    I recently bought a set of new aluminum conmet uni mount hubs that fit my 46k rears. At $17.50 for the 4 I had to bring them home. I have seen lots of aluminum hubs on lighter spec otr stuff but will they hold together for the kind of abuse that heavy haul can give? Conmet says there rated for 23k axles
    Any experience?

    Never had a problem with them myself. My trucks run 37,400 to 39,600 on the drives depending where they are, and they’re out in the bush or on industrial roads at those weights on the regular.

    They would not be rated at 40k if they would not be suited for that.

    All you see down here is aluminum hubs with all applications. Been like that for 50 years since the SQ100 days. Unless you got spokes.

    Probably 30 pounds roughly, per hub

    It should be no more than fat, greasy driver vs skinny, slim :D

    Agree but there’s a difference between engineering and reality
    Honestly I am more worried about breaking the drive flange studs out than them not holding the weight

    When you’re already a skinny driver you gotta go after something else lol
    I really don’t care about the weight
    Honestly would have used iron hubs but these were to cheap

    To cut the weight you can always run on half worn tires, half a tank of fuel, take everything out of the cab but driver's sit, put on lighter mud flaps, quarter container of windshield washer fluid, something else to cut?... :D

    PS: I wouldn't worry about them being aluminum, as long as they are rated at the weight you are interested in. Main thing is to have good lubricant and break chambers, so bearings would not get hot and break shoe would not lock.
