Default 01 M6 Z-28 doesn't have aluminum driveshaft?

My A4 98 had an aluminum driveshaft but after looking at my 01's it has rust on it like a regular driveshaft. I thought all 98-02 f-bodies came standard with an aluminum shaft? Am I mistaken? I noticed this yesterday while installing some LCA's on the car. Thanks!

If I'm not mistaken all 3.23 and 3.42 geared cars had the aluminum DS. The 2.73 cars had the steel one

Why in the heck does my 3.42 M6 Z-28 have a steel one then? My 98 was a 3.23 Auto and it had an aluminum DS. I checked with the previous owner and this car has never had it replaced. Strange.

From what I know i thought all the 01 and 02 M6's had an Alum DS, i don't know what my car's rear had stock though cause i have 4.10's now and thats the way it was when I bought it.

The steel driveshaft could have been used under a deviation at the plant.

That would be my guess...it isn't unheard of to have this happen. They probably just didn't have any aluminum driveshafts available that day, so they stuck a steel one in.

my car has a steel DS in it but tonight it is getting a Chromoly DS from Speed Inc. This thing is a lot beefier than the stock steel one.

Guess we all learned something, thanks for the info! I should've swapped the aluminum one out of my 98 into my 01, oh well.

Maybe it's something to do with the tires the car came with? Mine's a 2000 M6 Z28 that factory had those stupid 235/55/16's on it...with a 118 mph top speed limiter in the PCM (that I turned off sunday) and a steel driveshaft underneath it.

Either it was a factory goof or a previous owner swapped it out, I tend to think it was the former, rather then latter.

My 2001 M6 originally had the steel driveshaft, crappy 235 tires, and 118mph speed limiter (though it did get the 150 speedo). All of those deficiencies have been corrected.

The 235 Eagle GA was not Z-rated, while both of the 245 tires options (RSA and GC if I recall correctly) were.

I think that for M6 cars, only those with the Z-rated tires (and the higher speed limiter setting) got the aluminum DS.

I also think that all of the tire options for 2002 were Z-rated, so most likely all M6 cars from that year only got the aluminum DS.

Mine also got the 155 mph speedo...I don't think I'd have bought the car if it didn't have that.
