… or lack thereof compared to 2023 MY.

I’ve noticed the 3.31 rear axle is only an option for the 5.0 and not for 3.5 EB for 2024 contrary to the 2023 MY. Looks like 5.0s cannot have the 3.55 either. Can anyone provide the rational or benefit for this?

When considering the 2023s, I wanted the 3.5 EB 4x4 Lariat with the 3.31 axle. The 3.5 EB has more than enough torque to tow with a 3.31. I desire memory seats which pushes me into a Lariat and a HUD which means a 2024. In the 2024 MY, the 3.31 is not an EB option and I am forced to include the tow/haul package which I do not feel I need (nor a power open/close tailgate). I only tow once or twice a year and never above 4,000 pounds. For reference, I compared my current truck to the F150 Lariat below.

Your insights into this matter would be greatly appreciated especially if I am confused on some particulars. I like the extra torque of the turbo as it moves the truck effortlessly. Is it still worth it for me to get the EB in 2024 with the tow/haul package? I can’t tell from the website nor the owner’s manual what that really provides me.

what is your main reason for needing 3.31 over the 3.55? if for gas saving the difference is very small and not worth the headache. as for the power tailgate I have found that to be a once you have it you won't want to go back thing and why I made sure my 24 order had it. the hud is definitely a fun thing to have so far.

It is not that I need a 3.31 but I don't need the extra towing capacity and not sure what else comes with it. The 2023 3.5 EBs I drove had 3.31 rear ends. Slightly better gas mileage is a benefit as I take many cross-country trips. I'm more curious as to why would Ford make this change and the benefits or considerations. Is it more than just the listed trailer brake controller and upgraded bumper? Are the brakes the same, does the transmission get more cooling capacity? This forum has been my best source of knowledge. I want to make sure I understand the details and eliminate surprises. Your opinions and experiences are appreciated. Thanks.

I do not know, but my guess' are;

1. emissions, and likely the city driving area. The 3.55 will take less work for the engine and produce less emission from a stop and go perspective, and that sub 50mph. The turbo engine really like to chug fuel if you ever get into just the littlest amount of boost.

or

2. Consumer 'popular' choice. Majority of orders for XYZ always select 3.55, not 3.31 so lets remove that option. This will reduce their options catalog, which means less paper work, less management, less overhead costs to Ford basically

or

3. Supply chain, maybe they are having trouble getting enough parts, so they limited where they could be ordered to manage that...

or

4. There is some little snake in the options dept. who really likes to make stupid changes and limit consumer from getting what they really want, so it was remove to just to spite us

On the plus side, to get your truck from 3.55 back to a final drive of ~3.31 you can upgrade from 33" tires to 35" tires and your truck will be right back running like it would if it had 3.31, only loss here is the tires will likely be heavier, and you'll change the vacuum dynamics under the truck.....so your fuel economy will still likely go down.

I think they try and get the gears optimized for each engine that help the CAFE #’s globally in todays day and age. A tall gear on a boosted engine is fun but can also harm city MPG #’s as boost builds against that gear. To be honest you won’t notice much difference between a 3.31 and 3.55 in power or efficiency. It’s decimal points and not tenths, likely hundredths.

If you like the 3.5 EcoBoost get it with a 3.55. I would not sacrifice the engine you want for a slight alteration in numerical gear. I’m on the other side of the coin, I love the N/A V8 powerband. If I am putting around its soft, but power comes on hard if I give it any pedal over halfway point. For me that’s a good natural balance for a daily driver. Many like the grunt off idle of the EB, and you aren’t getting that fast spool/surge of TQ with a 2.7 or 5.0. The 3.5 almost feels like a little diesel, but a diesel with follow up that doesn’t fall on its face. It’s a good package 3.31 or 3.55 be damned.

I may be getting confused with the details. Does the MY 2024 with 3.5 EB have a 10,400 or 13,100 maximum tow weight? The 2024 towing guide list 10,400 then 13,100 with the Tow/Haul Package (53T).

... and the Feb 16 Job 2 Order Sheet doesn't make axle ratios any clearer. It lists the 3.31 as an option then shows two different 3.55, the XL9 and XL5. Thanks again for the help and comments.

Chip at Granger Ford went through the build with me and confirmed that 3.55 Electronic- Locking rear axle is the one I would get, not the one on Ford.com marked as "with Tow Haul". Whether that is 10,400 or 13,100 for tow weight is not a concern because I do not tow that much anyway.

Thanks for you comments that the 3.55 axle will not make a significant difference in the gas mileage and you experiences with the 5.0 and 3.5. I hope to place my order in the next two weeks.
