I'm Building Some More Custom Axle Shaft Set Ups For D80's And I'm Considering Using A New Material And Wanted Some Other Opinions First. Normally I Use 300m For The Axles And I've Had Good Luck In The Past. But When I Talked To My Supplier Last Week They Told Me They Had Something That Was Holding Up Better Than 300m In A Drag Car. (example: This Particular Car Would Only Get Maybe 15 Passes W/300m Axles, And Now W/ The New Material They Have 50+passes And Still Haven't Broke) What They Are Telling Me Is That The New Material Is More Elastic And Able To Withstand The Shock Of The Hard Launches. So I Wonder If This Material Would Also Work Better For Truck Pull Applications. I've Never Drag Raced And Don't Know What Kind Of Axle Strain Is Applied V's Truck Pulling. Any Input Would Be Great.

Thanks Jason
 
I think that drag racing would put more of a shock to the axles and truck pulling puts more of an even load to them. However I believe that you would probably have more load when truck pulling than when drag racing just not one big shock to it. My 2 cents.

Drag racers tend to shift more....
 
Are drag guys breaking axles like pulling truck guys? Travis

IMO, go with what you know. if you are only concerned with building stuff for sled pulling, and you have no problems with the stuff you currently have available then why change?
 
I think that in sled pulling there can be many instances where the axles see a great deal of shock during any given pass so they too might benefit from this new material. Most of the axles I have brokem sled pulling always looked like they had been twisted or fatigued before the final break. So if this newe material allows some flex, IMO it should help them live too.

Same here when i had the dana 70 in my truck.

But i say try them onces and see how they hold up
 
no, it actaully has a better flex strength then both, it has less tensile strength like twisting, but they say under a good load with bigger and wider tires 1541-h would be better, idk never ran them just a idea.
 
So what is the material? Maybe some of us with metal experience can help more if we knew what we were working with.
 
As I have been explained to by a very knowledgeable metallurgist. It doesn't matter what the material is, if the heat treat is wrong you might as well make them out of wood!
 
I drag race and sled pull and break axle shafts when i pull not race. last axle shaft went as the weight was hitting the truck at the end of the track.

Whoever told you that, has no idea what they're talking about.

PT, unless someone is willing to cough up actual specs on the new material, my attitude would be "so you believe in these so much that you're warranteeing them?"

Otherwise you are likely engaged in someone's R&D program as an unknowing beta tester.

You have to understand the stress state the axles are in, and then compare almost every aspect of the processing and final heat treat steps with multiple location hardness testing (and maybe more) before you can truthfully and scientifically say B is better than A.

There are probably a few alloys out there that can outrun 300M.

If you want to send me some detailed info, I might be able to help you out. I are a metallurgist :doh:
