02 7.3 milage

How much better milage would i get if i switched out my 4.10 gears for 3.73s? I have a dually and i use it to tow lots but i never halfto use the first two gears anyway.

I was recently wondering the opposite.
If I traded someone for their 4.10s what the trade off in power vs mpg would be.
So bump for you because I'm curious too.

PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.

Depends on what's going on tire wise. Larger tires do better with lower gears. Stock tires would be great with 3.73.

There shouldn't be a difference in the gears between dwr and swr. Axles and hubs, sure, but not gears.

What?? Most duallys came with 4.10s. I think 3.73s were an option on them. The SRWs came with 3.73s.

i did a lot of looking around for gears and i could be wrong but ford told me they werent interchangeable. my axle is a dana 80 but that wasnt good enuf. i had to get the number off the tag in the back. i just have 265s on and that already takes spacers.

Didn't even think about it being a larger axle. Let me go beat my head against a wall for a little bit.

In reference to changing gears. Not the value of the gear set. Deere straightened me up real quick.

Gear Vendors are pretty awesome. My Grandpa has had one connected to his '65 Dodge, 440, manual for as long as I can recall. The engine has been rebuilt twice, tranny once, in that period, and it's still plugging along. He drives like a grandpa, but we've had enough weight in the bed that the front end has lifted off the ground. I'm not kidding, steering was completed with full lock and brake pressure. His thought process was that if the truck moved, it wasn't too heavy. I can't knock it, as he's made it work for decades. The OD unit has held up all the while.
