I had read that there wasn’t really any difference either, but some claim that the 4600’s ride better…
It’s all in their minds.

The only difference is the extended length of the front 4600 and 5100’s. The valving is the same.
And the compressed and extended length difference, specifically how insignificant it is, also goes to show what a joke it is that the front 5100's are labeled as being for 2-2.5" lift.
Thanks for all the opinions everyone. I will ask one more question: Anyone have any experience with Bilstein 5160's with the remote res? Cheaper than fox. Might be an option

Anyone who claims you can not help the ride with shocks has never been in a Raptor. The Fox 2.5 resi's on those trucks make it ride like a dream on washboard, better if you have them custom valved.
With 10 miles a day, which I often do as well on CO mtn roads Fox 2.0 res would be my choice, 2,5's if the budget allows and a set of springs from Deaver though a good ride and hauling a 3000 lb pin weight are generally mutually exclusive.
My F350 gas has 5100's and it is the perfect compromise of performance cost and durability for me. I can feel a substantial difference in shock performance with the 5100s. I also run around 42 psi cold in the rear tires and have 35" tall tires on the truck. Still rides like a truck but with better control. Can still get sideways on washboard but much less so.
have been, have worked on them, have done baja trips, our toyota keeps up with raptors. guess what...raptors leaf springs are incredibly soft, look up the payload vs a normal f150. also 35's on 17's. so, softer springs, less PSI and more sidewall. the shocks control the axle movement.
comparing a half ton truck that is light duty in the half ton segment to a 3/4 is just silly.
I had Fox 2.5's on my 2013 and they were very good at taming the bumps. I've used Monroe Magnums, Rancho 9000's, Bilstein 4600's & 5100's. I did not really notice any improvement like I did with the Fox 2.5's in terms of ride quality, but the Bilstein's never wore out. The Monroes & Ranchos were ready for replacement at about 50k miles.
I had stock FX4 shocks on my 19 and thought losing teeth and urinating blood was normal after driving. (This is obviously an exaggeration for comedic effect.)
Then I spent $400 on Bilstein 4600s and the ride quality improved - same stock springs, height, tire pressures. The key metric here is that only I could tell a difference; my wife said she only felt a mild improvement in "freeway fat shaking" on her body. On washboard roads, I thought the 4600s were as bad as the FX4s.
So, I subsequently spent 5x the money on custom-valved Fox 2.0 remote reservoir shocks with adjustable low speed compression (LSC). They are significantly better and my wife says she definitely notices a difference, especially in the reduced "freeway fat shaking." On washboard roads, the Fox 2.0s are significantly better than the 4600s.
Shocks are super subjective - plenty of people told me I was wasting my money but I really like the Fox 2.0 remote resi shocks, with the custom valving.
