eco boost info

Those of you that tow with F-150 Eco-boost, which rear end gears are you using? Seems to me that 3:31s are alittle small and the dealer wants to sell them to me. I researched it on the Ford website but still am sceptical of the #s. I use a Tundra 5.7l/4:30 gears now and if you ever towed with one you would see why I'm not sure so Looking for input from you experienced F 150 users. ( towing 5000lb unit)

Tx in advance.

First off:

to the Forum!!

I do not have a F-150 so cannot directly address your question other than to say remember while a higher numerical rear gear is always better for towing, you need to keep in mind the overall final drive ratio will also be controlled by the tire size and transmission gear ratios. So comparison from one brand to another may be misleading.

Many years ago Dodge (well it was technically Mercedes at the time) changed the transmission gear ratios in the manual transmissions without telling anyone. It made a huge difference in final drive ratio and made it better to have a lower numerical rear end.

I sure wouldn't do it, unless all of your towing is for very short trips, and not that often.
Can you even get the towing package with a rear ratio that low?

Tx for the info, that is why I"m looking for real time towing feedback. The dealer would not let me take one home to do my own testing and I do not want to get stuck, I love my Tundra!

Here's my $0.02

Been a Toyota guy all my life.......many many Toyotas in the past. Traded my 5.7 Crewmax 4x4 for wife's Lexus. Truck was annoying daily driver in DFW metroplex because it was built for towing.....period. Loved Toyota......never really happy with ride quality of the Tundra. Gas mileage sucked but I know it would tow anything. However, didn't have a travel trailer at the time.

Moving forward:

Never thought I would own a Ford until I drove the ecoboost and the back wheels broke loose when I hit the gas on the test drive. I bought the truck and had the dealership add all the aftermarket stuff......35" tires, etc.

As a daily driver, it's a real pleasure to drive. However, with the 35" tires, I have an appointment to get the 3.55 gears changed to the 4.10 gears next week. The gear change will bring it inline with the 3.73 performance and I am convinced it will be a towing monster........hate to say it, but I believe it will be better than the Tundra because the ecoboost Torque & responsiveness is insane compared to any V8 I've ever owned.

Bottom line: Ecoboost is the real deal. If I were doing it over, I would get the 3.73 rear end and the max tow package, no question. You will appreciate the increased payload even if you don't think you will need it. The 3.73 mileage will beat the Tundra mileage all day and the engine is so quiet and the ride quality is a dream. Never thought I would say any of that about a ford.....just the way it is.

FYI: If you are interested in learning about the Ford quality changes, research the CEO and his actions during the auto bailout days and you will understand this is not the ford of 5 years ago. I was scared to buy ford until I did all that is a different company now!!

Hope that helps.

Kinda my feelings also, lots of up hill here in NW Pa! From what I have been able to find, looks like I would have to special order the truck if I go that way.

The other thing I haven't been able to find out is just what does the "max tow " package come with other than the mirrors and more Bumper weight.

Ditto. It looks like Ford also offers a 4.10 final drive ratio for the Ecoboost, but with no increase in towing capacity. But imagine how that puppy would come off the line. But those might be a little rough on the fuel on highway fuel mileage.

3.73 & Max Tow No Regrets

We have the Ecoboost with the 3.73 and max tow package.

Frequently tow our 21FBRS TT (5K) or a 2-horse trailer with dressing room (7K).

Yes, overkill for both, though very nice to get up to cruise speed (55-65) with either trailer fully loaded. No worries.

The truck is a daily driver and gets 16-17 mpg stop and go. We have seen 16 mpg highway with the TT on flat land.

I have seen 28 mpg on highway empty (55 mph) and gentle on the pedal.

The lower rear axle ratio is not suitable for towing. Also, the power is there is you need it or decide to upgrade. You know you're going to get a bigger TT.
