I went from 3.55's to 4.10's...
heres a conversion to see what you'd tach...
at 25MPH w/ 4.10's, its the same as going 29 w/ 3.55's
35/41
45/52
55/64
60/70
65/76
70/82
75/88
at 85MPH w/ the 4.10's I'm at 3000RPMs, and I have a pretty healty 360 in my
truck... and the 4.10's didnt affect the highway MPG more than 1MPG i dont
think....
I hope this helps your decision...
