Whats the difference in the 392's and the other gear set?
I have the 3.21's and it's a bit sluggish off the line. 50% of the issue is most likely the computer and the Eco mode that the government likes to see but I am really kicking myself for not getting the 3.92's at time of order as it was only $50 more. They have 3.55's on some trims which I think would be perfect but not available on most Hemi trims. If you drive a lot of highway the 3.21's may be better but if not and tow definitely get the 3.92's. Look for trucks with the anti-spin differential as well. It can all be added/fixed later but will cost near $1k. Most people with 4WD add larger tires and a lift, they really recommend the 3.92's.
