If anything id go 4:10’s. but 3:73 is a pretty good ratio. With stock tires anyways

I found that the 3.0 is not responsive to most "reasonable" attempts to modify. Perhaps, however, an Efan, a K&N filter, and some sort of dual exhaust might help to increase mileage.. Perhaps.
There's a few other tricks. Run on all synthetic oil. Replace all the spark plug wires. Degunk the engine.

Maybe you do not need to lower the ride to improve handling. Maybe stiffer sway bars would be all you need.
This should help.I'll be sure to do some math to see exactly what rpms I would be sitting around given my tire selection and a few other things.
I would like to lower the vehicle overall a few inches, if not for the lower center of gravity, but also for the ease of taking things in and out of the bed.
I'm reading mixed reports on how minor 2-3 inch drops affect fuel economy overall, but if it helps it helps.
Probably won't be a huge difference.. but it would make some difference. When I bought my 5k lb pedestrian smashing bronco it got 23mpg.. lifting it 2", adding 100lbs of rotating mass, increasing tire height by 3" and width by 1.5" only dragged it down to 21mpg. More rolling resistance too as I went from an all-season to a R/T tread pattern AND different wheels with enough offset to have the tires poke out to the edge of the tread would further decrease any amount of aerodynamics it had..
I would agree with @Blmpkn. There may be some gains in mileage, but not enough to make the cost worth the while. That 3.0 v6 will still yield 20 mpg no matter what you do.
Then again, it's your truck. Do whatever you want. Enjoy it!
Indeed! I get about 19-20 in the city and maybe 21-22 hwy, slightly better than average for a reg cab with a 419 axle.I'm not expecting huge overall leaps and bounds in fuel economy, like you've mentioned before, it all comes down to it being a fun project for me.
What I will say however, is the truck is already achieving a little over it's EPA estimate with simply some thinner winter tires, and a bed cap. At speeds greater than 65 MPH for prolonged distances. Getting 21 MPG over 550KMS with a high cruising speed, all with an additional 600 ish pounds of cargo and passenger is quite impressive.
It's important to note too that a jump from 21-23 MPG reflects an 8% boost in fuel economy. That's huge savings over a year, and a vehicle's lifetime.

I think these trucks are actually capable of better mileage than most give them credit for, the trouble is that they're of course trucks after all! Most folks have 4WD, and larger tires to do their offroad business, so I get the cynicism, but I think this little guy can surprise.
My very very lofty goal with all this is to get this truck to do 30 MPG recorded, with some basic ecomods, and hypermiler driving. (not driving 90 MPH at least lol)
