Difference between 4.10's 3.90's 3.73's
I am about to purchase some gears and want to ask some questions. Going from 3.42's to 4.10's what kind of Mpg loss am I looking at? Also how much ET difference would the 4.10's from say 3.73's make and also from 3.42's? Also to through another option in what about some 3.90's? I have got some numbers on the rpm increase from my stock 3.42's to 3.73's would be around 7% which cruising at 2000 rpm would bump up to 2140 and prob. be around 2300 with the 4.10's. Shoot my some opinions and yalls suggestions or knowledge on this.
