Mythical Diff drop kits

I'm looking at getting a 2023/24 1500 and have been weighing options about lifting it. I'm thinking a 3.5" would be the sweet spot for cost and tire size but I would feel much more comfortable including a diff drop along with the upper conrol arm upgrades.

I swear i've found kits for every year for the last decade but apparently after 2019 no one ever needed to use them or make them. Would love some links, or confirmation of ones that are known to fit but don't actually say so.
