Aluminum driveshaft

[Ike83]

I'm runnin' an aluminum DS with 3:55s, and it's as smooth as a baby's bottom.

It is a little tighter around the ebrake and mufflers, but i've never had a cat-back that had any issues with the shaft and my ebrake (although it doesn't work) doesn't rub.

Like i was saying before though, i think any advantage that it might give you in weight savings is going to be lost because of its larger diameter. I can't think of the term for it but spinning objects with a larger diameter consume more energy than smaller objects. It's really only 5lbs or so lighter too so the biggest reason to get one is the vibration thing and the fact that they're much stronger. I've heard that the shaft itself will handle 1000ft/lb if you have the universals that'll take it.

You're probably thinking of MOI.

Nik,

I did it. I noticed nothing and I had 3.73:1, no dogbone, and a steel driveshaft.

It looks pretty though.

As for the guy that seen a 2.5-3.0 mph gain, there was other factors at play, not the driveshaft.

I gained 3 mph between two trips to the track and the only change I made was a 3G alternator.

The gain was not because of the alternator obviously.

Do not buy it expecting to notice anything.

Are these the aluminum drive shafts coming out of the vans or are you guys buying these new? I'm getting some serious wobble and its becoming apparent at lower and lower speeds, I think I'm gonna putt off the dogbone cause it looks loose.
