I'm not nearly there yet, not that I even know at what mileage it's recommended for the RR, but on a previous F150 Raptor, I had the shocks done at a reputable, local, 4X4 shop here that I believe was even recommended by the FOX rep I corresponded with. If you don't get any other answer here, I would say check if FOX recommends anyone local. Failing that, check for your highly rated, local 4X4 shops.
