Water fording height on a non-Tremor is no deeper than the center of the hubs (whatever that height may be). The reason is the differentials have breathers on them - holes - that allow for pressure changes as they heat up/cool down. These breathers will allow water into the differentials. If you run with watered down gear oil for a while or under heavy load, that will severely damage your differential.

@ccw thank you, huge insight!! I come from cars much closer to the ground. These breathers, are they something that can be added to a SD or is it just easier to buy a Tremor??Water fording height on a non-Tremor is no deeper than the center of the hubs (whatever that height may be).

On the Tremor they added extended breathers - hoses - so that they draw in/release air from higher up. Thus, if you submerge the differential, it won't let water in.
(If you ever do get water in your differentials, change the fluid as soon as practical.
And to add on for the Tremor: I don't know how high up the breathers go and if they're the limiting factor anymore. If they are higher than some other component that's sensitive to water, then that other component would be the new limiting factor (e.g. air intake, computer module, electrical connection not rated for submersion, etc).Water fording height on a non-Tremor is no deeper than the center of the hubs (whatever that height may be).

No problem! I can't speak to any specific products for the Super Duty differentials, but in general yes breathers can be added aftermarket. It's a common thing for off-roaders to do if they are doing water crossings regularly.
Personally I wouldn't consider the water fording a reason to get the Tremor. It's a nice bonus and doesn't hurt, but I would weigh the front differential, included 35" tires and rock crawl mode far more - depending on your wants. Especially if you consider truly how frequently you will be needing to ford water deeper than the hubs.
Great context on the water fording height. I actually am waiting on 37s" and the Carli kit, i went with no Tremor and the DIY. I'm not too worried about the rock crawl mode. As cool as it sounds, i doubt i will use it. However, i'm still a kid at heart and love to go through water. I'm commited for now!No problem!

By definition it's easier to buy a Tremor, but if you just want the additional water fording ability those are some expensive breathers.
Most people almost never need to ford water that deep. (For context, assuming 35" aftermarket tires, that means you can ford 17.5" of water with a non-Tremor.)
Awesome! Agreed on rock crawl mode not being that valuable to me personally. I know some folks really want it, but I doubt I'll ever use it other than to try it out for fun. If you find breathers that work with the Super Duty, definitely post up links and photos of the install!
Huh, never even considered dust but makes sense! Guess everything for water protection helps with dust lol. I know snorkels are super common for off road vehicles in Africa and Australia because of dust.To elaborate on the axle breathers, they are not just for water fording. I run them on my desert truck as well to fight the dust.
Yes they are easy to add aftermarket if you really want them
