CF VS Aluminum Driveshafts, Pros and Cons.
 

I am at some point going to be adding a 1 Piece shaft to my car, I have gone from Steel to Aluminum on older Camaros before and definitely noticed the difference.


What are the Pros and Cons of each?


Is there a smoothness and noise difference?
Longevity?
I don't mind spending a bit more if it is worth it.
Is there any difference in drive ability?

Thanks you

I've had both plenty of times. I can't recommend one over the other for any noticeable difference. "They" say the CF is stronger but I haven't seen an alum get thrashed due to power.

I've experienced the epoxy give way on the early CF driveshafts (rear joint to yoke). Quick RMA and the issue has been resolved and haven't had a (re)occurrence (been 5 years ago). They say if the exhaust to too close to that joint then problems could occur (wasn't my issue - it was the epoxy cure process). The CF is no quieter and will act as a speaker to noise in the driveline (like the alum will). Weight-wise, the CF is a little lighter but I don't think that would affect anything.

Said and done, the alum is less expensive and would suit almost anyone's need for a stronger driveshaft. Just my two-cents.

SO you are saying you didn't notice any noise or Vibration/Harmonics between the 2? To Me smoother and less NVH is worth something.

I did not notice any NVH difference with my 9"/ZL1 diffs. YMMV.

DSS claims to balance the CF at 10k rpm. I calculate I would be turning the shaft 9,745rpms when at 200mph. So, I guess that's a good calculation if you're going to run stupid fast (the mile run). I think mine is a 4" (might be 3.75") I obtained with my DSS 9" conversion. I see DSS has the CF 3.25" and 3.375" listed. Alum's are 3.5" and 4".

CF in mine, road coursed with it. Dreksnot is spot on with his analysis. I like the CF but either will work - it's only money ;o).

Only Like a $700 difference, its only money lol. I don't plan on getting rid of the car any time soon and I have learned to kinda do it the way you want the first time. I am sure the aluminum would be find but I have heard some people complain about a vibration issue and I really am trying to avoid that, That is the one reason the Hendrix offset bushings are sitting on the shelf.

Definitely saw a little more NVH with the aluminum, but I don't hear so well anymore so not a big deal. No experience with the CF.

I have heard that with Aluminum. CF I believe is quieter.

I also have the Hendrix offset on mine too ;o)

I have the 3.5 inch aluminum one in my Camaro from DSS and really love it! A little more NVH, but not too bad, and I also have the solid cradle mounts as well. Both are good shafts, but if you don't really need the CF for racing purposes, why pay the extra money if you don't have to. The aluminum one will be just fine.. Had mine in the car for about 1.5 yrs now.

I agree with the Extra cost and maybe not needing it, But I I do hear a few stories of NVH increasing a lot on some cars with Aluminum shafts. If I can avoid that then the extra money is worth it to me. my Z/28 I have had for over 25 Years and I plan to keep this one as well.

Anyone ever deal with either of these companies?

I ordered an aluminum one from gulf coast driveshafts a little over a week ago. https://www.gulfcoastdriveshaft.com/.../ds-cssa-g535/

Shipped on Monday, received it on Wednesday. Unfortunately they sent a 6th gen shaft. I sent it back and the correct one is due to arrive Monday. Mistakes happen, customer service is top notch and they dont mess around. Owned up to the mistake and got me taken care of quickly.

The 6th gen shaft looked very nice and well built.

looks like a nice product please post back, I am trying to avoid NVH/Vibration that is why I was leaning towards carbon. I have read quite a few issues with DSS Aluminum shafts causing NVH/Vibration.


DSS seems to be the most popular for these cars but that maybe because these other companies don't advertise the 5th Gen shafts well.


On Monday I am going to call these companies and ask them a few questions. I think I would prefer an aluminum shaft if it is smooth.
