I looked up the part numbers and the rear shocks are the same on a 4x4 as they are on an fx4. Only the fronts are different.

I just compared my dad's KR w/FX4 to my Lariat w/o FX4 and you are correct. I apologize.


That makes my quest easier. Waiting for Bilstein to release a 5100 for the front of the 2014+ geometry.

this has become a big problem for me. I agree with most of what everyone is saying. on the highway at speed the truck moves around a little too much and the rear seems to cycle through the travel a lot and top out with too little rebound. truck is not composed. sharp hard hits such as expansion joints and potholes create a definite chatter. now this has nothing to do with the fx4 package sadly as I drove my buddies 5.0 scab and his rides the same as mine. we have different spring rates front to back as my 2.7 fx4 scab. what is common is we both have the 20" wheels with hankook tires. the tires have great grip and smooth quiet rotation. today I drove a 2016 crew with 3.5l as a service loaner and it had 17" wheels with 44psi on the tires and it was like a dream compared to mine. no staring at the road to avoid the next manhole, pothole, etc. While I know that changing the rims and tires will help. the stock shocks are still bad as per my earlier comments. could I live with that ride. probably, however, I might as well upgrade the shocks first to see what it does. so I have fox 2.0 on order. but im very concerned that it will ride too stiffly as the coils are left over from the design for the 2014's.


anyone had any luck with any other shocks?

They shortened the leaf springs in the rear. It is for cornering and handling, but ride quality took a major hit.
I really wish the "Hellwig Drones" would stop coming into every thread about rough ride and saying rear sway bars will fix it. They may help with curves and turns or uneven bumps, but the major complaint is the spine jarring result of both rear tires hitting a bump at the same time (like an expansion joint). A rear swaybar won't fix this!!! The FX4 shocks are the softest shocks you could imagine and the rear is still way too stiff. Stiffer Bilstein or Fox shocks do not fix the issue.

I had the same concerns as you before ordering fox 2.0's. Now that I have them I can assure you theyre stiffer and smoother than stock. By stiffer I mean less floaty and bouncg feeling, but softer over the small little bumps. They do take a little while to break in so give them time. Over larger bumps they do make noise but absorb very well. With being set at 2" they don't have a lot of up gravel so they do top out over larger drop off type bumps like pot holes and speed bumps, but it's only a noise and not harsh riding. Ive owned rancho quicklifts, bilstein 4600 and 5100's in the past and the fox 2.0's are the best out of all of them. The only concern I have is that they may even be too soft.

Disagree with you 100%. I don't think my truck rode too stiff in the rear in the first place, but with fox 2.0's its even more compliant and the back end gets thrown around a lot less. It's not the shorter rear leafs that's the problem. It's the fact that the bed weighs nothing. When the rear tires take a hit the bed can't counter act the movement. All the people that complain the rear is too stiff from what I have seen are running lt tires. Usually heavy ones too that make the problem even worse cause the bed has to be even heavier to counter act the fast movement of a larger tire.

I have a 2016 XLT FX4 Super Crew and ride is fine but I am on 18" not 20". I did replace my tires with E load BF Goodrich KO2's and it is a little firmer due to the 10 ply's and air pressure but far better ride than my older Ford's.

^^ What size BFG KO2s did you install?

Several threads on this concern, besides the lack of control the driver and occupants feel, they also have an uncomfortable ride.

Lightweight bed sitting atop heavy load capacity suspension!

Google the thread Toyota Tundra Bouncing Baby Head. Or use this link below.


Now the Tundra problem is due to their flexing frame between the cab and bed. But the vendors fix, basically bed weight, helps solve that problem.

Perhaps someone could try a similar test using bags of sand, to see if it works? Or give the vendor a call, perhaps they can test on a new Ford to see if it works.

Either way, it's one of several design flaws in the new Ford F-150's. Hopefully Ford will take notice a resolve.

And No, don't work for vendor, but had a used Tundra as a second vehicle at one point and it had the problem, they all do. Now Toyota did a TSB, softer cab to frame mounts, to help isolate the bounce, but did not fix.

I'm purposely reviving this thread because I'm confused. It seems some people say a "stiff" or "hard" suspension creates the bumpy ride while other say a "soft" suspension does. Which is it? My truck feels like it wants to fish tail every time I drive over a bump at high speed. And on roads that are not continuous but have sections (I don't know how to better describe it), it feels like that video.

What would be the best way to make the ride less bumpy? I don't plan to tow anything or carry much weight on the bed. 4x4 Lariat if it matters (NOT FX).
