Some 2019 vs 2020 height comparison
 

Just noticed this vid...

Some good insight. Sucks headlight and tail lights look to be different. I was looking at anzo headlights and tails.

I wonder if the 350 has been lowered the same amount.

I measured a F250 Tremor yesterday and it's the same height in the front as a 19 F250 and one inch higher in the rear. The 19 F250 was a Lariat with 20 inch wheels.

Didn't have any F350 Tremors to compare.

It's funny, some have said the same as you, then you'll read another saying their Tremor is 3-4" higher than a stock 19 lol. An F350 shouldn't be much different, the diesel Tremor F250 requires the high capacity tow pckg, making it nearly the same as a 350.

So based on the info in that video, and with what you've said, an F250 w/Tremor would be 1/2" higher in front, but 2.5" higher in the rear than a comparable non Ttemor 2020 F250.

If the 350’s are an inch and a half lower in the rear like the 250’s then I definitely will not be rushing out to get a 20/21. Don’t feel like spending a bunch of money to get a truck that sits lower than my 17 and certainly won’t spend any money lifting a new truck just because Ford made a mistake IMO.

I’ll be happy if it’s lower. My 5th wheel will sit level with lots of bed clearance.

From what I saw on a TV interview with a Ford SD rep. at one of the 2020 Auto shows, No. He stated only the F250 series was lowered based upon Ford SD Customer feedback (stating the 19's set too high). He also stated that the F350/450 remain unchanged in ride height.

Thanks for the information.

That's the individual mentioned in this video. There has been some question of accuracy on the subject though, since that guy (ford engineer) contradicted that statement in another video. If the 2019s were considered too high, that would be true of the 350 and 450, not just the 250, also most, if not all 5th wheel owners would be using at least an F350, They are really the only ones who benefit from a lowered ride height.

Its too bad these guys didn't include an F350 comparison in this video.

Is this the video you are referring to?
At 6:00 he says "Just the F250"
Same guy:
At 10:55 he says the dual rear wheeled vehicles were lowered too, which means F350/F450. There is so much misinformation floating around related to this. Who knows what the official change is...

Forget those videos.
One “engineer” was woefully unprepared and was answering technical without actually knowing the facts.
Both the 250 and 350 are lower. 1/2” in the front, 1 1/2” in the rear. The Tremor uses the 17-19 original height.
It’s not much of a difference and hardly noticeable. If you question this, simply take a picture of the rear axle spacer block to see the size change, and you will see for yourself.
The weird thing is that some trucks look like the same height as the 17-19, even with the lower blocks.

The lower height will be the new normal. Ford will lead, and I’m sure the other two truck makers will follow.
Lowering the hood and roof height will also offer better mileage.
I admit I was disappointed when I discovered that the 350 will be lower...contrary to the uninformed engineer, but after seeing them, I’ll survive.

If the new height is unacceptable, you have two choices. Keep what yo have forever, or add the snow plow package for the front to gain back the 1/2” For the rear, it’s a simple rear block difference. I’m not sure if the shocks are different, but it’s in everyone’s interest to toss the shocks from the get-go anyway. I doubt anyone will object once the trucks hit the road.
Still looks pretty awesomehttps://cimg1.ibsrv.net/gimg/www.for...229d8383d.jpeg

1-1/2 lower would be perfect for me. My 5th wheel is that amount off level now.

Here are a few more.
They look like total Ford bad azz and very attractive...

I can tell u there is no way my new Tremor is the same height as a stock 2017. Not sure if stock 2019 was taller but my ‘17 fit in my garage w and inch to spare.
My Tremor won’t-no way no how. It’s at least a couple of inches difference.
Thats my experience YMMV
