Default rear axle

I was talking to a guy that works with gm and he told me that the 02 z28 does not come with the 2.73 gears. It is either 3.08, 3.23, or 3.42 depending on my tranny type of a4 or m6. Any1 know if this is true? <img src="images/icons/confused.gif" border="0">

I just checked it on GM's website.

It does not mention the 2.73 gear at all.

3.08 or 3.23 for automatics
3.42 for 6 speeds.

Do yourself a favor and never talk to that guy again. NO 4th gen comes with 3.08 gears period. If it's an A4 it's either 2.73 or 3.23 depending on what RPO code you have. I think GU8 is 3.23. All M6s come with 3.42s.

Oh, I see where the confusion is coming from on the GM site. You get 3.08 gears in the V6 A4.

Edit: 2.73 is standard for A4s. This has ALWAYS been the case. However, I don't see it on the site either. But I know they didn't change it for one year, and the last year at that.

2.73 is standard. 3.23 is the "performance axle" and is available at an added $$$.

I fully understand that, but then again, every gm site i go to it says nothing about the 2.73 gears whatsoever being in the 02 model. it only shows the 3.08, 3.23, and the 3.42. ill guess ill find out when we jack up the car tomorrow! but when you get the specs on the 01 it does mention the 2.73s.

Our boys are right...

3.8 is a V6 gear.

2.73's are (GU2) are standard in A4 F-Body.
