    Good morning all

    I'm shopping around for a driveshaft and found this one at Summit.
    https://www.summitracing.com/search...hafts-steel-driveshafts/part-type/driveshafts

    I know this is not a performance shaft but would it be good with a mild 283 in my model A.

    I have an estimate from a local driveshaft shop for a custom shaft for $500 which I think is reasonable considering there will be no shipping $exchange etc, and I'm sure it's a better shaft, but do I need better.

    I'm also to much of a woose to go wandering the the pick and pull at -20c :rolleyes:. Although if it is reasonable to expect to find something about 30" long I could wait till spring.

    I didn't get get a estimate to shorten a pick and pull shaft but I know this could be an option.

    Thanks in advance Phil

    You might try speedway motors.I got my 32 shaft from them.I don't think the odds of finding a late model short shaft are very good.In my area shops that can build shafts don't want to shorten oem shafts they push their own new made to length shafts.Many larger cities have a drive line specialist shop that do truck,farm equipment work,and will custom build to your specs.

    Why would you not go to a local driveshaft shop with a good reputation and have one made there rather than taking a chance on a mail order unit? You load the car up, take it to the shop and a few hour later you have a custom made to fit your car driveshaft installed and the total cost probably will be less than some mail order shaft that does or doesn't fit plus shipping and other fees to get it into Canada. If the car is shop bound you might even get the local guy to stop by the shop and measure it and make one.

    Although I'm not a fan of Speedway having examined their driveshaft offerings I can see the attraction - I can't imagine a local shop could come close to $150 (but shipping is presumably a further cost consideration). Never seen pre made driveshafts available in what seems to be 1/2" increments, most convenient!

    Having said that, if I'm reading their listing correctly, they're all 2" diameter tubes, which seems kinda skinny to me. I might be out of touch with modern methods but I don't recall any shafts of that diameter being used on anything with any decent power / torque on tap. I'm sure some wag will prove me wrong though! I bought a custom made steel driveshaft last year and it must be 3" diameter.

    In my '27 T roadster, about 550 hp, I have a custom 3" aluminum driveshaft. In my '26 T coupe, about 250 hp, I have a 2" Fast shaft from Speedway. It comes balanced. It now has 22K miles on it with no problems. Can't beat the price

    Find a shop that builds and rebuilds off-road trucks, installs serious lifts, etc. They build driveshaft all the time. That's who did mine.

    I have complete trust in the local shop (they shortened a shaft for me 40 years ago). If I need a $500 shaft that's fine.

    The Fastshaft would be 1/2 of that by the time it gets here so if its suitable for my application, why not?

    $500 is wow! Holy crap! Guess i need to go hug Steve at the driveshaft shop. I've bitched when he charged me $125 for a new shaft. He'll shorten and balance one for $30-$50

    We Have used the speedway shafts in a lot of project very. They work very well and can sometimes fine tune the length with a longer yoke ect. Yes if you try to drag race with slicks they will fail.

    My local shop has NEVER been that much. I find it so much easier to take a dimension down to them and come back 2 days later to the exact thing I need.

    Thanks for the responses. There's not any competition for this service here also remember I was talking $Canadian so 500 is 375 $US right now.

    When I last talked to a driveshaft shop, they told me that the longer the shaft, the larger diameter is needed. I needed a 3" for a Model A, small block chevy with 200 4r tranny and Ford 9" rear end.

    Just had one made for my Plymouth at my local shop with used shaft and slip yoke but 2 new universals and balance for $179...
     
  20. There’s only one guy here local that does driveshafts. He’s $400 Plus plus plus plus usually 500 OTD.
    I’ll shorten them myself because it’s not a big deal at all. More often than not if you don’t cut the weight off and weld semi consistently it won’t need balanced. Of course it’s sent out for balancing but just comes back without needing any. If I need a new or different stub he’s got them on the shelf.



    Now The welding out of that place is butt fucking ugly. I told him a few times I’ll weld all his shafts for him. He claims the welding doesn’t really cost him anything and it would be more of a PITA for me to do it.
    Now when I need a drive shaft I tell him to build it, tack it and call me. I pick it up and weld it and take it back for the assembly and balance. I always set those or one I’ve shortened and welded next to some of their gum bullshit and remind him about my offer.
