Why?
Have you done the math?
Trans ratio gearing--4 speed----------6 speed
1st gear--------------3.06--------------4.03
2nd gear-------------1.63--------------2.36
3rd gear--------------1.00--------------1.53
4th gear---------------.70---------------1.15
5th gear-----------------------------------.85
6th gear-----------------------------------.67
Overall gear ratio - trans X rear=overall ratio
-------------------- 4 speed w/3.73-----------6 speed w/ 3.08
1st gear-----------------11.4-----------------------12.4
2nd gear-----------------6.1-------------------------7.26
3rd gear------------------3.7-------------------------4.7
4th gear------------------2.6-------------------------3.5
5th gear-----------------------------------------------2.6
6th gear-----------------------------------------------2.0
I guess it depends on what you want to do with the truck but it looks like 6 speed with 3.08 would be better than 4 speed with 3.73.
Hope my math is right and I didn't fat finger it to many times.
The 6 speed 3.08 actually looks similer to a 4 speed 4.10 after doing the math.
i'm sure your numbers are right, but i was basing it on real world experience. i have a friend who has a 2010 Z71 CC 4x4 with the 3.08 gears. he let me pull my trailer with it oneday to see how it drove. he doesn't use his truck for pulling like i do. needless to say his truck is a DOG compared to mine. your numbers might be on par but from my experience it just isn't the setup i would want for my uses.
