Chep, My current truck is a F550 4x4 manual tranny.
this discussion has kinda come to an end. Sadly US Gear was sold to another co and they have dropped the Dual range from production.
I stumbled upon a used one the other day in an RV forum and bought it just for the ability to have spare parts should I ever need them.
there might be a few still out there on vendors shelves. it will just require a diligent search to find them
It would be wonderful if some other co would pick this up and begin marketing them again, but in the current economy its doubtful.

I drove my dads '39 convertible sedan a couple weekends ago and it sports an accessory "Columbia" two speed rear end. Its an overdrive unit as opposed to the old Model T "Ruckstell" which was an underdrive for climbing hills. It was cable actuated and worked great!

got a 2020 f250 lariat 4x4 10 speed automatic 7.3 new gas motor looking for the gear venders to see if they have come out with an over drive for this yet. I think that would be alot cheaper than the dual speed rearends mentioned earlier. Any suggestions?

But first, Welcome to FTE!
Second, your brand new 2020 F-250 with a TEN speed automatic transmission already has not just one, not just two, but THREE overdrive gears already built in!
- 10 Speed 10R140 TorqShift® Heavy Duty with SelectShift® (New for 2020)
- 1 -- 4.615
- 2 -- 2.919
- 3 -- 2.132
- 4 -- 1.773
- 5 -- 1.519
- 6 -- 1.277
- 7 -- 1.000
- 8 -- 0.851
- 9 -- 0.687
- 10- 0.632
- Reverse -- 4.695
Finally, you've posted in the 7.3L sub-forum. Which at a cursory glance might make sense, as you have a 7.3L... but yours is a brand new gas motor, and this subforum is for 20 year old diesel engines which just so happen to have the same displacement. I highly recommend you post in the 2017+ newer Super Duty sub forum , where you will find more kinship and relevant experience with similarly situated members having the same model and type of new truck that you have.

Welcome to the best Ford 7.3 Diesel forum on the planet, John.
With the ridiculous amount of ratios in your transmission, what makes you want more?
I have a Gear Vendors OD, just curious.

I can hit 10th just fine at 20k gross on the highway at 70 just fine. My 379 with the 18 speed and a .73 final ratio will also cruise the highway at 60mph loaded easy enough. I think the 10R140 has plenty of useful gears.

But maybe very usefull in an unloaded situation.
The ratio spacing seems too close 9th - 10th, but I assume thats engineering issues and not intentional.

Quoted from gear vendors own website;
"If you have a factory overdrive transmission and are thinking the Gear Vendors will get you better mileage when towing – we would not agree. It is false economy to think you can tow a heavy load with just 1/2 an engine revolution per driveshaft turn. Staying at 60mph and below are the best ways to save fuel and wear on your truck because the aero load of the typical trailer is 1/2 at 60 what is at 75mph. Factory overdrive + Gear Vendors is perfect for when the truck is not towing, but when you are towing the aerodynamics require horsepower. The UNDER/OVERDRIVE™ can be extremely beneficial and capable of delivering hundreds of thousands of miles within these limits."
