Welcome to FRF
First things first, post a picture of your Raptor or we are forced to conclude it’s really a prius.
Your use case should dictate what mods you investigate. You should sit tight until you identify things you really want to improve first, then start researching those few things, rather than trusting the guidance of random internet strangers.
A lot of the mods sound simple and easy, but they’re far from it. For example, the B&O is not simple or easy or cheap to modify, so you need to really think whether or not it needs your financial attention.
If your use case is a lot of commuting, powertrain modifications could cost you your warranty so keep that in mind.
Suspension mods: Lots of people throw parts at their truck, trying to one up the Jones’s without any plan, goals or objectives and endup with suspension that’s less compliant, and breaking hard parts. Don’t be that guy. if you mod the suspension, make sure you address all the suspension concerns like new weak points, bracing, spring rates if you go with FRS shocks or similar, travel limits or adjustments, bump stops, etc. OR just go to Raptor Assault to figure out what the truck can do now first.
