Towing with a 3.73 F250 6.2L, will a 4.30 axle help ??

Hey guys....... I have a 2011 F250 Crew Cab SB, 4WD Lariat with 6.2L and 3.73 E-locker. Running 5-Star tuner on it, helps with the throttle-lag and gets true WOT when you put the pedal down. Also...

A 4.30 axle will not give you more horsepower! Even with the 4.30 you will still have to wind your engine into 5000 rpm territory as you do with the 3.73 to pull the same hill with the same trailer at the same speed.


Um.......no!


All other factors the same a 4.30 ratio truck will out pull a 3.73 ratio truck on hills and high headwinds.

I guess the 1st factor to consider is will it pull $2500.00 better on a truck with a 6 speed transmission?
