ford f250 axles

sregdab

I'm buying an f250 extended cab fwd with the v10 and want to know if anyone could give me info between the 4.30 axle ratio w/ limited slip versus the 3.73 ratio w/ limited slip. I want to know if gas mileage is significantly different or fairly equal. I'm going to pull a boat that's about 5500 lbs. Any and all info between the two would be greatly appreciated. Thanks

Mileage should be at least 2 mpg better with the 3.73 on the highway. That truck is plenty powerfull enough to pull a 5500lb boat, go with the 3.73 unless you see 5th wheel trailers somewhere in your future.

YOU ARE GOING TO BE TOWING ALL THE TIME.

I tow 7500 lb camper about 5000 miles a year, no sweat. I tow at about 75 mph.

I have towed Mom's 9800 lb camper too. Still no problem, but you notice the difference. Had to keep it at about 70 mph to keep from working it too hard.

I like the extra dig out of the hole, Don't believe there will be that much diff in economy at cruising speeds ( I've seen a best of 14 on cruise control between 70-75 with a V10 crew cab)

And, lastly, if you ever go to bigger tires (like I did before I even got the truck home) the ratio will be effectively numerically lowered anyway.
