Its SO subjective. Specifically for 2015+, I'm certain I've read every F150 King coils review here and the other forum at this point, in addition to reaching out to handfuls of people over PM on forums and instagram. End result is I've only found 2 actual people who have been disappointed in them. One guy said too firm for his liking but dealt with it. Another guy had what seemed to be a defective product, bad sales experience and returned them. Everyone else responded they are "plush" on the street (oh the golden-word) and handle awesome off road. I also like that re-valving kits are plentiful and they are right around the corner from meFrom what I've gathered, the Fox spring rate and damping is less off road worthy than the Kings. On the street, I can dial them back to pretty soft, for what they are. Many might still consider them too firm for their liking. Especially if they are used to Bilstein 5100's.
That said, the Foxs are really awesome, particularly because they're the only coil with dual compression adjusters. But I really do want a bit more lift at 2.5-2.6", so they are out.
I've def thought about it, but I need to see how this all feels first. When camping, my trucks see most of the trail time loaded, but on weekends I sometimes just go out for the day with no load. Therefore, I want to feel it out before softening the rear spring. I may end up needing it as my camping gear keeps seeing to grow.Just an encouragement to spend more (ignore this otherwise), but what about the rear springs? I'm happy as can be with my Icon setup but have been thinking that the back while controlled is too stiff in initial spring rate. Been noticing the back more now than ever and have a set of Icon rear Raptor springs on the way, a bit lighter in rate at the stock +1 inch ride height, the package does include an extra leaf for custom adjusting rates. Looked hard at Deaver but the adjust-ability and price drove me to Icon. Will post after the installation. KM
