Maybe I'm missing something.
    Not sure where the 8000 ft-lb number comes from.

    Keep in mind that's 2600 ft-lbs at the input yoke - now multiply by 1.5 and you're looking at about 4000 ft-lb at the hub during a 100 hour durability test with no degradation in performance. We still have not found the ultimate torque limit yet.

    If you can get 4000 ft-lb at one wheel to hook on any surface then you have a hell of a tire or a massive corner weight.

    Cool. I love it when we get input right from the horses mouth. Welcome.

    The 8000 number is tossed around quite often. Might be from the Dana 60 bible on Pirates

    There are some claims about half way down, indicating nearly 9000ft/lbs for a stocker to nearly 15000ft lbs for an aftermarket upgrade.

    My little 4 cyl diesel makes 250 ft lbs peak and has about a 200:1 low range. I guess mechanically I could create 50,000 ft/lbs. In places like Moab it's pretty easy to put the rig on one wheel and being heavy as it is, broken axles are a fact of life. I just have spindly little Cruiser axles at the moment but even the guys with Dana 60s manage to break them with some regularity. I'm just sayin, 2600 doesn't seem like much. I'll look forward to seeing the that data on the ultimate breaking strength. I'm guessing it'll be much higher, and I'll be standing in line for a set. For $6500, these portals answer a lot of expensive questions. Of course, some kind of unconditional warranty would ease my concerns as well

    Paved roads are another example of needless government overspending.

    OK, I'll do some more homework on what breaks in a 60 and at what level.

    If it provides any more confidence, we ran an analysis case during the design phase we called "one wheel pushoff" - all vehicle torque through one wheel with the weight of the vehicle on the same wheel and the steering providing a substantial lateral load. We found a couple of minor places that were yielding that were fixed in the final design but no overall no major issues.

    Defenderbeam - we're having email issues so please accept my apologies if you have not had a response from us yet.

    If by "metric version" you mean the box is assembled with metric fasteners then our boxes are indeed metric. We design and build most everything we do now in metric. Case, cover, and knuckle on each box are held together with M12 flange head capscrews. Locknut on the rotating assembly is a standard 60mm part.

    Hope this clarifies your question.

    There is an article about the bolt on portals from axletech in the newest Petersen’s 4 wheel and off road magazine.
    “currently available for dana 60 and corporate 14 bolt axles, but will soon be made for various front and rear axles (some models may require welding), and a smaller and lighter version is coming eventually for half ton and smaller axles as well as IFS!”
    Check it out, they have pics of the instillation they did, also in the Montana road trip article they mention that portaltek is also working on a lighter version of their product.

    The C303 and Unimog404 portals are much diffrent than the ones axletech has. I believe the Axle Tchs are a 1 to 1 ratio.
