I finally got to do a test tow with our fifth wheel today. I knew immediately the ride was way too harsh. I could really feel the bumps. The springs come with 2 half inch spacers and a one inch. I had already removed one of the half inch spacers so I removed the other one. Much, much better ride wise. In fact, it was smoother than it was with my previous 17 F350 dually.
Awesome - you asked my exact question and got plenty of good answers - I pull a comparable 5-er and was surprised by the amount of sag in the rear. I really don't want to mess with airbags again either and I have all the same concerns - the ride empty as well as under load. Looks like I will target the 1500 SSR-127-47 black ones - You went with one 1" spacer? Also, I didn't see you re-comment on if there was any additional sag after removing the 1/2" spacer.
So my concern with the yellow ones is that they seemed overkill as the 350 suspension is plenty for that pin weight but trying to remove the drop in the back.
I will look and see what spacers I used tomorrow since I can't remember. The fifth wheel I had when I posted this was a 2013 Excel Winslow with a 3200 pound hitch weight and 16,300 total weight fully loaded for a trip. We had it for 8 years and at the end of May we traded it for a 2020 Jayco Pinnacle 32RLTS with a 3100 hitch weight and 14,700 total, again fully loaded for a month long trip. I had chucking issues with the Excel from day 1, I think because it was a rear kitchen model and too much of its weight was in the rear and not enough on the pin. The only thing that cured it was an air ride hitch. When I changed trucks last December I sold the air ride hitch and got a Reese Goose Box for the Excel. The Goose Box has an air bag and 2 shock absorbers which helped but I was still not happy with the ride so I got the Sumo's, which did help. When we got the Pinnacle I didn't do a thing to the Sumo's, had the dealer transfer the Goose Box to it and the ride is the best we have ever had with any truck/fifth wheel combo we have owned, by a bunch. It is an absolute pleasure to tow the Pinnacle compared to our prior experiences. We are on our 6th fifth wheel and more trucks than I care to say so I feel like I have plenty of samples to make a judgement.

I looked and I used a single half inch spacer. It's been a month or so since I last hooked up but I think the Sumo's barely touch when the Pinnacle is attached and I'm sitting very close to level. A great ride like I already said.
I put Timbrens on the rear and have noticed a much bouncier ride when loaded. I'm assuming the Sumo Rebels would have the same issue as they have a similar disconnected spring design. Anyone else notice this?

Thanks for the quick reply. I am also looking at the Timber's - same price range..I have a strange feeling that I might also be replacing my Andersen Ultimate Hitch for a Reese Goosebox but only one change at a time...leveling the truck out will have some effect on the 5-ers ride. At this point I am pretty sure I will not go back with Airbags. I have had mixed results from having them on my 32ft. motorhome that always leaked some and had to always put air in. And then comparing with my F250 with onboard AirComp that was absolutely awesome but have owned less than a year and the jury is still out on longevity.
It would seem to me that if you're going to put them on, it would make sense to just go ahead and put the yellow ones on since they don't do anything until you have a load on them. Then if you change the load or get a bigger 5th wheel you're all set. Don't understand the logic of going with a softer "black" one for only 20 bucks cheaper. I've also been racking my brain on this. My 22 f-350 dually is scheduled to be built the first week of Nov, and I'm trying to be ready for it. My 5th wheel has a pin weight of 2350 according to the CAT scale. My 250 squatted quite a bit, so I added air bags, which I don't want to do on the 350
Agree on the rears. Yellow which I think are 2500lb ver on my f-450
for the fronts I went with blue, which I think are 1000lb version
The theory with playing with different versions is that even empty the normal wheel travel results in compression so you need to decide how much empty hardness you want.
I understand what your saying, but if you leave the proper gap, it shouldn't hit. These 350's and 450's are pretty stiff.
on my 3019 f-450
yes thank have 1” gap on front and back and there is plenty of compression.
so much so that they act like poo goo sticks and bounce back when empty more than I would like …but I need the yellows in the back for a heavy slide in and I tow a trailer when they he slide in is installed.
to help with the bounce back I’m moving up to fox 2.5’s and setting the dsc to max.
Well hell, with that comment, I'm thinking I should just stick to the black ones. Don't want any bounce back, and all I'll be towing is a 5th wheel.. Perhaps a heavier one in the future, but got to have that "spouse approval". She wasn't too happy about my getting that dually in the first place lol. Everything I read on their web site kind of tells me that the black ones are all I need, but I see that on the forums most use the Yellow. Maybe I'm just overthinking it.
I have yellows in back, blues in front. You won't have a gap on the front set, they are constantly engaged. I found that they smoothed out the ride a bit. The rears have all the spacers in and unloaded I can slip my hand between the spring and the bump stop catch.
