Features to know about
Stay Level and Confident Under Load: 1,400-lb Rear Suspension Support
Heavy hauling or towing can make the rear end sag and the steering feel light. These SumoSprings Solo helper springs add up to 1,400 lbs of rear support at 50-percent compression to keep your ride level and steady when you’re carrying a heavy load. By cushioning bumps and supporting weight, they help maintain traction, steering control, and proper headlight aim so you stay confident behind the wheel.
Smooth Ride Whether Loaded or Empty: Progressive Load Control
These microcellular urethane springs adapt automatically to whatever you’re hauling. Lighter loads compress the springs easily for soft engagement and a smooth ride, while heavier loads can compress them by as much as 80 percent for extra support. The progressive design keeps things comfortable when you’re unloaded but firm and controlled when the weight piles on.
Stable Handling Through Turns and Crosswinds: Independent Spring Action
Each side of the suspension works on its own to handle uneven or off-center loads. That independent action helps cut down on body roll during sharp turns and keeps your rig stable in crosswinds or when a passing truck pushes air your way. With less sway and bounce, the vehicle feels more planted and predictable on the road.
Built to Withstand Real-World Conditions: Durable Urethane Construction
The high-density microcellular urethane resists abrasion, oils, road salts, and UV rays while performing in temperatures from -25 F to 200 F. The springs compress straight up and down with minimal side expansion, so they fit cleanly in tight spots without rubbing against nearby parts. There’s no tubing or air pressure to maintain—just a simple, no-drill setup that’s ready to handle years of rough roads without fuss.

Together with the Hellwig anti-sway bar and front sumo springs this upgrade has really changed the way she handles and feels on the road.

Installed these rear SSR-338-54 and front SSF-106-47 on my 2016 Mercedes Sprinter RV conversion (Thor Citation 24SR)
Easy install. Did this myself and only had to jack up each side of the RV about 6 in. Didn't have to get the tires off the ground or removed the tires. The hardest part of the front where getting the bolts back in through the recessed hole in the suspension to bolt them in place. The rear locked right into place. Total install time about an hour. Only a short trip taken so far but sway seems to have been reduced. Will do a long trip soon to test out.

These were for my airstream/mercedes sprinter. A few years prior I installed a set on my Winnebago View. Installation on the view was easy and the ride was more stable. Installation of this set of Sumos was extremely difficult. I ended up having to trim a lot off the mounting tabs in order to get them to fit. I probably should have returned them but I needed to leave on a trip. The Sumos are still in place and they do help a bit.

Very easy install. I used my leveling jacks to slightly raise the rear end of my RV. Quickly removed old bumpers, and snapped the Sumo Springs in place. 5 minutes per side. I had dealer quotes of $600.00 and $$1,000.00.
I spent $250.00 and couldn't be happier. The body roll is greatly reduced, and the ride feels more solid. Excellent product.

Easy to install with leveling Jacks on your vehicle (LTV UNITY RV). Lifted the rear body with the leveling Jacks and used a screw driver to pry off the bump stops. Placed the rear tab of the sumospring in and used a screw driver to force the front tap into place, almost to easy. Took only 15 minutes total if that.

The Sumosprings are working great, it cuts down on rocking of the van when coming out of the driveway and when going over bumps now everything doesnt get thrown around, well worth it.

After installing the sumo lowered vehicle and it barely brushed the top of the axle, acts like it needs something more on top of the axle for the springs to rest on. Very displeased.

Installed on a 2019 Sprinter 3500 RV. The springs move around in the housing too much and end up crooked (front to back). It wasn't till I tied them tightly to one end using wire that they sat right above the axle and stayed there. I purchased them to solve the sway problem when riding over uneven pavement/road and was disappointed at the minor improvement. I purchased the ones recommended for my vehicle but I'm wondering if there is a more robust alternative.

I reached out to the manufacturer about this, as this issue stands out because Super Springs is a popular brand due to their ease of use, installation, and performance. They got back with me and had a few suggestions for you. They said, The needed correction could be as simple as bending the edgeslips of the OE brackets [they are quite malleable] flatter, or each inward slightly with a vice grip or similar to engage our spring more. Of course although remote, a quick measurement of the cut out portion of our spring should be taken to ensure that it is not under tolerance. The narrowest point of the cut out should be approx. two point nine inches wide. If you are still interested in getting a more robust set up like you mentioned, I would recommend part # RM-1209-131 for the real axle and part # SSF-106-40 for the front axle.

These work exactly as stated on my 2018 sprinter class C. They do not make the ride harsh at all. The yellows combined with an upgraded sway bar helped stop the sway of coming out of a driveway tremendously. Sway from wind and being passed by trucks was also greatly reduced. The addition of upgraded shocks make it so that I can drive one handed the majority of the time now. Recently had the chance to test these in a long run of coastal highway one in northern CA, they made the extremely windy road a pleasure to drive, even with the bad road conditions. Only scored a 4 and not a 5 because they do not solve all of the issues by themselves, but are an integral part of a total solution.

Sumo springs were extremely easy to install and took less than 30 minutes.. They wee installed in a Sprinter based Winnebago RV to help with the swaying of the vehicle when maneuvering over curb entrances and driveways etc. They worked well restricting the swaying of the vehicle. They have now been in for a year and the improvement in driving appears normal to me. I was weighing both the Sumo Springs and Sway Bar installation but the improvement with the Sumo springs alone was enough to avoid the beefed up sway bar modification. Very happy with the product.

If you have been on the fence about whether or not to add Sumo Springs to your Isata 3. I have to say do it now, don’t wait! The ride is greatly improved and the handling is way more confident. Body roll and rocking is diminished. Going up hill over a pass, pulling a 14 foot cargo trailer, I could keep my foot into the throttle and under power through the curves instead of lifting and losing momentum. Downhill I was able to stay a little more off the brakes and drive through the corners. Yellow Sumo Spring set on the rear and black up front(cab over). Purchased from eTrailer.

Excellent product. I would highly recommend this product for anyone that wants to make their 3500 sprinter easier to drive in high crosswinds or help stabilize the swaying from lane changes. Also I found a vast improvement in drivability when towing a trailer. The sway that happens when pulling out of service station driveways or onto uneven intersections was vastly improved.

After much research, I decided on these Summo Super Springs for my 2016 Mercedes Sprinter Interstate 3500 RV. They are extremely highly rated by many people and many sources. By adding these units, there will be will additional support for our new electric bikes. Although untested, as yet, due to the "no travel" COVID virus, I am sure that the additional support on the RV frame will provide a better, safer and more comfortable ride.

After reading all kinds of reviews we finally broke down and ordered Sumo Springs for a 2011 Winnebago View on a Sprinter chassis. We’d been plagued with a top heavy vehicle that tended to sway and rock causing white knuckles on some of the smaller roads and the same occurred on freeways when getting passed by semis. The Sumo Springs greatly mitigated all that. Now the RV goes where I aim it in a straight line without the drama. It also rides smoother and provides some lift at the rear of the vehicle which is good because it doesn’t have much clearance. No more white knuckles and a more confident ride. etrailer ,as usual, shipped fast . They’re one of the best internet retailers you’ll find.

Transformed the handling of my Mercedes Benz class B rv. I installed both front and rear components. The sway is greatly reduced and dive is almost eliminated entirely. I won't want to drive the rv without the components. I only wish I had put the components in from mile one. Simply put, they transformed the driving experience. Highly recommended.

We have noticed a firmer-steady road ride from our 2018 Winnebago Navion by our purchase of the Sumo Springs. We learned of this product by watching other RV owners online video's from their installation and showcasing the results by driving it down the road.

- How to Fix Sway on Highway in 2020 Delano with Mercedes 3500 ChassisHi Todd, I know exactly the feeling you’re describing, and you’re definitely not alone. That floaty, pushy feeling at highway speeds, especially when trucks pass, is really common on the Sprinter 3500 chassis with a taller coach like your Tiburon, and it can make for a pretty tense drive. You’re absolutely looking in the right direction with the upgrades you mentioned. The biggest improvement usually comes from adding a rear sway bar first, and for your setup I would start with the Hellwig...
view full answer... - SumoSprings Kit Recommendation for a 2022 Renegade MotorhomeHello Pierrelavoie! Yes, the SumoSprings kits will help to soften the ride up a little since they are progressive springs which means they provide more support as more weight is placed on them. Since your 2022 Renegade is a larger Class C motorhome I recommend going with the 1,400 lb SumoSprings Kit # SSR-338-54 over the 900 lb Kit # SSR-338-47 simply because your motorhome will likely need it. I'm attaching an installation video of this kit on a 2022 MB motorhome for your reference.
view full answer... - Should I Install the SumoSprings or Timbrens on My Class C Motorhome to Help with Body Roll?Hello Ed, Personally, I like the SumoSprings better. I have recommended them to many people for the exact reason you are looking to add them, to get some color back into those white knuckles. I only recommend the Timbrens for someone who is under a constant load, like with an in-bed truck camper, because when you are unloaded they can cause the harsh ride you mentioned. For your 2023 Class C on a Mercedes-Benz Sprinter 3500: For 4 Wheel Drive: Front # SSF-327-47, Rear # SS55FR For 2...

The # SSF-106-47 is for the 2WD models and does not include a spacer whereas the part # SSF-327-47 is for the 4WD versions which requires the spacer. Do you have a 2WD model?

The Timbrens are great for support but they have a reputation as being a bit harsh whereas the SumoSprings are known to help with ride quality and stability more.
