Can't shorten aluminum driveshaft? #273949 04/01/09 02:48 PM 04/01/09 02:48 PM

They said they can't shorten aluminum drive shafts??? I know I should have asked, but can anyone here tell me what the reason might possibly be that they can't shorten it? Guess I will just have to sell what I have and get another then. Someone will get another screaming deal in the parts section.

As far as I have been told you can shorten them once but after that you need a new one for strength & reliability which gets expensive [image]http://i682.photobucket.com/albums/vv183/DrDart500/DSC00307.jpg 1966 Charger 1970 Dart 16-1,solid roller,500 ci Tunnel Ram 8" Ati conv,BTE glide, Fab 9 rear strange center sect.

Their's is $200 more than everyone elses, not your's. At least, that's how I read it.

I have got a welded one which i'm having shortened, so i'm interested in the outcome here.

I can understand why the staff was told to say "it can't be done", because of legal issues, etc. If the ends are deeply inserted and mechanically locked (spline/flute) in the tube before welding I'd think it would be a nightmare to try to un-do or re-do this. But.. why would a weld cutting only the tube itself not be possible? Can't be strength - if you move down the tube 6" so the area hasn't been heated at all, a simple sleeve or stub insert makes the new joint far stronger than the original tube with only a few ounces lost.

I have got a welded one which i'm having shortened, so i'm interested in the outcome here. Mike It is their welded version and the tube is clearly marked 6061 T6 aluminum. I am sure that the tube has a short register in it to maintain concentricity and then is welded. I don't believe that it can't be shortened. It might be cost prohibitive to do, but not possible? Anyone need a shaft for a 727/Dana 60 111" A-body? Guess I will post up in the classifides and get a new one on order.

Under a 1/2" may not be possible because of the previous welds width that needs to be cut out to get to fresh tube. mike Last edited by Sport440; 04/02/09 12:17 AM.
