Aluminum Driveshaft Y/N


Is it worth putting an aluminum driveshaft in my 95 Mustang GT? Its a heavy car and shedding 20lbs off it couldnt hurt but is it a big upgrade and improvement for the money?

If you're doing it for the 9lb (not 20) weight saving alone, don't bother. You only need an aluminium driveshaft if you swap in steeper rear axle gears.
The reason is that the steeper gears lower the road speed at which the driveshaft reaches its critical speed (where harmonic vibration begins to occur). A lighter driveshaft will have a higher critical speed so you can reach a higher road speed before it starts to vibrate.

Not to invade the thread or anything but is it bad to have 373 gears and the stock driveshaft ?

Good mod, but there's better ones to do beforehand.

Alum. DS is kinda like pulleys. Slight difference, but when you put all these mods together, they can add up to some good weight savings / hp.

Also, when your under there, you can remove the huge hunk of metal under the rear end. Its very heavy, and just there to cut down on NVH. You dont need it at all. Its probably 20-30lbs.

Yes. The higher ratio axle gear will increase the driveshaft speed at any given road speed so yes, a lighter driveshaft would be beneficial.

That "dogbone" weighs 9lb and you can indeed remove it without issue, but make sure that you leave the pinion snubber and bracket in place.
