2.7 Liter Ecoboost and 3.55 Rear ..5K Towing Capacity?

Page 18 of the Ford 2017 Trailer Tow Guide does NOT recommend towing with a 2.7L 4x2 SuperCrew with 3.55 (note the dashes in the boxes). 4x4 is limited to 7,600 lbs and only on the 145" wheel base version.

With a 3.73 rear axle that jumps to 8,100 lbs (either wheel base) but I would want the Trailer Tow Package and the 2.7L EcoBoost Payload Package.

The Trailer Package Includes:

• 4-pin/7-pin wiring harness
• Auxiliary transmission oil cooler
• Class IV trailer hitch receiver
• Pro Trailer Backup Assist
• Tailgate LED
• Smart Trailer Tow Connector
• Upgraded front stabilizer bar

I think you are linking to the 2017 towing guide. Here is the link to the 2018 Guide and it shows 7700 pounds for a 4X2, CC, 2.7 Ecoboost with 3.55...unless I am reading it wrong..

Concur on the trailer package.

One possible meaning of the "-" in the 2017 guide you link to is the 4X2, 2.7, 3.55, CC combo was not offered as an option in 2017. Otherwise the dashes don't make much sense. Think about it, look at the Table, a given configuration at XX,XXX GCWR can tow Y,YYY pounds but the same configuration at a GCWR of XX,XXX + 100 has a "-". Does this mean it is not recommended to tow anything? I suspect it means that combination was not offered that year.

I think a more probable interpretation is the combination of an F150, 4X2, CC, 2.7, 3.55 was not offered in 2017 hence the "-". In 2018 it was offered hence the 7700.

Very informative and comprehensive guide I might add.

One thing to be aware of and that is, if you lease the vehicle, the lease may exclude towing anything.

I beleive this is correct as well, since the 4x2 2.7 powered F150 with the 3.15 or 3.31 axle ratio is rated at 7600 towing/12,300 GCWR. It stands to reason that if 3.55 gears were available in the 4x2, it would be rated to tow more than the 3.15/3.31 rather than not rated to tow at all.

Op,
Not a owner of a 2.7EB but I recently rented one to drive from Houston to Dallas and back and was amazed by the power and fuel economy that truck made. I have no doubts that truck would be a strong pulling truck.

I would suspect based on ALL of the models listed in the guide. The dash in the space is a non optionable combo! IE the folks that say the 3.55 gear sets was/is not an option for that combo. Similar to GM, the 4.3 V6 only has a 3.23 option in rwd, but 4wd you can get a 3.42! The 5.3 has some similar available or not available options too! I'm not familiar with the Dodge ooptions, but will assume they have some similar availability options too!

I have no experience with the 2.7 EB but I do own a 3.5 EB with heavy tow package. I love the truck and this year we put about 7000 miles on it while towing a 3000 pound TT. IT handled like a dream. The towing package adds so much to the truck's towing ability, I will never own another truck without the heavy tow package.
