Aluminum Driveshafts - Who Has One and How Did You Make It? December 14, 2017, 04:33:35 PM We have tossed this topic around a bit on here and I wanted to put together a thread with aluminum driveshaft in the title as well as link some of the better threads on the subject within the body. I would also like for anyone (Vinnie, cough, cough) to post up what they used and where they had the DS fabricated or shortened (you don't lengthen one) and their results.Threadshttp://www.foxtbirdcougarforums.com/showthread.php?40545http://www.foxtbirdcougarforums.com/showthread.php?31374http://www.foxtbirdcougarforums.com/showthread.php?34196http://www.foxtbirdcougarforums.com/showthread.php?19231Driveshaft ShopsPerformance Driveline, Oklahoma City (Not finding them listed any longer, maybe Vinnie can update)Blumenthals Manufacturing, Oklahoma CityDrive Train Specialists, Oklahoma CityDrive Shafts, Inc., Tulsa, OKInland Truck Parts, Tulsa, OKAction Machine, South Bend, INAnyhow one clear solution is the 1995 - 2010 police interceptor packaged Crown Victoria which comes factory with an aluminum drive shaft. These can be found at salvage yards for around $75 to $100. So you will need to supply the Crown Vic drive shaft, the input yolk to the trans in your car, the rear flat flange that bolts to the flange on the pinion of the rear end, and the drive shaft shop will provide the adapter u-joints. The Vic drive shaft will need to be shortened, the correct u-joints installed, and the assembly balanced so plan on another $120 or so for that work. So all in you might have $220 but that is cheaper than having one built. As Vinnie and a few others can attest to it takes care of the typical issues (mostly critical speed) with numerically higher rear end gears and steel drive shafts.Feel free to tack on any other shops or other vehicles that have aluminum drive shafts that can be used to make one for our cars.
