I have an 2002 Z28, A4 that came with stock 2.73's. What came from the factory, an aluminum or steel driveshaft?

I need to be sure, I thought they were all supposed to be aluminum on Ls1's, except for verts, but the dealer insists it came from the factory with a steel one. (I had it in for warranty work last week, then went to install a torque arm this weekend and came across the steel driveshaft.)

i seem to remember hearing that the 2.73 equipped cars did indeed come with a steel DS.

 

My car came with 2.73's and the steel driveshaft. The 3.23 A4's and M6's have the alum.

 

I concur .

I'm not too concerned about the steel driveshaft. IMO, it's probably stronger than the aluminum one, and I doubt that the weight difference is all that much?

 

if its the same driveshaft that was used on the lt1's then there is a big weight difference and you can multiply the weight by 3 since its rotating weight.

i switched to an aluminum driveshaft because my steel one had vibration problems and the ls1 driveshaft was an easy pick up
