If you drive under 75 I would go 4.56s, or if you ever tow. 4.10s are going to put you back to less gear than you had stock. If 3.73s worked for you, then go 4.10s. Otherwise, for more power and vroom vroom, go 4.56
maybe if you didnt drive so damn fast, a tank of gas would last you a week!! well, you turn 2K rpms at 80mph now. with 4.88's you will turn 2K at 60mph. if you got 4.10's you would turn about 2300 at 80mph. you cant have both low end torque and high speed driving without alot of rpms. you need to choose what you want. i would say 4.56 for a compromise now, but you should think into the future some. are you going to be driving the same commute for the next several years?
It's all about putting the truck back into factory specs. Regearing is done to make the truck and drivetrain think it is still rolling the old R&P. this can be done by a simple math formula that I have listed countless times... Maybe it'll stick this time: (New Tires DIVIDED BY Old Tire) TIMES Original R&P = New R&P Example of my old truck: It was a 3.55 w/ 255/65/17 from the factory. I went to 35's. (35/30)*3.55=4.14 so 4.10 would put me back into spec. However, I wanted to go to a 3.73 factory setup. So... (35/30)*3.73=4.35 so I put in a 4.30 and my truck was great. Was getting 500+ miles out my tank when I didn't city much, and 475+ when I sat in drive thru. 4.56 will eat your tank up. But I'll prolly be the only one leaning AGAINST 4.56
This is stupid. Speeding is only good over long distance, like 800+ mile trips. If you drove 65 tops, maybe 70 you would see your tank improve immensely.
