      Faster Quarters. Shed up to 29 pounds of rotating mass and shave up to 0.2 seconds off your quarter mile time with this SR Performance Aluminum One Piece Driveshaft.

      Made in the USA. Unlike other aftermarket driveshafts, every part of this driveshaft is made in the USA to ensure the highest level of performance.

      Application. This SR Performance Aluminum One Piece Driveshaft has been designed for the 1999 and 2001 manual transmission SVT Cobra Mustangs that require a 44.5" long driveshaft.

        Much needed

        Was a pain to remove 20 year old driveline bolts. But this driveshaft cured all vibrations, squeaks, and rattles.

        5 1999 Cobra - JoeTerps Installation Time: Shop Install Installation Cost: $100-$250

        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!

        5 2001 Cobra - Tim Installation Time: Afternoon

        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.

        Very light looks great

        Cuts down on vibrations acceleration is faster a little spendy but every bit of edge helps

        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

        5 2000 V6 - 2PonyMan Installation Time: Less than 1 Hour

        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.
