    • When I compared this to the stock driveshaft the stock came in at 20.4 and this one came in at 13.2. Hope that helps!

      Good weight savings

      My 01 Cobra, with just 49k on the clock, had a bad 3rd gear synchro, likely caused by someone putting something other than Tremec's recommended fluid in the tranny. So instead of repairing the existing transmission I opted for a Promotion PMP3650HD. With that on order I figured I would take the opportunity to upgrade the drive shaft and hopefully quell some of the drivetrain vibrations these Cobras are known for. The driveshaft arrived as expected and was packed very well. I took the time to weigh the old vs the new as well as take some quick measurements. The old driveshaft came in at just about 20.4 lbs with the new aluminum twist stick tipping the scales at about 13.2 lbs. Not a bad weight savings but I think I made up for it with my holiday binge eating. I did notice that the new driveshaft is roughly 1.75 inches shorter than the old but penetration into the output housing of the 3650 was more than enough to curb any concerns I might have had before installation. Out on the road the difference is significant, with the driveline vibrations falling off considerably. The car seems to accelerate with a bit more fervor, but since I replaced the clutch with a spec stage 3 complete with aluminum flywheel and a brand new gearbox, I'm guessing the trio contributed in some way to the improvements in drivability. Overall, I feel like it was a worthy investment and I would recommend it to anyone undertaking a similar project.

      This product has great features

      So the reason I got this product for my 2001 mustang cobra is that I put 410 gears in and I got a vibration around 130 so I got this drive shaft to stop the vibration it is a lot lighter then the stock one 10/10 on the drive shaft

      2001 cobra convertible

      Installation was easy an straight forward. This combined with eiback pro sport kit and bbk cai helped me achive 29.9 mpg over a 2760 mi cross country kit and stopped all my vibration. Great buy condiering I could have bought a cheaper one and have to get it cut down welded and rebalanced. A lot les hassle and perfect fitment. Thanks A.M.

      This thing is crazy light!

      This driveshaft is absolutely a stunning piece of work; multiple people looked at it and went "I wish I could weld like that!" The driveshaft is very well balanced and the weight of this thing is a huge difference from the stock lump of metal. After the install the car seems much happier and it seems to have cut down drastically on the vibrations that cobras are very prone to. I was a bit concerned that the yoke is about a full inch shorter then the stock one but there is enough of it that does go into the back of the transmission that it alleviated my fears. Install took roughly 25 minutes with a lift and a torque wrench. Overall I would say that I am very happy with my purchase. This is quite a bit more expensive then the FR driveshaft but after an examination I believe I got what I paid for in this.

      Show piece, too bad it's under the car...

      I'm (a mechanic I'm paying) is turning my 00 V6 into an 01 Cobra. So I really don't have anything to compare this to other than my stock V6 shaft. The new shaft is a lot lighter, and it's construction is very impressive. It's too bad this piece is underneath my car where no one will be able to see it at shows. It really is a masterpiece. The sticker it comes with to put in my build book is top notch also, I think the sticker was why the thing costs so much.

      01 cobra venom!

      Axle exchange alum drive shaft for the 01 cobra is a exact fit and looks great installed. Went in no problem and the car seems to fly through the gear changes smoother now. My Cobra with headers and 3:73 gears CAI and tune is now a beast on the street. Ford cut alot of corners when they made the 01 cobra and the heavy steel drive shaft is junk. THANK YOU AXLE EXCHANGE for being the only company to offer this light and strong perfect fit item. By the way the Ford motorsport drive shaft does NOT fit the 01 making Axle Exchange the only choice...

      99/01 Cobra Aluminum Driveshaft

      Great product. Quite pricy/pricey(sp?) for the amount you gain, but I wasn't expecting any more than I got. These driveshaft/yoke combinations are rare with the T45, so I had to go with the quality option I could find. Very well balanced at all speeds. Quite light for such strong construction. Engine seems much more snappy and seems to rev a bit quicker. Keep in mind that this is NOT a horsepower gain, but changes HOW your engine acts under load. A worthwhile investment, hands down.

      One Piece Of The Pie

      After 49,000 miles and several performance upgrades upping my RWHP to 450 I could feel my original clutch was getting a bit grabby and my T45 transmission was refusing to go into 1st and R without serious effort, and when it was in gear it whined and I'd swear a vibration was developing in the rear. So I sat down and put together a list of gear from an aluminum flywheel to the rear differential and everything between. A rebuilt and upgraded T45 with a 26 spline front shaft and Kevlar syncro's was first on the list, and The T45 Source took care of that for me. Royal purple fluid,l an aluminum flywheel, Ford Racing throw-out and pilot bearings, an OEM 2003-2004 Valeo Pressure plate to increase claiming force while retaining a light pedal for increased driveability, Mccleod 26 spline clutch disk, Steeda Tri-ax shifter, MMR clutch cable/quadrant, Ford Racing clutch release arm, and of course a Ford Racing Aluminum drive shaft. What? This review is for a that unnamed driveshaft.. Well, I bought the Ford Racing first because it had a name, a good one, and was less expensive. It didn't work out. So I ordered this one and was almost stunned by how nice looking it was and the attention to detail. "Very Nice" was my first and my lasting impression. Unfortunately it didn't fit! After discussion with the manufacturer we discovered it was the yoke. The new yoke was oversize, either by design or accident has not been determined. They recommended using our old yoke and they promptly paid my shop for their labour with this issue. Everything has been great since. Did the driveshaft improve performance? I doubt it. Probably no more than replacing my ujoints on the OEM driveshaft would have done. What it does, in combination with the aluminum flywheel.. is change the driving characteristics of the car. Better for track use, probably less so for street.

      Vibration Eliminator!!!

      My 99 Cobra had a drive-line vibration that got really bad over 90. This driveshaft eliminated it. It's smoother at all speeds now. Didn't really realize I had much of a vibration at other speeds until I installed this driveshaft. Smooth as silk now. Also, I live in Colorado so power is down a bit and I would have a little trouble accelerating up a steep hill in 5th. No problem now. Had my mechanic install it for 115. Also, the shaft is beautifully constructed! Worth the price!

      easy install

      I have 4.10 gears on my 99 Cobra and anything over 60 Mph I had a vibe from my stock driveshaft. I replaced it with this unit from AM and fitment was perfect. Vibes are gone, car feels lighter, more responsive, and drivetrain feels smoother. Received it packaged well and install was fine in 30 minutes. Best price I could find was through AM and customer service was very good.

      Easy upgrade

      Exact fit, solid looking driveshaft with less weight. Will be getting 4.10 gears and that will really make the most of the lighter rotating mass. Some heat and air impact gun made removal of the pinion flange bolts a breeze. I had drained the trans for a fluid change, which made for a neat and quick change.

      T56 swap made easy

      So I did a t56 6 speed swap in my 2004 gt. My t56 was the cobra r spec with the 31 spline so it was a direct drop in into a 2004 Mustang GT with solid rear Axel. So if you are looking to do a six speed swap the length is right no spacers needed you only need to change to a 26 spline slip yoke if you want to use a terminator-spec trans
