2011 Mustang Driveshaft problem. Aftermarket Solutions?

I know the 2011 Mustang V6 has the driveshaft problem at around 135 mph and I was wondering which aftermarket driveshaft would be best? Thanks!

They are all an improvement over stock. I do not believe anyone has had trouble with any aftermarket driveshaft. American Muscle has one for under 700 and I believe there is another for around that price range but I cannot think of the name.
I have a Dynotech and like it. Had it on for about 3 months and all is well.It is well made and looks and fits great. great.

I cannot speak to 135 mph though. My car has seen brief sprints to just over 100, but I doubt it will ever see higher speeds. That is, unless I decide I want to see what our local jail cells are like. :winks

Dynotech would be my first choice, can't really go wrong with any of them though
My Axle Exchange from American Muscle has been perfect.
+1 on Axle Exchange from AM
Thanks for the recommendation guys!

I haven't seen anything but good feedback with our aluminum one-piece driveshafts and I know they go through a hard beating. Needless to say, I think you'll be more than happy with one.

If you have any questions or concerns about our products please feel free to hit me up!

Ordered the AE driveshaft from american muscle. Should be in early next week. I've had some vibration issues that I think could be stemming from the driveshaft so I'll chime in on this thread once its installed with my impressions.

Another vote for Dynotech. They are the lightest of all options, spun to 8,000 rpms and use universal joints for maximum reliability. I had my car on the lift the other day and after almost 40,000 miles, it still looks shiny and new.
Yea, Dynotech makes a good shaft, both on the highway once and on the dyno I had it up to 130. Probly not going to do that again tho, at least not on the street. Not worth the legal consequences haha.
Blaseleblanc, since you have an auto, then yes it may be the driveshaft that is causing some vibration.

Yeah it's boiled down to one of three things:
1. One of my wheels are warped or off balance
-I rotated my tires and found that the vibration almost completely disappeared, but then started to come back slowly as I put more miles. Now I can feel some pull in the steering and the vibration moved from the back center of my seat to the bottom front of the seat and footwell. The issue only happens at certain speeds/RPMs, however, and I feel that a bad wheel would cause issues at all speeds/RPMs.
2. There is an installation error or issue with the stock driveshaft
-A million things could have gone wrong when my gear shop was reinstalling the driveshaft. However, I've been battling this same vibration for a good 6 months now with no increase in severity. According to my gear shop, the 3.73's are putting a lot of rotational stress on the DS which is causing the vibration.
3. Something is about to blow up in my differential
-I don't trust that my shop used the right bearings or housing. Not to mention this all started happening right after my gear swap.


Not sure how to differentiate between the three because the vibration only happens at certain speeds/RPM's but I went ahead and got the DS because I track my car and I hear it dampens vibrations heavily. It's something I'd need anyways. I plan on balancing my wheels/tires before I install the DS in hopes that it could fix the issue.

oh, with tires rotated, then I would have alignment checked.
I've got nothing but good things to say about my axle exchange shaft. Honestly though, you can't really go wrong with any of the aluminum shafts :bigthumbsup

Not wanting to start a new thread, but interested in finding if anyone has dealt with Mark Williams driveshafts? Read an article where they talked about how they build their shafts, and it appears they also do work for NASCAR spec cars. It sounds like a good product and a street worthy shaft is decently priced.

Since our DSs spin at higher speeds, you need to ensure they are designed with that in mind. There are only three companies that spin shafts up to 8,000 rpms: Precision Shaft, Driveshaft Shop, and Dynotech. Only DSS and Dynotech sell shafts for the 3.7.
