Is an aluminum driveshaft worth it?

[Engel]

Did anyone have an aluminum driveshaft that fixed driveline vibration at high speeds? Is the 200$ worth it? What improvement did you notice?

I have not had any probs with vibration in the drive line but many others have and they say the Aluminum ds took care of the prob.

My stock driveshaft was done after only 9000 miles. I had violent vibration. The aluminum one obviously fixed that plus took off some weight. It's been on the car for 10 years now.

go for it, it fixed my problems, and takes off 14lbs. it also relieves stress off of you drivetrain(less rotating mass).

same here, but I see their cost has gone up quite a bit.

I'm guessing it deforms from hard launching?

Nah!. the needle bearings in the universal joints go bad causing the vibration.

alright thanks for the responses

I hate mine!!! It rubs on the E-brake bracket even after i grinded it down. I sold mine for 100.00 with 200 miles on it it looked sweet but i like to be able to put people in the back without rubbing the hell out of it/

My stock D/S and my alum were teh same size. Mine was actually hitting my ebrake cables (just secured them out of the way last week)... I also had to bend the ebrake bracket back up too.

I had the same problem in my previous car(rubbing) but that was it. I took care of that and never looked back. I have one ready to go on my car but don't want to put it on just yet.

An aluminum DS cured my high speed vibration problem. I chalked it up to new u-joints though which can be had for like 8 bucks each. It's good to loose rotational mass weight though. On top of that it comes new with ujoints and balanced.

As for clearance issuse I had the ebrake bracket thing too, I grinded some off of it. "Seems" ok now.

I swapped my gears for 373's and got huge vibration after that. Put in an FMS aluminum driveshaft and fixed the vibration right up! Of course, now I have the EBrake cable issue. I have to fix that one.

Back from the deeeeeaaaaaaaaad!

Looking into getting an aluminum driveshaft since I'm gonna change the clutch and its gonna come off anyway... got a question about this rubbing though. Does the rubbing occur on the bracket right underneath the ebrake only? Anywhere else? Also, just to clarify, the FRPP aluminum driveshaft is a 3.5" diameter while the stock 5.0 and awd aerostar are both 3.0" diameter, correct? Does the difference in diameter benefit either side?

I replied to this thread in 2005 and now again in 2012.

It did rub the Ebrake on mine only. It went away after time, probably grind itself down so it didn't touch any longer. Don't think the thicker diameter does anything else other than rub on stuff. The weight difference is noticeable.

In 2005 it was on the car 10 years, now its 17 years.

I don't have any rubbing on the aluminum driveshaft on my Cobra clone. However, when I installed the driveshaft I made sure to bend the parking brake bracket up again - it seems to bend over time. Only had the driveshaft on there for a couple of years tho.
