Why Ford have such lame rear end gear ratios?

So Iíve reviewed a few reviews online plus watched several youtube videos on towing in extreme mountains and see the Powerstroke just doesnít cut the mustard as compared to Ram and Chevrolet. From what I can tell though Chevrolet and Ram offer a 3.73 and 4.10 rear end plus GM has the 7speed tranny. Ford has a 3.31 and 3.55 with a 6 speed. So why is Ford going with such high ratios? No wonder they canít compare pulling against 3/4 and 1ton trucks. Also, I wanted the 3.55 ratio in a F350 but just realized I must go with the camper package (stiffer springs) in order to get it. Totally donít understand....

Dont know about GM but Ram in non Dually DIESEL is 3.42 ONLY. TO GET 373 OR 410 with a Diesel you must have a DRW.

My 2015 F350 SRW had the 3.55. It pulled my 18,000 lb. toy hauler like a champ.

That’s a great question! I would lave loved to have a 3.73 and 4.10 option just to compensate for taller tires that a lot of us put on our trucks.
I think the 3.42 in the Ram is only if you get the high output Cummins and Aisin tranny (which is a hefty upgrade too $$). I’m guessing it’s to compensate for the different output ratio of the Aisin. I remember being disappointed while building a Ram too.

That's probably why they are able to pull a quicker time on their YouTube commercials. I bet they are not apples to apples equipped. My '18 F350 PSD Dually has 4.10's in it and it pulls great!

i think you are correct. I built a Ram without the Aisin tranny and all three ratio options were available. As another poster mentioned iím Going with one size larger tire on a 18Ē wheel so need a little lower gearing to keep everything the same. I will only buy a super duty just hate to so a GM whip us up those mountains. From personal experience the GM trucks just donít handle the weight like a super duty but would like to us have a more aggressive option if the buyer wants one. Iím probably going with the 3.55 in my new F350 but will have to change the front springs out if itís a little stiff on the local dirt roads. Just seems Ford shouldnít force us in a corner for something we donít need.

Change to what you want for a ratio. I changed my '79 to 4.10's, I ordered my 05 F350 with 3.73's changed them to 4.10's (should have gone with 4.30's). I now have a '18 F350 that I ordered with 3.55's, debating to go with 3.73's or 4.10's.

Ram is 3.43 UNLESS you get the dually. Then it is 3.43, 3.73, 4.10. Unless you get the manual, then the best you can get is 3.73.

Chevy is 3.73 no matter what.

Ford is 3.31 or 3.55 in SRW. 3.55 or 4.10 in dually. 4.30 only in F450

These are all diesel engines. Gas options are different

In the Ram you can only get the 3.73 and 4.10 gearing on DRW trucks w/Cummins.

Those comparison videos are for entertainment and are not real tests. Those guys have no understanding of proper testing. There is way to much wrong with their methods to try and list here. Even if the tests were done properly you shouldn't base your buying decision on the results of a single test, on one specific climb, unless that particular climb is your primary use.

itís more than just a single test there actually multiple reviews and even some people on this forum that Iíve noticed the same issue. My point is why does Ford not give someone the option for lower gearing if they want it. Many buyers plan to upsize tires thus raising the effective ratio. Not only does Ford not offer a 3.73 or 4.10 ratio but also forces you to take on other options there may not be desired. Basically they are saying take the 3.31 and like it. Just seems to me someone missed the boat on this at Ford. Either way Iím going to try the 3.55ís and worst case scenario is to spend even more money changing out the front springs.

That’s why I love the 6.2 4.30 combo

Buddy of mine has a '16 Ram 4x2 DRW with the Cummins and a 3.42 rear. I let him drive my truck and now he's thinking Ford...both of us pull camper's but he only pull's a 9K pound bumper pull.
