Are you still on the stock MT 82 with the power numbers in your sig ?

I just got my RMA from DSS, will send the shaft out within the next few days. As to what I do once I get it back or a replacement back, IDK. I plan on staying N/A for a while if not forever and am not a drag racer so don't need the strength. I may just post it for sale once its back and "good".

If you have FI and launch with sticky tires, be careful with the stock driveshaft. The pics below show what I discovered with mine.

Can't you just dump the clutch in reverse?

Well shiiit, just bought one of these ha.

Shaft sent in...now its a waiting game.

Side Note: seems to me there is a market for a stock style (2 piece) shaft which is "forgiving" like the stock unit in terms of vibration/angles/NVH, but made of tougher materials, stronger U/CV joints and a beefier carrier bearing.

Did you experience any vibes from that?

I did not notice anything unusual, which is what I thought was especially scary. I had purchased a DSS shaft that I had found used, went to install it and was shocked to find everything mangled when removing the OEM shaft.

Any updates?

I too ordered from a "very reputable sponsor" here, but they are holding firm that they need a professional shop to determine that its the shaft that is faulty. Until then they are holding firm on this portion of their return policy:

"We will not accept a return of an item that is damaged or defective if it has been used/installed please inspect all orders as soon as you receive them and contact HERE within 72 hours."

I am also talking to DSS direct, but looking like they are leaning towards blaming my Steeda poly diff bushings :doh:. Now Steeda sells DSS shafts, should I see what they have to say...seems like it couldn't hurt.

Car is back to smooth as glass with the stock shaft, but iv got what's looking more and more like a $760 aluminum turd laying on my garage floor.

So wait they want you to get a driveshaft that is supposed to work when its sold....inspect it without putting it on which would mean In 72 hrs of receiving the product you should pay a speed shop to test the item to see if you can get your money back on a product that should have came right in the first place are they saying their products aren't tested and proven before selling implying the borrower should buy then go get it tested at their own expense... I would dispute the charge and bash them on here until they came up with a resolution and make sure I let everyone know of their faulty products.

could be worse,you could be this chic
skip to 5:30......I think the companies has not mastered the S550
yet.......I was gung hoe for a shaft,now im not touching one..
Id rather have a 3" chrome moly one piece shaft than AL or CF

Wow that’s crazy I haven’t seen that before. CF shaft demolished in shreds.

That's very crazy and scary! Definitely puts me on pause for purchasing an aftermarket drive shaft. Yikes!

Finally drove my car after installing a DSS 4' Aluminum DS last week, it vibes and makes a terrible noise, basically undrivable.

Will have to go back to the stock shaft unless there is a fix or something different to try.

My first CF was shipped with a bad CV joint -- had some vibrations around 60mph. The first one they replaced it with was for some other application -- I think the guy in the shop might have been smoking something. On the third try, I finally got a good one that worked. The CV joint is a maintenance item -- I may go with something else when it needs to come out for service -- so I'll always have a spare. I may go with whatever Kelly (aka BMR_Tech) is running in Project Stockonaut. That looks like a nice unit -- but who knows. It seems like some aftermarket parts might not be worth the trouble...

This is my thought on this -- I bet her driveshaft was rated for 900hp, while they might have been underrating the power she's making: The twin setup she has is configurable for up to 1200hp - unless there are quality control issues at The Driveshaft Shop (very possible), I would expect something like that might be going on. I'm not sure what kind of longevity to expect from a CF shaft -- everything leading up to the purchase of mine had me thinking it would last forever... They aren't supposed to fatigue even with regular use right up to their rated strength.
