We are currently seeing the same power gains from the 15-18 5.0's we can pull 30hp and 32tq on 93 octane fuel!
I do see the option code 627 comes with the 3.73 and 9.75.
I know 410s which on in the raptor come with the 9.75.
Today at the ford dealer i did see 3.55 and 3.73 with the 9.75. But they were both 3.5ecoboost. All the 5.0 and 2.7 i saw today were 3.31 and 3.15 with the 8.8 and just a regular tow pacjage or no tow package.
4.10 was in the...6.2 raptor? 4.10 also came in the Tremor and it has a 9.75. These two trucks are the only trucks that came with 4.10 factory.
11-14 had 3.73 on max tow and 15 plus max tow is 3.55 isnt it? I didn't think you could get a 3.73 in a 15+?
This super 8.8 started when, 15? i forget. Is a 9.75 really needed over super 8.8?
So I'm curious then, do you know if your truck has the max payload package? LT tires from the factory would be the dead giveaway for the 627 option. I ask because thats the way from the spec sheet I can see the 9.75 is available with a 5.0 engine.My 2017 has 3.73s with a E locker. Its also a 5.0, 4x4 with a 9.75 rear end. 3.73s are rare on these trucks its seems. When I was shopping I found dozens with 3.55s then I found my truck which had everything I wanted option wise and low and behold it had 3.73 gears as well. I bought it on the spot and love it in all aspects. Sure the new ones are expensive but you get so much content and tech in the new trucks. I had a 2007 w a 5.4 that I bought new and traded it in on this 17. Light years apart. A decade makes a huge difference.

It's kind of driving me nuts! I look at every truck I work on, every new one dumped by transport and all 5.0 trucks seem to have an 8.8. All 3.5 EB trucks have a 9.75. The axle codes seem to denote gear ratio only, and I just can't find what dictates the ring gear size. Used to be easy. Big motor option got the bigger axle.
On the build sheet for 2018
4.10s are shown for the 17-18 raptor
Which is now a 3.5HO ecoboost
In 2015 you could not get the 3.73. It was not an option.
For 2018 F150 3.73s can be had in
2.7ecoboost
3.5ecoboost
5.0 v8
For a daily driver truck the super 8.8 will be fine. I would not option to get the super 8.8 as IMO the 9.75 is a proven solid strong axel that tends to last with little maintenance.
Super 8.8 is cost savings for ford over 9.75.
Do you happen to have the window sticker to that list all the options?My 2017 has 3.73s with a E locker. Its also a 5.0, 4x4 with a 9.75 rear end. 3.73s are rare on these trucks its seems.

I had no idea 4.10 could be on eco raptor, i thought 4.10 was done. The way I read your message was it sounded like you could order 4.10 on a "regular" truck.
Ok so I was right about 15+ not having 3.73. I think they limited it to 3.55 bc lighter truck did not need to gearing to perform the same as the previous steel bodies + fuel economy? I'm guessing 3.73 is back for 2018 bc 10 speed, so you can get as good or better fuel economy with that. if you have a 5.0 NA and towing, I would opt for 3.73, eco doesnt need that.
Yes the 9.75 has been proven. The super 8.8 has a much larger pinion and thicker ring gear than the old 8.8. Also the super 8.8 is lighter than 9.75 for fuel saving, that played a factor into Ford putting them in too.
Finally, if you are towing a lot and using bed a lot, do 15+ have HD payload? If you got HD paylod in a 11-14, it has 7 lugs, extra leaf, 3.73 and different rated tires. I believe its 8500lb payload in that year, i am not sure what 15+ can do, I imagine more.
