I am getting an aluminum driveshaft shortened two inches tommorow. No concerns were raised by the driveline shop.

I cannot see the logic in this either. I just wanted to get others opinions here. If it was a sales pitch, then it doesn't work when everyone elses comparable shafts are $200 less than yours across the board.
well no need to be like that now just trying to share info??? you don't even know what my drive shaft is so how can it be comparable
Good luck with your situation
I think he was refering to the driveline shop's product with the "yours". Their's is $200 more than everyone elses, not your's.
At least, that's how I read it.

Apparently, the bonded ones cant be shortened, an experienced chassis guy over here tried welding one and it wouldn't take, he said that Mark Williams were not very forthcoming with the type of alloy they are made from. I have got a welded one which i'm having shortened, so i'm interested in the outcome here. Mike

Now I'm confused. 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.

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.

Dont give up yet! The only problem I see with shortening a shaft is the amount of change in the length. 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

If the need to shorten it is caused by just the thickness of the mid-plate, that is probably the case.

The length of the drive shaft is not my only problem. I have also changed engine combinations and the new engine will put out 100+ more hp and the shaft is only a 3 1/4" dia shaft. Nobody I have talked to recommends it for my application that I have now. This is the reason behind my switch from wanting to shorten it to just replacement. If the car was lighter I could get away with it. Everyones comments tell me that they were simply full of it though.
I must have misunderstood the question.What is the issue of application?I see many big tire,hi hp cars running a similar 3-1/2 aluminum shaft even a few at #3400?We also have many heavy duty,hi torque trucks in our construction fleet with aluminum and aluminum/composite shafts.

Who did you talk to at MW? Travis is always a big help to me over there.... I am surprised that's what they told you, but they also may not like the 3 1/4" shaft. Everything we use from them in AL is 4". Just a thought
Ben,
It might have been Travis that I spoke to. I hadn't even mentioned that the shaft was 3 1/4" dia. before he told me that they can't shorten it. Nobody that I called recommended a driveshaft smaller than 3 1/2" and about half of them suggested 4". I want as small as possible though since I have little space in the tunnel with my tubular driveshaft loop.
