F250 3.73 to 4.30 axle ratio
I have a 2017 F250 4x4 crew cab, 160" wheel base, 6.2l gas, 3.73 gear ratio. I am trying to see if having 4.30 axle ratio gears installed will make much difference regarding 5th wheel towing. I noti...

To those that think that runnng in a lower gear is the same as having a lower ratio, you really don't understand what is going on in a transmission and rear axle? If that was the case then the manuf. would just tell people to tow in "X" gear to tow X amount of weight. Unfortunately it do not work like that. I would much rather spend the money on gears and/or gas than get into a newer diesel!
How about explaining the difference to us?
To make it simple, changing the rear gear ratio to a lower (numerically higher) ratio also effectively changes the ratio of each gear in the transmission. It just like having a longer fulcrum and moving the pivot point. Each gear becomes more efficient. I'm not a teacher so maybe someone's else can explain in depth as a teacher would. I'm just going by common sense thinking! And knowing about physics.
