    Bebe's Long Travel H3 Build Thread - A Boy Howdy Story

    So this axle is an AAM-9.25? This has same diff cover as the Burban 2500 axle I got rid of. Its got 14 bolts on the cover but, the shape is different from the traditional 14 bolt that everyone is familiar with. I always wondered what it was called.

    On Pages 44 and 45 of the AAM Catalog (2013) the "AAM 925 14 Bolt w/Electric Locking Differential" is specific to the H2. While the cover might look the same on the "Burb" one you tossed, they are different. The H2 is wider, and at the time had Exciter Rings (tone rings) and came with a locking differential. (2003 - 2009).

    Axle shafts are also different and thicker/ taper different (up to the same splines obviously). Surprisingly there was alot of thought that went into the H2 14 bolt semi float

    We took the Bebemonster on her first trip rock crawling along with the Pups

    My faith has been restored! The Cooper 40's have a much stiffer sidewall providing far less sidewall roll than the 38" BFG's I had on her previously.

    Along with the new shoes came some new Hutchinson's. The 14 bolt H2 rear end is wider, just enough to ask the rear suspension to work better, the 6.0 needs zero acceleration to crawl, didn't need to BTM once!

    Wow is all I can say. Can't wait for the Forests to open back up so i can take her out again

    Sweet - You guys always beat me to my next idea! How was the H2 axle install? ABS tone rings work fine?

    Yes they were fine! Brakes - we had to go back to the OEM H3 equipment. The dual piston calipers made the the master cylinder malfunction. Too much pressure.

    Bummer, I may or may not need to replace the brake system in my truck anyway. I was getting a low pressure / voltage code. But that project will come around after the engine is in.

    For my clarity
    H2 rear axle with H3 rear calipers is the set up?
