big your wheel bearings are. If you use that thought process, a Dana 44 is stronger than a 10 bolt front axle because it has thicker axle tubes. I only have heard of one truck breaking an axle tube, and it was doing about 75 mph when it hit a huge bump and when it was all over there wasn't enough of the Bronco left to be worried about a front axle.

    Oh, and I forgot to mention, the axle that's under my truck right now came from an '82 K20. Since I didn't have any 8 lug brake rotors, I put the 6 lug parts on it. So, technically, it's a 3/4 ton axle, but it has 6 lug rotors, spindles, backing plates, and hubs. So is it stronger than the axle that was in my truck before that one, becuase it came from a 3/4 ton? Nope.

    If the 'second design' axle parts were used (77 on up), then the 1/2 and 3/4 ton bearings, spindles and internal lockout hubs are ALL THE SAME THING. There are no size differences between the two. The only difference is the diameter of the rotor and backing plates, and the 2 extra lug studs.

    84 K10: A d44 is stronger than a 10 bolt as it has slightly larger axleshafts and a higher spline count. Yes the ring diameter is the same, but you also mentioned the axletubes are bigger as well. Yes my thought process tells me that having larger bearings and more studs and larger hubs adds to the general strength of the axle, cause it does. It just doesnt help out the "known" breaking points that you must encounter. I wheel my D44 HARD on the rocks with a light foot and I have yet to break anything on my D44. So theres more to breaking things than just having weak parts.

    thatK30guy: I dont know if you noticed but my K5 is a 74, so I have the 1st design and I do have the bigger/stronger of the parts on my D44. Thank you for the info on when they changed the designs, I wish I had that when I wrote my article.
