Gearing plays a HUGE part in the mileage and the application of power...
many off roaders will regear a vehicle to regain the power lost with bigger tires/wheels -
but running 4:10 or lower (4:56,etc...) will really kill your highway mileage if you try to
run 65mph - you end up running 2k-3k rpm to try and maintain your speed.
running a 3:73 will give you much better highway mileage but you will suffer in power
situations since your multiplying less torque to the axles. My wifes Expedition is great on
the highway running 3:73s but can't outrun a Yugo from the stoplight...
yes being shaped like a box with a big upright windshied doesn't help
(I should know - just a smaller box), but the gearing and tire/wheel size is such a
big factor - more than most people realize until after they get bigger tires/wheels.
I am planning more lift and bigger tires/wheels in the spring and I know that
I need to add in another grand to cover installing new gears (I am not into the 'look'
I expect the vehicle to perform offroad...)
The difference between Genius and Stupidity?
Genius has limits...
