I entered my vehicle info on the Airlift website to see the options that will fit - I want the bags with the internal jounce bumper - and the two listed are #88341 or 94341. eTrailer came up with just 88341. But there's a note on the Airlift page that says: "Will not fit factory air or commercial chassis vehicles. Fits most in-bed hitches"

But what would factory air have to do with rear axle airbags? I called them and they confirmed that indeed they won't fit my 2020 Silverado. I asked the question a few different ways because I don't see the connection. Maybe there would be some electrical issue/fuse availability for a compressor, but I was just looking at the bags.

Anyone out there with a 2020 GMC or Chevy 2500 who's using the 88341 airbags? I saw some reviews on eTrailer from GMC owners that say they love them, but it may not be the same part number.
