After about a year of reading this thread I finally pulled the trigger. 2018 Eibach and Deavers +3.
Like many others, I was worried about ruining the ride of the Raptor but I definitely prefer this setup over stock. The nose dive is gone, less body roll in the corners, and axle hop is reduced. Overall, pretty happy.
In the future I may see about swapping in some custom Deavers +4 or having my +3's re-arched to +4. I got the full 2.5" of lift up front and I'd prefer to get a little rake back as I do haul/tow stuff on occasion. I thought about the Icons but they looked a little weak to me and I didn't particularly want the extra 20% stiffness of setting 2.
