Im looking to replace my driveshaft with a rebuildable type, and looking for an aluminum driveshaft. I want beefier u-joints that I dont have to worry about breaking and lighter rotating mass to further lighten the seven. Ive only seen one place that sells them and its Horsepowerfreaks.com but they want close to 500 bucks for it. Anyone know where I could get an aluminum driveshaft cheaper without getting......shafted

well any drive shaft shop should be able to build you one but i dont know what they will charge i know my custom drive shaft fot my mazda ran me 425 with a costom pinion flange to go with it. mine isnt aluminum either

daaamn, so why custom? what did you need it to fit or what material is it made of? sounds expensive for non-aluminum.......<span style='font-size:8pt;line-height:100%'>carbonfiber???</span>

well it is made out of dom seamless tubing it had to be custom to do the TII trans to the first gen rear end with bigger u-joints and so on it is pretty light for being steel i also had a rear input flange done for the third member

so re-drilling the 3rd member and using the stock TII shaft wouldnt of worked? or changing the yokes on a first gen shaft? I've seen the TII tranny in a first gen a few times but didnt think it took that much trouble for the shaft to fit...................I said shaft...huh huh

no the TII shaft is longer than what i need and the rear yoke wouldnt bolt up even if would have drilled it the bolts would have been on the outside of the flange

If you don't want to have to worry about the driveshaft breaking, I wouldn't go with aluminium. Steel is far less brittle and resists torque better so you can afford to have a smaller dia. driveshaft, meaning centrifugal force. If you want to spend money go for a carbonfibre driveshaft.
