It appears Ford changed the front spring codes and part numbers for 2020. Hope fully we can create a list to determine the new codes with the ratings, including Tremor springs. Part numbers I have located are:
LC3C-5310-AKA, ALA, AMA, ANA, APA, ASA, ATA, AVA, AWA (The spring tag refers to the first character in the part number "L" then the spring rating "A*"
If you have a 2020 can you post the following info please.
2020 F*50 (trim)
Door spring Code (66)
Spring Tag (LAV)(larger letters on tag)
Spring rating from sticker if listed.
2020 F350 XLT Tremor 7.3 66 LAV **** (Thanks to 67-4-Me)
2020 F250 Lariat 6.7 MM *** 5200 (thanks to Joe T)
2020 F350 DRW 6.7 ** LAL **** (dealer)
Thank you
Keith

Reason: additional info
Good idea. I wonder if this has something to do with the initial impressions of ride being better than the 17-19. I wonder if shocks are changed too?
I suspect a lot of improved driving feel is really about the electric power steering system.
But... my fingers are still crossed that maybe there will be a softer, taller factory spring on the tremor that we can retrofit. Those of us with gassers are out in the cold on spring lift options.
looking forward to this thread producing some results....
Both
there should be 4 digits on the door sticker above the spring Title (TTSS) or something similar
Then on the spring itself will be a tag. It will have three large letters (LAV) or something similar.

Supposedly they are the same as the 2019 springs and they only raised the rear.
Waiting to see more.
Someone posted the 2020 Tremor 6.7 had the 5200 gawr. That is the stock gawr on the 2020 and 2019 250/350 4x4 6.7.
Example of Spring Code Tag (this is a 2019 F350 Factory Snow Plow Prep spring for the 6.7L Diesel), I would think the 2020's would have a similar Spring Code sticker:
6000# Factory Snow Plow Prep Coil Spring with 6.7L Diesel.
Here is a video below. At the beginningish and towards the last minute of this video he shows the differences.
2019 Taller Front Spring and different upper spring perch?
2020 even taller front upper spring perch and assume shorter springs? Maybe that is how they get some of the lift on the tremor, with the spring perch?
2019 Taller rear block and bracket welded to the rear axle for the bumpstop to hit. 2020 shorter rear block and bracket removed off axle.
What I am assuming and could totally be wrong. The regular 2020 5200lb front springs are actually 2019 gasser springs and they compensated some with a bigger upper spring perch. Would explain the better ride. Rear suspension as mentioned in the video.
The tremor has 2019 5200lb front springs and the bigger upper spring perch? Obviously has taller rear blocks as mentioned.
