Not really at this point. I can just notice a significant power difference over my previous truck.
Dealers have no idea about gearing and the 6.2. I had to show my local dealer the numbers. I'm running under 1800 rpms at 60 with my tires. That is nothing, and by the response people give when 4.30's are mentioned, you'd assume I would be running at least 2500 rpms. Which would be true in the old manual 5 spd trucks.
Just last week I told one of my regular dump truck drivers about my new order and why I ordered a new one already. Gears is always my first reason. He tells me, like I hear locally all the time; his logger friends run 6.2's now and once they load up the 6.2 with gear and a equipment fuel tank, they can't stand the way the truck preforms(3.73's).

 

Congrats RD!!!!!!!

 

I know plenty of guy's that pull heavy trailers with the 3.73 gears and they love them. If 3.73 gears are so awful and useless why does ford make 99% of there 6.2's with the taller gears? I have the 4.30's and hate them. 10mpg all around and worse when towing. 4.30's don't equate to better mileage either! According to you if you get 4.30's you'll get better mileage and more power. I disagree you can't have it both ways.

 

1. Because it is the default order gearing and sales managers don't care.
2. Depending on your driving style and use, 4.30's will get better mpg and have more power in the 6.2.
There are many threads and other internet discussion/articles about the topic.
Since you hate them, maybe you could find someone to swap with in your area? I don't know what a dealer would charge and how quick they could get it done though. I guess it would be nice to know.

 

If you want 3.73's, drive down here to Tennessee and I'll swap them out for your 4.30's. I've got a 2016 with 9600 miles. Get here early in the morning and you can head home in the early afternoon.

 

I'm quite a distance from you. But thanks for the offer! I bought my truck with the 4.30's thinking me and the wife were going to upgrade to a big 5th wheel but plans changed. I just wish I could do better on mileage with these gears.

 

If your driving empty on the interstate all the time, I can understand your point. But my dad has 4.30's and gets better in town mpg than I do with the same size tires. I like the way his truck accelerates from a red light at light throttle vs mine as well. I do get 16-17 on the interstate empty though. His is around 15. Everyone's driving experience is a little different, so unless you drive the exact same route as someone else, it's hard to compare. But I'm guessing your right foot has a lot to do with your mileage. I know mine can vary about 4 mpg depending on my foot, but for the most part I've been getting 12-12.5 on my daily commute but have been able to achieve as high as mid 14's with a lot of discipline. My offer still stands if you decide to take a vacation this way. I'm willing to bet someone in your area will swap with you in a heartbeat with similar or less miles on their truck. Should not be a hard job to swap the axle assembles on trucks sitting side by side.

 

My truck has 3600 miles on it and I am averaging 12.8 mpg overall through all of those miles. Some are towing, some are empty, some are in town and some are on the highway.
If you are only getting 10mpg then I would say you probably have a heavy right foot because I get better than that when towing and I live in the rocky mountains.
I love my 4.30 rear end and have told my dealer they are short changing their customers by ordering their in stock trucks with the 3.73's.

 

Just picked mine up yesterday - F250 XL FX4, 6.2L, 4.30s, CCLB. I can definitely tell a big difference over a 16 6.2 with 3.73. Power band feels a lot smoother around town, definitely don't have to push it nearly as hard to keep up with traffic.

Truck has right around 100 miles, getting about 12.5 average with 60/40 highway/city.

For what it's worth, it was turning 2500 RPM at 75 mph on mostly flat highway, getting about 15. I expect this might improve slightly over the first couple thousand miles.

Long story short, the updated 6.2 feels really great. It may just be the new car smell but the truck is much more enjoyable to drive normally than the 16, and the torque curve feels flatter even taking the lower gearing into account.

Merging on to the interstate at 75 from a standstill on a fairly short on-ramp is fairly effortless; none of the full throttle hard shifting drama at all.

Also noticed that at 75mph trans stays in 6th gear up to about a 3% grade, and only drops to 5th on longer 3-4% grades. I have no worries about pulling some of our heavier trailers at speed anywhere now.

Was worried it would be kind of a dog, but it has proven so far to handle every situation with no fuss or strain. Definitely very happy with this heavy service gasser so far.

 

I drove hard today on the back roads. I can really notice the power come on in the 3200-3800 rpm range now. On hard accel the new truck doesn't go all the way up to nearly redline to shift now. It is a power band that my '16 was missing.

 

With similar 2017 6.2 reports as your's starting to come in, even the 3.73 gears might now be a viable choice for many more people. Such a truck should certainly be more enjoyable to drive. The lower rpm torque band AND shorter 1st gear (at least in the F250 with the Torqshift-G) should really wake up a 3.73 equipped truck. However, I do think that the 4.30 gears, such as you have, would still be a wise choice for towing 9000+ (give or take depending on performance preferences) up steep grades and in high altitude areas.
