Default 2008 Z51 rear axel ratios?

Anyone help me with this one?

Reading over the spec sheet on the 2008 in the section on transmissions & ratios is this, "Also new for ’08 models is the availability of the 2.73 performance axle ratio with the automatic transmission. It is included with the Z51 package."

Down further in the specification list the rear end ratio shown for the Z51 package is 3.42.

So, which is it?

Wayne, who is about to take the plunge!

Auto gets 2.73 final drive in the Z51. Manual gets the same 3.42 final drive but different tranny ratio's

3.42s for the manual, 2.73s for the A6 Z51.

It is both. If you get the 6 speed manual it is the 3.42. If you get the six speed automatic it is 2.73.

Thanks to all. The way it's written looked to me like it related to both the 6 speed & auto.

Doesn't matter now because the salesman that quoted me just emailed back that his computer left off about $1800 so I'm back to ordering and after reading about cross drilled brake rotors I'll do without the Z51.
