Mpgs diff between 3.73 and 410 gear?

[Schoust]

Hey Guy's looking at an 04.5 with a 4.10 gear and was wondering what the difference was in MPGs between that and I believe the other option was a 3.73? Could be wrong? The truck is a 3500 auto. Is there a performance gain with the steeper gear? My last truck had 3.55 just curious....

Faster off the line but milage will suffer a little.

Hey How hard is it to change to the 3.73??

Not cost effective however the 3.54 are!~

I have 4.10 gears and I run my Smarty with TNT on 9 24/7 and get depending on how i drive i can get between 20 and 22 mpg hand calculated. With mixed driving i get usually around 21.5 mpg.
