I think it also differs from dealership as well. Some may be more of sticklers. I had an issue with my suspension, twice. Both times I took it in they never mentioned or noticed that I had installed Eibach front springs on my ‘19 Raptor. They did initially try to say the problem was due to my Rigid fog lights being wired in, even though they were wired to the Auxiliary plug in wires. This was a smaller Ford dealership and haven’t had much interaction with a Raptor. Probably why they seemed to not know much about them or how to spot aftermarket parts. Just my $.02
