    This just popped up so I’m sharing. Read the documents and make your own mind up . Unfortunately these have been sold as forged when they are not.
    Just a heads up......

    Yeah I dunno about that one, properly welded shouldn’t be an issue as that’s how they are designed to be used. ( ie not by a twit)

    It appears Speedway Motors have now changed the wording on their web site from Forged Steel to Cast Iron.
    This is an issue more people need to be made aware of and the potential for serious failure.
    Torana, how about adding WARNING to your header?

    Um , yeah maybe, I’ll Lookie and see if I can. I don’t think Speedway was aware they weren’t forged parts.
    Edit: That was easy

    You need to know the difference . . . .

    As we are aware of, forging and casting are two (2) very different manufacturing methods. Some may recall the cast Magnum axle failures a few years ago now.
    • Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape; and
    • Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.
    There are some qualified metallugists here on the HAMB, it would be interesting to hear their point of view on this subject.

    There has been a lot of discussion here on the topic in the past.
    As a trades instructor who teaches metallurgy to apprentices I know the difference between cast and forged parts.

    For my RPU I had originally bought a Magnum axle that I then drilled.
    In the process of drilling it was obvious that it was not steel, but rather a ductile iron casting.

    I decided not to use the axle as I didn’t have confidence in the material.

    I picked up a forged steel axle from So-Cal and the difference is drastic.
    A forged steel part is much stronger than the same part made from a ductile cast iron.

    It’s not rocket science :D

    Not sure if the guys from GMS hot rods in NZ are on here but I was just reading some stuff they posted about this. There could be others brand names that may be involved as well. Pete and Jakes are apparently doing the rightie (as I thought they might) @Greg Stokes

  12. Scary stuff. Just stick with Ford parts. They look better anyways

    I've always looked at the parting line(s) and if the part had a bell like sound when tapped. Is this a good way to quickly identify a forged vs cast part? Or, are they're better ways to evaluate a part before buying / using?

    stumpies pics show why casting should be left to a fisherman (person) not anything that your life depends on.that shit is very scary

  15. Thanks for the mention. Here in New Zealand GMS Hot Rods are an authorised dealer for Pete & Jakes and Superbell. These safety alerts came as a great surprise to me so I pressed LVVTA and also Jason at Pete & Jakes for more info because the safety alert information headlined Superbell but in fact goes for ALL cast spindles and perch bolts.

    It turns out that LVVTA knew of one incident with a Superbell and one with another brand but they didn’t expand on what happened as to what the incident or failure was.

    Then Jason said he wasn’t aware of ANY failures in 40 years of Superbell other than three incidents a very long time ago of dry wheel bearings causing the spindles to fail. He knew of no perch bolt failures either.

    As a dealer I just want to provide the end user with a solution to the problem which I’m working on with Pete & Jakes/Superbell at the moment.

    This deserves a bump as there must be a lot of these spindles out there.

    Yeah I recall the Magnum episode. Sort of too bad they cast safety items like that . Had heard of Superbell cast axles. :( Would never buy or use any of that.
