Agreed. Before I installed the Rancho coils and shocks the truck felt mushy and a bit unstable with wheel hop when hitting bumps in a curve. That all went south after the upgrade.
I had actually planned to add a rear stabilizer bar next but it is no longer necessary. For a $50K+ truck you'd think Ford would beef up the suspension a bit. But that's not new for them. Every Ford truck I've owned has needed some kind of help in the suspension department.
That's ok, I'd still rather own a Ford over any other manufacturer.

Like someone once said: "I'd rather push my Ford than drive a Chevy"
I'm pretty disappointed that Ford hasn't fixed the issue. Especially since all it takes are different shocks. I've driven Fords since 74 and just drove the first Aluminum FX4 a couple weeks ago. I also get to drive new Chevy's and Dodges. Were I not brand loyal, I would buy a Chevy over a Ford on ride quality.

I agree that the new Chevys have better ride quality. But I had a 2000 with Z71 package (the GM equivalent to FX4), and it had the same harsh ride in the back as my F150 does. I cured that one with Rancho adjustables, so I'm leaning towards the Rancho for the F150, but I haven't 100% decided yet.
I think the ride quality is greatly affected by the tire/wheel size. I had a 2015 XLT (18" wheels), I just traded it for a 2015 King Ranch which has 20" wheels and lower profile tires. The XLT had a smoother ride.
So I finally got some forest service roads under the truck this weekend. I'd removed some weight from the back, but still had my canopy on (190lbs) and weekend gear (say 50lbs). That should help keep things calm. I'm also running my tires at 40 PSI, which is 5psi higher than the door jam recommendations, but still well under the max PSI. In theory the higher PSI will make things more jumpy. No way to tell if the two offset each other or if one is a more dominate factor. But I'd say my load and conditions are within normal ranges.
The shocks actually worked pretty well when I hit some bumps and mud. They absorbed the movement fairly well, but it did feel like they were reaching their limits. But the rear broke free on even the most basic washboard ruts. Especially if I was going up a hill and on the throttle (even mild throttle). They're just not up for the task of handling the undulations induced by washboards hitting both ends at the same time. But I think the crappy OEM tires are part of the problem. They're amazing freeway tires, but they're not the right tread for the FX4 package. Losing grip and spinning just adds to the problem.
Neither were so bad I'll trade them out now. But both are on my watch list...
Only had to wait 2 months for the Fox 2.0 coilovers. Getting ready to install and need some torque specs for upper control arm, tie rod, axle nut and rear shocks.

Fox coilovers did not come with the specs?? Wow...that is interesting.
If unable to find here at fte, then I suggest calling Fox directly and asking them.
OBTW: I am totally interested how the install goes...and the ride quality after!!
After reading this thread, does it make more sense to not get the FX4 package and use that money to get better shocks?
I don't think you can get electronic locking rear diif, hill decsent control and skid plates without getting the FX4 package in 2016. Not sure about 2017. If you don't care about those things, then save your money.
The skid plates are weak sauce too. If you can get the locker separate, I might just go with the locker and then replace the shocks and install aftermarket skid plates.
