can anyone explain to me the real difference between 4:10's
and 3:73 gears I am ordering (tonight) a 2007 F-250 5.4L
super cab 142" wheel base (short bed) single wheel 18" rims, lariat with everything but a moonroof and marker lights. I had to order this truck
because there is not one of these "fully loaded" trucks anywhere
east of the Mississippi river. I will be pulling a boat 6000lb's and plowing with 8' blizzard plow, and for those that will ask no not at the same time I am not real up on gearing, I know the 4:10's
are lower and better for the pull/push but is there a big enough difference? and are the 3:73's good enough for this? I know they get a little better gas milage. any help/thoughts would be appreciated.

Save the gear money and go with the V-10. It's a $600 option that you will be much happier with. 3.73s with the V-10 will do just fine for ya.

 

Get the DEISEL !!!!!!!!

 

i have 33" tall tires on my F150 5.4L 4x4 and just put 4.56's in the front and rear. Huge difference, I pull 5500lbs everyday and still get 15mpg city and 18mpg hwy. A big misnomer that many people believe is that the lower the rpm the better gas mileage you are getting. Wrong......the 5.4L makes peak torque in the middle rpm range. If your peak torque is around 2600 rpm, why would you want to tow with the motor at 1800rpm. I noticed a 4mpg increase on the interstate towing (lack of gear hunting, stays in OD.) and 2mpg interstate not towing. The motor is put into a better efficiency range with with the proper gear selection. However, I do agree to get the Deisel......It will pay for its initial cost, in fuel savings, nad longevity. Also, another reason the deisels tow so much better is that the motor is extremely heavy, which acts as a counter weight when you have heavy tongue loads. If you are going to pull 6k+, the tongue weight actually makes braking in the rain a little sketchy sometimes, and the ride is considerably more bouncy. Lastly, pushing a plow will be much harder on the front suspension of a gas truck compared to the deisel. The front end isnt built as heavy and the plow, especially an 8', is gonna work the gasoline truck suspension over. Save money in the long run and buy the deisel......just my opinion....
