    I heard you could bore a D44 .060 over and it will be stronger than a D60. Is this true?

    You never want to bore any axle past .040, after that you are asking for trouble... /forums/images/graemlins/rolleyes.gif

    I never heard of that.... I think once you get past .040 you are going to have bigger issues. What about fluid leaking out because of the extra space in there now...

    I will use some JBWeld to stop the leak.

    I know I will get more flex cuz of the thinner axle tubes but how much weight will I save?

    You don't have the facts exactly right.... yes, and overbore of .060" CAN allow you to make the additional mods to achieve D60 strength (larger bearings, bigger diameter axelshafts, etc) but the strength will only be EQUAL to a D60.....not better.

    This was covered extensively in a post on another site. Now that someone has figured out the proper fixturing for the line boring process.....the axletubes can now be cut for the stronger internal parts. The beauty of the mod is the clearance at the pumpkin is significantly better than an actual D60.

    Costwise....it's really a good move for most people with a D44 front end. You can get all of the machine work, and updated parts for around $450. /forums/images/graemlins/thumb.gif

    It's still considered a pretty innovative and "new" mod, so don't expect too many people to have the details on it.... but I am willing to bet you'll be reading about this one for a long time.

    That's 2 Dana 60's welded inside each other with the ring and pinion from a Dana 15. Strong as hell!

    I've heard rumor that someone is coming out with a 40 spline outer just for this particular mod. This will make one heck of an axle /forums/images/graemlins/thumb.gif

    This doesnt only apply to D44's though. If you bore a 10B .030 over, you get a 13 bolt. If you bore it .035 over, you get a 14 bolt, and if you bore it .020 over you get a 12 bolt. Thats why I bored mine .035 over.

    Thats cool, so by going .035 over you can have a real 14B and it will look like a 10B. Talk about a sleeper axle setup /forums/images/graemlins/thumb.gif

    Yes this applies to front axles as well. we have all heard the rumors of the elusive 12b front and even less talked about the 14b front.
    You don't hear a whole lot about the 13b, but don't let this fool you. It has all the advantages of the 12b and the 14b. In the right hands these axles will tackle any terrain you need them to. I am currently running a 13BFF in the rear of my K5. My front 10b is getting prepped to be bored to a Dana 60 hopefully.
