    Thats what I sell my axles for. You are definitely getting a good deal here. Go ahead and get it before someone else does.

    Uhh...If you're going to 38's or larger later the Dana 44 will chuck parts just like a 10 bolt...just because its a 3/4 ton front end doesn't mean its any stronger than the 10 bolt its replacing, sad but true. For tires that large a Dana 60 is in order, and good luck finding one for cheap![​IMG]

    Nope, sorry. Both are 8.5" ring gears and use the same outers (to a point) The only thing that makes the 3/4 ton version different from the 1/2 ton version is the 8 bolt outers....

    Sorry, I gotta agree with Rene. Anything over 35" or 36" is getting into D60 country. Especially if you are making any decent power, geared low, and really using it for a 4WD. It is possible to run large tires on a beefed up D44 or C10, but it is money down the drain as far as I'm concerned. If you use it, it *will* break long before a D60. It's not a matter of if, but rather when.

    However, a blvd. queen would probably do fine with that setup, at least you would have the heavy brakes to stop that enormous rolling mass. Depends on what you want.

    Sorry Rene but I have to disagree with you on that the D44 isn't any stronger than the 10 bolt.
    Although the r&p are of the same size, the axleshaft diameter on the d44 is larger, and it also has a higher spline count (which adds strength).

    Dana 44 (8.5-in. 1.31 Axle Dia. 30 Spline)
    GM Corporate 10-bolt (8.5-in. 1.28 Axle Dia. 28 Spline)

    Now .03" isn't that much, but it does add strength nonetheless, and 2 splines is a big deal when it comes to axleshafts....

    I've ran 35's on my D44 for over 3 years now on 4+ rated trails and havent broke a thing. *knock on wood* Although I am light on the pedal by nature which prolly has A LOT to do with it. FYI, 3.73 gears, lockrite locker in the D44.

    Well I never said they were "identical". My point was they were'nt any stronger than their half ton counterparts....
    I wouldn't run "38's minimum" on either a 10 bolt or a Dana 44 without expecting parts to break.

    89 and up c10's have 30 spine axles. But the axle size is still 1.28".

    If you go dana 60 you with 38's you will loose major ground clearance. It will become an anchor and you'll get stuck a lot easier .
    If you go Dana 60 ideally you should go 44's.
    Dana 60 w/ 44's gives you about 15" clearance. Imagaine how much you'll loose with 38's

    A dana 44 with 38's could work depending on the tire you choose. If you go with pizza cutters- 38.5x11 boggers it could work.
    The tire is much lighter and put less stress.
    I've used that combo before and it has worked fine.

    GM started using 30-spline axles in the front 10-bolts around '89, but they are 1.31" diameter just like the 44 shafts.
    When comparing the 28-spline 1.28" 10-bolt axles to the 30-spline 44 axleshafts, I don't think the spline count and diameter really matter because of the tapered down section both of these front shafts have right before the splines go into the carrier. This is the point that will always break on the inner shaft. Now if this taper wasn't there, then the larger 30-spline shaft would have a definite advantage. I would be curious to get actual measurements of the diameter at this taper and compare the two.
