Kelderman Rear Air Suspension Spacer Kit. Listed for 2014-18. Can it be used on 2020?

I have a 2020, 2500 long bed crew Lariat . I emailed Kelderman & they said they don't know if it would work on later models. I am asking if it can be used without tossing a code. Curious if anyone has tried the kit on a later model with success.
The little tie rods that read the truck height looks like they may be adjustable as they are threaded into small ball joints. Would that need to be done ?
First post here. Thanks for any info.
