I know 3:55's are stock. Getting 25mpg on the interstate avg 22 town/hwy. Anyone know how gas mileage is going to be affected by moving to 4:10's? Daily driver so I can't have it hurt too bad... Also, everyone talks about 4:10's do 3:73's make no difference or what?

 

i was averaging 18/19 city on the 3.55's with my 4.10s im doing a average of high 17 low 18. So on conclusion, my guess is about a 1MPG difference. Also note its only a 300RPM difference. Hope that helps and no to 3.73s mach loves the gear look at our redline! i want 4.30s now.

 

yea to me 3.73 would not be worth it unless you have alot of power but 4.10s seem like they really help im getting mine hopefully in the next month
