Rancho Shocks vs Bumps

I posted a while back about the steering wheel shake with the road bumps and am ready to tackle it as conservatively as possible. It is not so bad that I even notice it unless the bump or pot hole is really bad so throwing a bunch of money at it is not what I want to do.

From what I can glean from reading the numerous threads on this subject is new shocks can help. I am considering both the Rancho RS9000XL and the new Bilstein 4600 but not sure which way to go. The Bilstein for the 17 Ford front end is so new I couldn't find any reviews on them. Also, I couldn't find a fit for the rear on either shock, only the fronts, which is okay for now but I would like a matched set at some point. Our truck is stock, by the way, and will stay that way. Also, it has the FX4 package with whatever Rancho shocks came with it.

The dually is used mainly for our 3 to 4 months of annual travel with our fifth wheel and not so much as a daily driver. Any comments, experiences or suggestions would be appreciated.

I have been shopping the Bilsteins for my 2018 450 and like you want to do the rears also. I don’t understand why they are not offered.
I swapped front and rear on my 2011 450 to Bilstein and did notice an overall ride improvement. Subjective I know but worked for me.

I will be interested in the replies you get.

I have the Rancho 9000XL shocks on my F-350. I don't have any major shaking problem. The occasional big bump will move the rear end but that's the nature of having a light rear end. I'm still dialing in the Rancho shocks. I'm on a setting of 5 all the way around but I'm going to lower that to 4 before my next outing.

I would be reluctant to go with the 4600 shocks. The 5100 is probably a better option. I had the 5100 shocks on my prior truck and they were comparable to a shock that cost four times as much (SAW Racerunner piggyback) that I ran most of the time.

I thought the 5100's were only for lifted trucks.

is that setting that you use both loaded and unloaded?
Are the Bilstein 5100’s adjustable?

I have Bilstein 5100s on the back of my 2009 F150. They literally make the ride rougher than my 2017 F450. The OEM shocks were much more comfortable. I recommend the RS9000XLs.

As I recall, they are for 0" to 2" of lift. So they should fit an OEM suspension. They fit the non-lifted rear of my prior truck just fine.

For now, I'm using the same setting loaded and unloaded. I supposed I would use a stiffer setting when towing if only I would remember to change it.
