Which Sumo Springs for 2020 View 24D Rear?

[bigalantia]

I have a 2020 view 24d and wanted to add sumosprings to the rear. Does anybody know which ones to get and where to get them at the best price.

I found the best price at etrailer.com

The yellow ones are what I got and highly recommend. I also installed on the front of our View

Shrimpie, could you post a link for the ones you purchased (front and back)? Thanks!

30 min tops for the back, had to jack the front up a bit more so a little longer on the front.

Excellent! Ordering them now.

Take a good look when you install the front. All you are doing is removing the old bump stop and putting in these larger ones but there is an extra hole in the upper control arm. Be careful not to slip it in there by mistake. I did and had a hard time getting it back out

Will do! Thanks for the tip!

Hi Tom, this is Bob I am new to the forum I have a couple of questions regarding the Sumo suspension parts that you used, my rig is a 2023 Navion which i’m told is the same as the View. I tow a 5X10 cargo trailer as well and want to know if the rear springs ( load capability of 1,400 lbs )help to level the load and how is the ride improved or stiffer? On the front i was thinking of using the -47 with a lost capability of 500lbs, do the springs inhance the ride as well? Thank you for your option in advance. Regards, Bob

I'm curious if these rears are worth the $350. My Vita (on a M-B 3500 chassis) wallows like a ruptured duck at slow speeds. My cynical question is "If these make so much of a difference, why doesn't Winnebago (or anyone else) add these by default?"

I don't have a sprinter chassis RV, but I do have Sumo Springs. They are helper springs that are more effective in controlling abrupt up/down motion. Not what I would call wallowing, but maybe you would.

Wallowing is what I would call body roll or tilt. This is a function of the high center of gravity of your Vita. Beefy anti-roll bars are more likely to control this than the Sumos.

As to your question about why it's not done at the factory? Winnebago buys what Mercedes sells. They try to make as few chassis changes after the fact as possible. And, obviously, Mercedes thinks they make an adequate product as is. What the final modified product needs is up for considerable debate and neither manufacturer wants to be part of that debate. That said, some RV manufactures offer Sumo Springs and an option on some models. This is very limited though and not common.

I would add from my experience... nothing solves all these problems. You'll see folks that say Sumos solved all their problems. I'm sure it has for them or they think it does. I find them a so-so addition. I ran Sumos all around for 20,000 miles, removed them for 5,000 miles and evaluated the difference. The result was "meh." Sumos increased ride harshness but added a small amount of body control. In the end I reinstalled them because I had already spent the money to buy them.

One extra rear aftermarket anti-roll bar helped body roll/tilt but didn't "solve" the problem.

One big consideration is my experienced is based on a Ford chassis and a much larger and heavier motorhome. So, it may not relate perfectly to your experience.

My 3500XD does have a beefy anti-sway bar which I guess earlier models (or non-XD?) didn't have. Amazon ended up dropping the price $40 while it was in my cart so I said what the **** and sprang for them; that's a half a tank of diesel lol. I probably won't install them for a while (rubber's not too malleable when it's so cold), so I'll see if they're worth it.
Thanks for the response.

Hello! I just bought a 2024 Vita and plan to get the Sumo Springs mentioned above. I would like to know if you all would recommend I get a sway bar as well, and if so, what kind?
Thank you!

If you have a 2024 Vita (like me! We should compare notes) it's built on a 2022 Mercedes 3500XD chassis and it already has a beefy sway bar.
I ordered the yellow Sumos for me and will be installing them when this PA weather warms up.

Common wisdom is to do only one suspension mod at a time so you can see which ones make what difference. I would drive yours as is for a bit before you try your first mod. Also realize that every suspension mod has a compromise/tradeoff. When I bought my Via I read all about the mods and was preparing to start modding but after driving it as is for a couple years I did nothing. The only real annoying thing is the rocking back and forth when you are driving across a gas station lot over the raised fuel access manholes or exiting from certain driveways, but being used to driving one ton service vans I've just learned to go slow, very slow in those conditions.

Be aware that if you travel forest service or washboard roads a stiffer sway bar can give you less control on these roads at speed as the stiffer suspension will not always let the wheels maintain the same contact pressure with the road that the stock sway bar did.

That's the golden rule of IT, too: Make one change at a time.

 

[Bnystrom]

The one change that will make the biggest difference is replacing the shocks. Agile Offroad/Fox shocks are the gold standard, but Koni adjustable shocks are also highly regarded.

Sumo springs seem to be one of the least effective changes, judging by the number of people who try them and ultimately end up removing them and changing their shocks. If you search RV site, you'll likely be able to find a pair used at a steep discount. That way, at least if you end up not liking them, you haven't wasted much money.

Upgrading to a stiffer Hellwig sway bar makes a big difference in cornering and crosswind stability, but some people say it increases rocking, which I haven't experienced. It was the first suspension change I made and it does exactly what I expected it would do. We prefer to drive secondary roads, so improved cornering is a substantial benefit.

Since then, I've also installed AOR/Fox shocks, which dramatically improved body control and reduced rocking. I'm very happy with this combination of sway bar and shocks.

Are these the ones you got?: https://agileoffroad.com/product/ao-fox-2-0-rear-shocks-sprinter-3500-2wd/

I've been reluctant to try them with the "under 6,500 LBS" rear axle weight recommendation. I'm a bit over that.

edit: these must be the ones: https://agileoffroad.com/product/agile-fox-2-5-rear-shocks-mercedes-sprinter-3500-rv-class-c/

Yes, but when I bought mine, there wasn't a light or heavy option. Looking at my invoice, it just says AOR0016. They work well, so I'm not going worry about it, as the difference is only in the valving. It's not a structural issue. Just for fun, I emailed them to see how the valving in mine compares to the new options. I'll report back when I hear from them.
