  Must Have

  Just installed aluminum driveshaft yesterday and I could feel the difference right away - car feels more responsive and being lighter it has to be easier on the engine. This is a must have for any 2011 Mustang GT ****

  AM aluminum driveshaft

  I have AM's driveshaft on my Roush TVS blown 2011 GT. It ran 9.89 in Maryland on 3-25-11 weighing 3805 lbs with the stock longblock, tranny and converter. I bought another cheaper d/s only to return it because it vibrated. This car makes 670 rwhp and 611 rwtq and has run a best of 1.419 sixty foot on dot's weighing 3805 lbs! I have no concerns about d/s failure and it is vibration free. Is a very high quality piece. I have since bought another of AM's alum driveshafts for my 2012 Boss 302 Laguna Seca and there is no vibration at fuel shut off of 155 mph. It improved acceleration nicely and is a great improvement to the Ford two piece monster.

  Noticeable difference

  My car is a 2012 GT Manual with headers, Boss intake, Cold Air on a Bama tune. All of this is riding on Ford Racing Suspension with the K springs which is a 1.5 inch drop with TSW 19 inch wheels. I mention the drop because it will matter as you read on. Removal of the stock 2 piece drive shaft took about 10 minutes with 4 jack stands (rear axle supported by 2 allowing for a pretty level drive line) and air tools. Get the vehicle as high as possible as you will need to torque all of the fasteners and you need room for the torque wrench. The instructions describe the requirement to move the emergency brake cable bracket and to flatten any shielding in the transmition tunnel if the car is lowered from 1-2 inches. None of this is required for a 2012. There is plenty of clearance with the cars suspension at full travel. You really couldn't move the brake cable bracket easily even if you wanted to. You will need to remove pinion flange and replace it with the new one (this requires an impact gun or one heck of a breaker bar). Install took about 2 hours total. Several install write ups are available on line but I will tell you that a torque wrench capable of 140 lb./ft. and a 27mm socket. The resulting drive shaft angle (with the 1.5inch drop) was within tolerance and there is no vibration (tested up to 135mph). The reduction in rotational mass is most noticeable accelerating from low RPM. The car feels lighter and revs faster. From 1500-3000 RPM the car is snappier with less throttle needed. It was well worth the price and is a quality piece!

  Faster 60' times

  Great bolt on for any level enthusiast. I dropped .6 seconds off my 60' time, .3 off my 1/8, and .28 off my 1/4. No NVH that I can tell. Definitely worth the money.

  Aluminum one piece drive shaft.

  Well great news guys !!! This is definitely a upgrade. Once you have removed your old 2 piece drive shaft one will notice a big difference in weight. I would not believe i was installing this shaft without having to use my car on a lift. Heads up on installing, relive the rear exhaust to allow a more comfortable access to the bolts you will need to remove. This installation is definitely not for beginners. Not all the bolts removed will have thread lock applied so it will take extra effort in removing the stock bolts. The new bolts provided will be applied with thread lock but remember to re apply threat lock to the bolts bolting back up to the tail housing. This took me a total of 4 hours to install all by myself. Once you have finished enjoy :) the drive shaft will be supplied with instructions as to how many foot pounds of torque should be applied to re-installation. Best of luck. People. Why upgrade you say well let's see. To prevent twisting a shaft as I managed to do so drag racing. A Noticeable increase in mpg as well.

  Much better than stock

  I purchased this drive shaft after much research about the benefits of reducing rotational mass. Very high quality and about 20lbs lighter. Had a race shop install it and check it on the dyno for vibration. No increased noise or vibration. After this drive shaft, forged rims and light weight exhaust; the car feels quicker. Very happy

  Installed within 2 hours

  I noticed no vibrations like some people have with other shafts, we did have to install the pinion flange and set the preload. Overall it was a fairly easy job with a experienced mechanic, I would not advise installing this without a lift, have a professional install it, because if you screw up the pinion flange, its your fault. on the road, I can definitely tell the car accelerates faster feels like it has lower gears, off the line very noticeable very responsive.

  Very nice piece!!

  The drive shaft is a very nice piece. Well built and best of all no vibration in a 2011 5.0 auto car. I did not see any performance gain but it is money well spend for a lighter more durable DS. America Muscle was very good to deal with. I had the DS 2 days after ordering it.

  Driveshaft Installed

  I had my driveshaft installed in conjuction with a dual clutch, 3.73 rear gears, and FRPP finned axle cover. Once break in period is over I'm sure she'll be a monster at the track.

  Great Bolt On!

  This DS is a great product, it took me about 4 hours to install, and I have average mechanical skill. The only issue was, while the suspension is "unloaded" my factory resonators touched just slightly. However, once the suspension is loaded "on the ground" it cleared just fine. Also, catbacks would eleminate this problem as well. But something to keep in mind. Performance is good, the motor rev's faster now. Plus it shaved off 20+ pounds! Bottom line is it's definatley worth the money! Buy it!

  Noticeable Different but Not Balanced!!

  I paid to take off the stock DS and put on this one-piece one. Then I had a vibration and it hit on the exhaust over one of the unavoidable big bumps on my way to work. I think the diameter of the one-piece is a little bigger than it should be to get the bump, which possibly could be the reason this particular one has been discontinued from AM. So since the vibration didn't suit me, I paid to swap it out for the stock again. But just to cure my curiosity, I took the one-piece to a machine shop to see if it was unbalanced and unbelievably IT WAS and I have the receipt and the new weight on the one-piece to prove it!!!!! ***It was not properly balanced right from the Driveshaft Shop and AM!*** I only ran it for 4,887 miles (I have my service records for this mileage as well)!!! So not only was the product out of balance from the time of my purchase but I've spent (I'm going to do it myself next time) $100 each time at my shop to get the thing put on and taken off. But of course, as any Mustang Owner would, I feel a duty to science to put the one-piece back on again to feel what a properly balanced DS feels like! Most people would say the difference is negligible and going from stock to the one-piece and I'd day they are right (although I could tell a difference in how snappy the car was) but going from the one-piece BACK to the stock was huge! The car is so sluggish with the stock compared to the one-piece and I need to get it back on!!! If you have some stupid money laying around, I'd say buy one. But with my experience, I'd have it balanced before you put it on just to be sure!!!! Otherwise I think it was a good purchase to give my car a bit more snap... even if it does hit occasionally on the exhaust.

  Heck yeah! No more clunk!

  This drive shaft remedied all the "clunkiness" during shifting that is present with the factor two-piece. I am very pleased with this purchase!

  So smooth....

  Never mind the increased acceleration, never mind the piece of mind from durability provided by this shaft, never mind the allure of lower ET's...do it for "the smooth". It's difficult to describe in words how much better the drivetrain "feels" after installing this drive shaft. (manual tranny) It's much more snappy, tight, responsive, and smooooooth. The slack, slop, and clunk is GONE. No vibrations. Extremely happy with this driveshaft.

  very light driveshaft

  i purchased this drive shaft mostly because the stock drive shaft would snap in half at my power level. it is very light weight and solid as well. As stated in other reviews, this is something a shop should install, unless you have access to a impact wrench with VERY high torque capabilities (at least 700+ ft lbs) and a 27mm impact socket, torque wrench capable of 140ft lbs. if you do not have the above and some mechanical know how, this is best left to a pro.

  A must have especially for 2012 mustang!

  Guys if the question is, is it worth spending the money on the product the answer is YES! Huge difference in throttle response and is a super easy install. I have the eibach sport line springs and the drop is 1.3" In front and 2.0" in the rear and it works great no additional mods needed even putting suspension under load, pinion angle is still within specs. make sure you count the amount of threads on nut before removing pinion flange bolt or just torque to 140' pounds. Again works great no vibration or hum, oh' and be sure to seat the pinion flange nut with a ratchet not an impact gun (impact gun is only to aid in removal of nut).

  you will notice a difference

  First thing you will find in your shipment is one small sheet of instructions that don't tell you much of anything , that you torque the new bolts to 76 ft/lbs I installed this with stock susp do not remove the paper covering the new driveshaft!!!. you need the following tools 10mm socket, 12 mm 12 pt socket. 13mm socket with a swivel 27mm (1" 1/16" ) socket and a torque wrench capable of 140 ft/lbs and 2 2x4 's about a foot long and tall jack stands (6 ton) and a small hammer (brass is nice) it's easier with two people also. first jack the car up and get it ask high up as you can run the stands to full up!! take out the original drive shaft ends loosen first rear is a 10mm front a 12mm 12pt then a 13 mm with a swivel to take loose the carrier bearing do the drivers side bolt first!! then slide the old unit out the back. set the e-brake and remove the pinion flange plate with the 27mm or 1" 1/16" socket , then tap the flange off. Grease the seal surface and and tap the new flange on the pinion and replace the pinion nut and torque to 140 ft /lbs. next is the hard part getting the new shaft in. don't take the paper cover off of it you will need to shove the 2x4's between the exhaust and the floor pan to gain room or drop the exhaust down the shaft goes in from the rear with the bellows at the rear ( i did this by myself extra hands is s huge help) it rubs everywhere as its going in ( had to use my feet to push it thru pulling on the swaybar) once it's in the tunnel put your bolts in using loctite and a 12mm 12pt socket and torque them to 76 ft/lbs then remove the paper cover it took me 1.5 hrs to install in the driveway by myself. I noticed just backing the car up a difference and it's so smooth and less pedal on the gas too.

  Way better than the stock clunker!

  The car responds faster and no more of the clanking noise from the stock DS. Install was pretty easy, I didn't have to relocate the e brake bracket thee was plenty of room with my 1.5" drop.
