Nope! I think you just need a 9.5

BTW welding the tubes to the center does not prevent it from boeing, It's to prevent from twisting and possible leaks from the added stress...

Yeah, that's what I figured. That's why I was concidering a truss. I found the correct wire to use to weld the tubes. I think I'll just start there with a trutrac some good axles and a t/a girdle. In my search for info I found a few dmax swap guys running the 9.5". One runin real fast since like 2006 with out breakage. So with mine bein more street than race I should be good to go.

So here's hoping for a good $$$$ deployment this winter. I'm really excited to do this swap. My wife loves diesels too so she is ready to help, which makes it all the better.

Yes for the SS style with the smaller bearing you can have custom forged axles made. They start around $350 deppending on options ss style would be 1.622 Shaft

The larger style you can not get an aftermarket forged axle made. This is roughly 1.703 shaft

So for he large bearing it's just a better alloy and for the small it's a forged? Now I'm confused cause I thought forged axles didn't like the bending load or is that the billet style axles. From my research I read that only full floaters could take the harder axles cause of no bending load. Of course it's hard to search through the loads of crap and good info out there with out calling someone.

Who makes said forged axle?

Well actually all Axles are forged even stock axles. Its the metalurgy that use that makes them stronger. I only contacted Dutchman and Moser, and both said they could make a replacement shaft for the SS style 14 bolt from a stronger forgeing.

According to Dutchman a factory C clip axle is made from 1050 steel.
The stronger forgeing used is 1541-h

Read this it will better explain they type of axles and why there used for this application.

FWIW For the large style shaft we used stock replacement axles from Superior Axle. Even thought they bost about being an American company after talking to tech support we found out that these forgings are coming from India. There made to OEM spec but they claim these axles are a little stronger then original because of the Hardining process, the better tolerances they hold while maching the hat and the cold formed spline process Vs. a cut spline. They also Have a 10 Year warranty against Deffects.

I am sure I voided the warranty by maching the Hat diameter down a little bit but you can tell the difference between them and an original axle that I have in my possesion.

Ok that coincides with what I've read before. I've found the 1541-h axles for the big bearing style all over. It was the small bearing I couldn't find. But now I have, thanks. Is there really that big of a difference in strength from the big bearing to the small? I mean right after the bearing I think they both shrink down.

I wonder if somebody can make a 1410 yoke for the 9.5". They went to that on the 10.5 cause people were breakin the 1350 10.5 yoke with big torque (diesel) or with big tires. It was considered the weak link on the 10.5".

Yukon says it's big bearing axles are 1541-h. I'll have to look again.
