Std axle vs. perf axle
I assume the 3:15 performance axle improves acceleration somewhat. Is there a performance benefit to the 2:73 standard axle?

With the automatics, 2.73 is standard but the 3.15 is included with the Z51. If you get the standard suspension or the magnetic ride control F55 you can order the 3.15 for another $395.

I owned both and noticed a huge difference in the 3.15 for acceleration and just "fun to drive" factor. Owned the 2.73 first so didn't know what I was missing. Couldn't go back.
Small difference in MPG. 28 vs 26 Highway and 21 vs 19.5 combined.
And as far a resale??? Noone will say to you, "Man nice car, just wish it didn't have the perf. rear end!"
