OK. Suppossedly Moser alloy shafts don't have heat-treated yokes.

But their shafts are still chromoly.

So isn't a non-heat-treated chromo yoke still stronger than a stock Spicer yoke?

Where did you hear that the ears were not heat treated. I would not make sense to me because i am pretty sure that types of shafts are treated equally throughout. Besides it would be more expensive to come up with a way to isolate just the ears from the heat treating process.

I got one to add too does anybody know if they have inners in custom lengths.

Ian-

Have not heard of anyone trying them yet. I think their warrenty or lack of has caused some concern.

I heard that about the ears on this BBS. They do make inners in any legth that you want.

They don't bake them in an oven, you know! :D

They're INDUCTION hardened....

What's that mean? And do you know if there's any fact behind the myth that they don't heat-treat the yokes?

ok...here's the facts--- http://www.dreamwater.com/zuk/detroitsoftlocker.html --- notice where it went bye-bye...also notice how soft the ear material must have been to deform like it did. As you can see, the 297 UJ lived and was not the weak link in this combo. That's a Moser Custom alloy axle there.

oh ya....I e-mailed that link to Moser and said that I didn't think this should happen to a Moser....I never asked for a warrenty and really didn't care. The fellow was polite enough in the response...said that break seemed unusual and to send it in and if they thought it was a defect they would warrenty it. I did this instead and now all is at peace with the world. http://www.dreamwater.com/zuk/warnaxle.html

Sorry, but just the opposite is true, all Moser axles that I have seen are induction hardened out of 1541H alloy steel, the induction hardening process is much cheaper that thru hardening, and you can use chaeper materials than when you thru harden. The problem with induction hardening is that you can't heat treat an entire part that has big diameter changes, as result, in mosers case, they don't heat treat,the ears on a front axle, and the flange on a rear axle.

spicer only heat treats the shaft and not the ears all day long.

If you look closely, you can see where the heat treat stops on this spicer shaft.

I don't know anything about their hardening process, but I AM running a D60 custom length inner alloy Moser axle shaft. Hasn't broken yet, will report when or if it does.

I've heard the stock Spicer shaft is 1541H.

Is Moser just selling the Spicer parts are calling them "alloy"?

What's that mean?

Induction hardening is done by placing the metal part inside or close to an "applicator" coil of one or more turns, through which alternating current is passed. The coil, formed to suit the general class of work to be heated, is usually made of copper tubing through which water is passed to prevent overheating of the coil itself. In most cases, the work piece is held either in a fixed position or is rotated slowly within or close to the applicator coil. Where the length of work is too gret to permit heating in a fixed position, progressive heating may be employed. Thus, a rod or tube of steel may be fed through an applicator coil of one or more turns so that the heating zone travels progressively along the entire length of the work piece.

I haven't seen Moser's shop...but I guess that the shaft is passed through the coil, and the coil has to be of a small enough diameter so that it is close enough to the shaft to do the heating, but that diameter prevents the passage of the yoke or flange (as described by Goat1) through the coil.

i think that the ears on my moser axles are much larger than the stock ear,, ill have to look for sure,, i had talked briefly to the guy before i ordered them i remembered he said they where alloy,, and i asked him if they where chromo and he said no,,i dont know how much stronger the 1541h than stock if any,, there has got to me someone that can make stronger shafts out there,,,i will keep the yall posted on how my ears hold up
