You'll need a Risse Racing drop crown to get a 150mm headtube to work with a 40, I've been using a 40 on my 140mm headtube K3 Voima for a couple of years now. There's the full set, or just the upper drop crown. I tried to get an S18 frameset and bought an upper crown, but ended up getting a Crestline and a Dorado instead. The Risse upper crown is 14mm offset, 48mm rake. The Fox lower crown to suit is: 820-12-347 Lower Crown-Steerer, 14mm OS, 48 Rake. The upper and lower set of suitable Fox crowns are: 820-12-353-KIT but I'm not sure which 40s come with that crown set stock, as the Risse crown didn't suit the 2024 Fox 40 29er, or the 2022 Marzocchi 58 27.5 crowns I had.
