Aluminum Driveshaft

But, what about the noise and vibration. I was reading on the description on the Suprasport website that the aluminum greatly reduces the noise compared to the steel one. What's the price of the steel one from Jawsgear?


Sorry about all the questions everyone, this is just a big purchase and I don't want to regret anything.


Smooth as ice allway up to 120 :naughty:
I do hear a slight harmonic noise at 80 where i spend most of my time, but its hardly noticible , and 99% of the time i dont hear it. For reference i spent over 500 to get my mine there the next day, and i dont regret it one bit.The only problem ive had, was after installing, my output shaft was destroy'd on my tranny and i could have fubar'd my d/s if i didnt catch it in time, so i ended up having to buy a new tranny to boot, all because my old d/s broke with style.:)

Al is has more elasticity (sp?) than steel correct? Say if you were jarring down on a car with some serious torque (enough to noticably twist the DS some) the aluminum one would allow for more give, correct?

Here's another newb question....What's the weight of the stock d/s and carrier bearing, weight of Jaws steel d/s and weight of Jaws aluminum d/s?

Nope ;)

To get the Al shaft as strong as the steel shaft it will be thicker in the walls so will be quite stiff (Don't know if you mountain bike at all but steel frames are more lively than Al for this reason).

The Al shaft will dampen the shock loads but each time it does this it's work hardening and can only cycle so many times before failure.

Al does have a finite lifespan in structural applications but how long this is in this case I have NFI.

I was going to use the same MTB analogy. Nothing like the sound of an alum hardtail though when bombing DH. Or the challenge in keeping it under your ass...

like Ian said, the Alum driveshaft does in fact have a critical limit on its fatigue life. Unlike steel, which if cyclically loaded up to a certain point, can go on forever without failure, Al will always have a "cycles to failure" limit. Keep in mind that i have no idea what this would be as it is based on the alloy used, the quality of manufacturing, and the shape of the shaft. Personally, my car will be driven quite a few miles once it gets put back together so I'm going to opt for the steel shaft. If I was going to be building a drag/show/weekend car, I'd likely go for the Al. YMMV.

I think that I'm going to go with the steel one for you just said and for the price factor. How much I have changed my mind during this thread. So, who knows what I finally decide when I get the money. I appreciate all the comments.

Are you on drugs? If you think this, then why are you driving a Supra and not an LS1 powered Camaro, or an old 5.0 Mustang. You kids just don't make any sense sometimes.

what ds are the posters using?

i was reluctant to use a jawgears ds because it's mentiond that can not guarantee about vibrations.

input and sorry to hijack.

i hava a DSS alum and haven't had any problems, but I like the JAWS design better. I did notice better shifting though, especially from a stop.

I'm glad I know about the whole deal with the lifespan of the AL shaft now, If I ever decide to get one (I like the smoothness of the 2 piece) then it would either be a modified two piece, or a one piece steel, thanks!
