Hey guys, Stephanie with americanmuscle.com here checking out an extremely beneficial modification for you S197 V6 owners. We're going to be taking a closer look at this aluminum one piece driveshaft available for 2011 to 2014 V6 Mustangs. A one piece driveshaft is a huge upgrade over the factory two piece driveshaft for a few reasons. An aluminum one piece driveshaft will provide an increase in strength, shed some extra pounds from your Stang, and improve driveability. We could not resist these benefits here at AM, so we even installed some one piece driveshafts on project Coyote and on the original MMD car. Let's talk about the weight savings here. I do have a scale with me here today, so let's see how much this driveshaft weighs. It looks like it's weighing in at about 20 pounds which is almost 29 pounds lighter than the factory two piece design. That's really pretty impressive. Let me remind you that these are pounds that will be shaved directly off of your Mustang's rotational mass. When you take that much weight off of your drivetrain you're going to immediately notice a few things - faster revs and throttle response and even some faster quarter mile times. You will also notice that the one piece driveshaft will eliminate the vibrations that are commonly found with a factory two piece driveshaft. Another benefit here is the increased strength that I mentioned earlier. You're eliminating an inherently weak spot in the factory driveshaft due to the two piece design, and you're also going to be using stronger materials all around. Keep in mind the driveshaft is made from a certified 6061 aluminum. Getting this one piece driveshaft installed on your Mustang is actually pretty straightforward even if you've never done one before. A lift of course would make things a lot easier for you, but you can still do it the old fashioned way. Just leave yourself about two hours from start to finish to get the job done. Make sure you have a torque wrench handy just to keep everything in line with specs. If you guys have any questions about the one piece driveshaft or the install, you can always give us a call or shoot us an email and we'd be more than happy to help you out. Even though upgrading the driveshaft can be a little pricey, the benefits far outweigh the cost here. The numerous improvements over the factory two piece driveshaft are worth every penny. Be sure to check out this aluminum one piece driveshaft for your '11 to '14 V6 Mustang available right here at americanmuscle.com.

Good drive shaft
I'll start by saying I have upped the horsepower by at least 50hp and did a rear gear change had 2.73 to 3.55. So with the added power and the added rotation with the gear change it was about safety for me. My stock drive shaft weighed less than the new one. The steel was just that thin. It was cheap. I'm not worried about it now. I would have liked to spend that money elsewhere but I don't need the old drive shaft braking on me and doing other damage to the car. Like I said I was thinking more safety than anything else. Oh I did it on Jack stands and didn't have to remove the exhaust.Helpful (1)

BETTER THAN NEW
After 8 years the original driveshaft was worn out. Been reading about failures for the stock unit, time to change! The SR driveshaft is well built, nice welds and a perfect fit for my 2011 coupe. Keep in mind when installing, you may have to index on the tranny side to get the balance just right. Go for a test drive, if you have any vibration, disconnect from the tranny and rotate to the next set of holes and test drive again. Noticable improvement over the old one, when coasting in gear at highway speeds, no load applied, car would undulate, rumble from rear, not any more!Helpful (3)

Great on stock ride hight
I bought this at the same time as my Eibach Pro Street coilovers, I tackled this first and drove it for a while before doing the coilovers, it was very impressed, almost completely eliminated the trans vibrations my 14 suffers from, there was still a hint when costing in gear but it was a lot better, acceleration seemed a littler quicker, impressed with build quality over all. installation was tricky with just jacks, recommend loosening the exhaust, definitely not impossible though. The problem comes in with the coilover install, now with a even a 1.5 inch drop it rubs the plastic covering under the fuel tank, not enough to really damage anything but it definitely rubbed some plastic away, I currently have the stock driveshaft back on until I can get the 3.5 inch drive shaft ordered. the 4 inch is great, just as long as you don't plan on lowering it.Helpful (1)

Definitely worth purchasing even though expensive, the response and lack of vibration make up for the money spent. I run 355 gears and have a tune, you certainly notice less bog with standard shift as the effort for take off in any gear is much easier, slowing down to an intersection in forth would typically require you to down shift, I now find no need to as there is less weight to turn and better response. The only thing I noticed is a whistle, it’s not bad but noticeable, and I forgot to mention at 130 mph the car is smooth, no vibration as with the old drive shaft that doing above 100 mph you wondered if car was going to shake apart.Helpful (1)

This is the very first thing to do period!! Get that 2 piece junk out of your car. Put the 1 piece aluminum drive shaft in. Next K and N Typhoon a must have. Borla Stingers axle backs. Bama tuner 93 performance tune. Koni struts and shocks and last thing drilled and slotted rotors!! All from American Muscle you will love it and it’s done right!!Helpful (2)

4” Driveshaft Upgrade
Super easy to install, but not much lighter then stock. There isn’t a noticeable gain other than a little less vibration in the shifter at speed. The cost is really high for this and you could have a driveshaft shop build you a custom one for cheaper. I only added this as my car is being procharged shortly and I needed it to help handle more power.Helpful (1)

No more clunking
I installed it on a 2012 V6 auto and it fit well, but I did have to wrestle with the exhaust some to fit it in. Raising the rear helps the drive shaft clear the pipes but if you are doing it on jack stands be careful. The car shifts more firmly and the vibration and interior noise are noticeably less. It makes all the difference.Helpful (4)

Throttle response is definitely alot better. Absolutely need this if you’re going to add more bolts ons and tune it.Helpful (4)
What speed is this shaft rated for? I have heard that the stock shaft on the v6 fails at around 130. The reason I would buy this is to increase my top speed & acceleration. So what top speed do you think I could achieve without failure.
Stock fails at 122 why cars limited to 118. I have this drive shaft an its smoother an have had my car up to 160mph many times without worry. But you will need better tires. Its a great buy. I run 18 Weds Sport TC005 255/45 General G-max tires. Amazing dry/wet traction.
Maximum rated HP and maximum RPM? I come from Germany and we have no speed limit on several highways. Therefore I would like to know the maximum HP which can be applied to that Al driveshaft and the maximum RPM for that driveshaft. Can the driveshaft itself handle 5500 RPM (driveshaft rotating speed)? It's something around 160 mph.
Oliver, when I contacted the suppplier regarding the same question, they said, "The shaft can handle up to a 1000HP" With regard to the RPM, they said they can guarantee up to redline operation of engine (6800-6850RPM) at top gear. For the rotational speed of the shaft, I am guessing it should be safe until 8500RPM. You have detailed articles in the internet, about the RPM limits of the shaft by itself, classified as per material, Dia, thickness and pinion angle. I would suggest you research that...
How does this item compare to the Ford one-piece drive shaft (M-4602-MGTM)? I gathered from the video they're made of the same material (6061 aluminum), and I'd assume the same wall thickness (0.125"). How doe the universal joints and flange yokes compare?. Who is the manufacturer for the universal joints (Ford uses 1350 SERIES Dana Spicer 5-1350X, this only specifies "1330 series"). What is the flange yoke made of (again, Ford uses 1350 series)?
The SR Performance Aluminum One Piece Driveshaft will use 1330 series U joints which they source from several manufacturers. The 1350 U joints will be stronger than a 1330, however a 1330 is still stronger than the OEM U joints. The flange yoke will be made of 6061-T6 aluminum to accept 1330 U joints.
Clearance Issues? My 2011 v6 has a 2.5" catback exhaust and I was also planning going with the eibach pro system plus to lower the car (1" in the front and 1.5" in the rear). Seeing that the stock driveshaft is 3.5" and this one is 4", will there be any clearance issues?
I have the Eibach Pro springs and a 2.5-inch cat-back, and this drive shaft clears everything just fine. Of course, I'm not off-roading either.
Would there be sufficient clearance between the 4" diameter driveshaft and the bracket, if used with a Blowfish Racing shifter support bracket on a 2011 3.7L, or would it be wiser to go with a 3.5" diameter driveshaft?
The Blowfish Shifter Support Bracket will have plenty of clearance with the SR Performance Aluminum One Piece Driveshaft.
Driveshaft loops should be slightly larger than the driveshaft itself. Though, if it is excessively larger, you may want to go with a loop that is adjustable. I recommend the Stifflers Driveshaft Safety Loop (11-17 All, Excludes GT350 & GT500), item # 394141, (http://www.americanmuscle.com/stifflers-driveshaft-safety-loop-1117.html). This loop has height adjustments for larger aftermarket driveshafts which can take up excessive slack.
Unfortunately we do not have access to those specifications, you will want to contact the manufacturer directly.
No, removing your exhaust would not be necessary. We have an install guide available on the product page if you wanted to take a look at the install, I can lend the link below: https://www.americanmuscle.com/aluminum-driveshaft-2011v6-manual-install.html
SR Performance does not currently have a maximum RPM rating available.
This may require pinion angle adjustment yes.
This will fit your car with stock control arms yes.
The torque specs for this driveshaft are 75 lbs/ft.
Depending on your ride height, you may or may not need to adjust pinion angle. Typically at stock ride height or lowered less than an inch you will not need to, but lowered over an inch you will most likely need minor adjustment to get the pinion angle within OE tolerance.
Sorry to hear that you are experiencing issues with your new driveshaft! I would definitely recommend bringing it to the attention of the shop who performed the installation, if you have any additional questions please feel free to reach out to our customer service department at 1-877-887-1105, we are available 7 days a week between 8:30AM and 11:00PM EST!
We do recommend getting the BMR Front Driveshaft Safety Loop, item # 49605, (https://www.americanmuscle.com/bmr-ds-loop-1112.html) for added safety in the event of a U-joint failure.
