As when chroming sometimes the metal will get Hydrogen Embrittlement & I would bet that is what happened to the axle.....joe


Damn Bob your quick & it seems we were thinking about the same thing.....

And Magnum, where I bought mine.

Agreed, the only axles i've ever seen break was because of an accident or been badly fitted.

Axles mounted like that with split wishbones need some rubber ends on the links to allow for a little flex/bind issues--the use of hard ends/heims will put the axle in a very high stress every time it moves in any direction

Yup i forgot them. Its gets me when people jump on the "bash speedway wagon" Lots of companys sell stuff made in china, You just need to do your homework when buying stuff.

Well after you read so many posts about the crap they have gotten from Speedway, it make you wonder where there stuff comes from and how it's made. As far as buying that Chinese JUNK, you can buy all you want(if that's what you want to do), because until they prove to me & lots of others that they can & will make a quality part. I'd rather buy stuff from Japan or Mexico then China if no USA or other QUALITY part is available.

Also did anyone else notice how funky the inside of the kingpin area is in the 1st pic.
This tells me it was a poor casting w/lots of air bubbles in it...joe

I'm not bashing Speedway - I do purchase a fair amount of "stuff" from them and have never had a POS yet, even the Chinese crap seems better then some from Taiwan or Indonesia. I just don't use any of those pieces in a stressed or shear situation.

The chroming by a shop that doesn't have a clue on H2 embrittlement would upset me - and I would probably chalk it up to experience (like a pair of $400 each wheels that don't fit over my rear Wilwoods) and use that axle for a door stop.

Dave i see Speedway getting bashed all over but my point is that a lot of the stuff is actually bought in from other companies, for instance the halogen conversion kits are from Vintique and are real garbage but people blame Speedway.
I've had hordes of parts from Speedway over the years and never had any problems but as with any company not everything they sell is great quality, you just have to do your homework.

I haven't seen much bashing of Speedway on this side of the Big Pond and since NSRA-UK refuses to let me post for yet unexplained reasons, I don't bother with that site any longer so don't see their complaints. I get both Speedway catalogs, street rod as well as the racing and purchase from each. I do have to say that for most items mechanical, I do prefer Summit if for no other reasons but much faster delivery and better customer service.

Now, back to axles - the Magnum has at least a good website, Super Bell - nada. Then of course, there's Chassis Engineering. I would make a call and see if indeed which, if any were made somewhere besides the Far East. I would also make sure that it was a forged steel rather then a cast piece. Aluminum - pretty and ego soothing, but it might just be too delicate

Chassis Engineering axles are forged

Most of the Speedway bashing seems to be on the HAMB Dave.

I use Superbell a lot and never seen a problem, On my own project i have a Chassis Engineering and its a very nice forging. On my 32 i have a aluminium Superbell but han't put that many miles on it yet to say although it looks nicely made.

As for the NSRA UK site the changes were made by the former committee who have now been mostly replaced, However i wasn't in favour of limiting non members posts as it is now fairly quiet considering it was once a very busy forum, I'm no longer a moderator there either.

I believe so are the Socal axles.

I seldom go on the HAMB - I got tired of the holier then thou attitude - if it isn't traditional, then you are ...... well, let's just leave it at that.

Maybe I should look in on the NSRA UK site again as for the most part I enjoyed most of the threads. Sorry to see that you aren't a mod there any longer. Interestingly - as many times as I've been in the UK/Scotland and Ireland, I have yet to see but one rod, and not sure about that one.

CE had a real nice exhibit at the York NSRA show last week. I do like their bolt on IFS system, tho would probably weld it up once in place and proven.

Check to see what revision axel you have (I am sure there are noticeable changes) and wether the changes to make it stronger give you a better feeling for safety. The chrome embrittlement issue? Depends on the design of the axel and what design rules were used for over kill if any. Heck don't use it too scarry!!
