SumoSprings for Sprinter Van applications

SuperSprings International (Carpinteria, California) introduced the SumoSprings Solo Kit as a replacement/upgrade for the Sprinter’s front and rear O.E. bump stops.

These products were introduced to enhance load carrying abilities, reduce sway, and improve the overall ride comfort of the Sprinter 2500 and 3500 vans manufactured by Mercedes, Dodge, and Freightliner. SumoSprings Solo – SSF-106-40 (Front kit for 2500 and 3500, 2007-2017) and SSR-329-47 (Rear kit for 2500, 2003-2016) or SSR-338-47 (Rear kit for 3500, 2003-2017) –  are larger than the factory bump stops they replace, creating earlier and smooth engagement.

“Mercedes-Benz recently announced they are expanding the Sprinter lineup with additional chassis, engines, and configurations,” said Gerry L., CEO, SuperSprings. “In response to their popularity, we have committed to engineering a product that matches the expectations of the work truck industry. The goal of the Sprinter SumoSprings is to provide a product that not only enhances the suspension systems, but reduces future maintenance costs while increasing driver/vehicle safety.”

These products are a great addition to fleets. SumoSprings help reduce the costs associated with wear and tear on other suspension components, increase vehicle and operator safety, and are a maintenance-free suspension enhancement.

“The SumoSprings Solo kit on the front of the van eliminated the hard bottoming out I was used to with the factory bump stops,” said Bill C. owner/driver of Mercedes Sprinter 2500. “They reduced the sway at freeway speeds in wind and greatly improved the handling.”

    1. Hi Billy, thanks for reaching out. Could you provide a bit more information about your Winnebago? What is the chassis and GVWR? With that information I should be able to help!

  1. Hi there. I have a 2016 Freightliner Sprinter 2500 4×4 that is converted into a camper van. It appears that the SSF-106-40 is the goto for the front. The website looks like it recommends the SSR-327-47-2 (5000 lb springs). I notice that for most camper vans referenced in the above Q&A, the SSR-338-47 (900 lb springs) are recommended. Is this a 4×4/4×2 difference? Which springs should I go with?

    1. Hey Michael, sounds like you’ve got a nice rig! I’d recommend using the SSF-327-47 in the front and SSR-329-47 in the rear. Unless it is very heavily loaded, then I would also suggest using the SSA55 on the rear. Let us know if you have any additional questions. Thanks!

  2. Im looking for supersprings front and rear for my 2003-sprinter homecar. Total load rear-axel is 2240 kg and front 1560kg (3800kg total). On our trip this summer the load was 2200 rear and 1420 on front. I always get questions if my car is a 2500 or 3500. We dont have these numbers i Norway. Whats the different between 2500 vs 3500? What kind of supersprings can i order?

  3. Hello. I’ve noticed that the SSR-330-47 and SSF-106-40 have been on backorder for a while. Before I place my order I’d like to know when you expect them to be available again. Thank you.

    1. Hi Dirk,

      We do have the SSF-106-40 in stock at the moment. However, the SSR-330-47 is still a few weeks out. The tricky part is we still accept orders for backorders kits. That means an order is placed for at least one kit almost every day. It’s best to place an order regardless of inventory status to save your “spot in line.” Once in house, your order will be fulfilled in it’s entirety.

  4. Hi,
    Thanks for your great work!
    I’m wondering if any of the springs work for a sprinter 312d 1998?

    Much appreciated,

    1. Hi Alex,

      That looks like the equivalent of the Sprinter 2500. We did not start offering any of our suspension solutions for the Sprinter until 2004, so I’m sorry to say we do not have anything that I could recommend for your 1998 model. Thank you for taking the time to reach out, and we apologize we could not be of more assistance.

  5. I have a 2008 Dodge Sprinter 3500 made into a 2010 Fleetwood Quest Class C. Total GVW is 11000 pounds.
    There is considerable side to side sway from the rear when crossing a bump and in the wind. Will Sumo Springs help with this problem?

    1. Hi Deborah Lee,

      Yes, SumoSprings are designed to increase the stability, control, and comfort of the vehicle once installed. Side-to-side sway reduction is one of the primary functions of the design of the SumoSprings. Here are the recommended kits for your 2008 Sprinter 3500:



      Take a look and let me know what you think!

    2. Oui, bonjour, pour un Mercedes sprinter 416 cdi 2.7 w904 de 2004 avez-vous un modèle de Sumo springs pour l’avant, merci de me répondre en français, je ne parle vraiment pas bien anglais et ne le comprends pas vraiment, merci et meilleures salutations, A. Favre de Suisse francophone.

      1. Bonjour, sur la base des informations que vous avez fournies, SSF-402-54 devrait être le bon numéro de pièce. Assurez-vous de vérifier les spécifications des pièces avant de passer commande.

  6. Hi. We own a 2018 Mercedes Sprinter chassis camper van. 4×2, 2500. It looks like the SSR-330-47 ‘s will fit the rear (please correct me if I’m wrong) but what are you recommending for the front? Weight of the fully loaded van is approximately 8500 lbs.
    Thank you for your time, it is very appreciated.

    1. Hi Trina,

      Peter here, thanks for contacting us! You are spot-on with the rear part number, SSR-330-47. For the front, the lighter of the two is typically recommended if there is no cab-over/hang-over and if a softer ride is what you are after. This is part number SSF-106-40. If there is a cab-over/hang-over unit then the SSF-106-47 is recommended as it is a higher spring rate to accommodate for the weight of the front end. Hope this helps, let me know if you have any other questions!

  7. We have a 2018 Dynamax Class C on a 2017 Mercedes Sprinter 3500 chassis. The Dynamax runs pretty much at GVWR max, and have heard the occasional “Bumping” at the back.

    We want to have installed Sumo springs front and back to improve ride and reduce sway. From the comments above, I am still not quite clear which choice we should go with. I see there is either a less-stiff option and one that produces a stiffer ride, but greater sway reduction (I presume). If we go with the former (less-stiff), will it provide enough support and sway reduction, or do we need to go with the latter (stiffer ride)?

    At this stage, we are uncertain whether we will be towing. Can we use the model that you suggest for towing, even if we don’t tow? If we choose this model, will it be an even stiffer ride?

    Thanks for your help.

    1. Hi John,

      Great comments and questions regarding which SumoSprings kits to go with for your Class C on the 2017 Mercedes-Benz Sprinter 3500. Whichever density you go with for front and rear, you will see two sure-fire results: Increased support/capacity, and reduced sway/body roll. As far as comfort and ride quality goes, every person and every application is unique so it all comes down to the “old fashioned butt test.” No one can tell you how YOU will feel when you drive your motorhome with the SumoSprings installed.

      That being said, the most commonly used kit we see for the front is the SSF-106-40 ( as
      this is the softer of the two options, which is important here because the axle is directly below the cabin where you are while driving.
      You’ll be getting additional support plus ensured comfort.

      The rear is a little more subjective, as the SSR-338-47 and SSR-338-54 are similarly used. Both will upgrade the capacity and support while dissipating road shock and vibration. The SSR-338-54 just does this a little more because of the higher spring rate. That won’t make the ride uncomfortable or rough, just a bit more firm. You really can’t go wrong with either one, but to try to help with your decision, I will say we rarely (if ever) have either of these kits returned/exchanged. We also have a great return policy to make sure you are never stuck with something you don’t want or don’t like.

      Rear SumoSprings

      Hope this helps, let me know if you need anything else John!

      1. Thank you, Peter, for getting back to me so quickly! We will pursue your suggestions with our dealer. I’ll probably choose the -54 for the rear, as I like the 1400lb weight capacity.

    1. Hello Gene,

      Thank you for your interest in SumoSprings. So I can give you the most accurate recommendations, may I please have the yr/mk/mdl of your chassis? Example: 2017 Sprinter 3500 2WD. Also, what is your GVWR (gross vehicle weight rating). Also, do you plan on towing? Or, do you have anything heavy mounted on the rear of your vehicle?

      Thank you!

  8. What does the “Note” mean “Do not use on Sprinters with 2″ block on axle” ?
    I’d like to mitigate the curb roll on my converted 2017 Sprinter 3500 cab chassis. I would like to do the installs myself, and have watched two videos that indicated the rears require the chassis be lifted to allow for the rear installation. The fronts look to just need the wheels turned to the stops for clearance above, to get at the top of the mounts with a ratchet. So, I’d like the max support, front and rear, without needing any additional mounting kits or other assistance. I’d like to do it myself. Thanks.

    1. Hello Mike,

      Hector here. Some Sprinter chassis have a 2″block welded on to them that interferes with installment of some of our kits. If you click on the instructions of the SSR-338-47, on the first page it shows a picture of our yellow SumoSpring on top of a 2″ block. The picture will be the lower left one . This is what we mean by the note “Do not use on Sprinters with 2″ block on axle.” I’m glad to hear that you have watched videos on installations of our products, and that they have helped! I hope all goes well on the installation, and you get what you are looking for out of the SumoSprings!
      Please let us know what questions you have.

  9. Hi I have a 2015 sprinter 3500 with a road track CS adventurer conversion, the nose of this vehicle seems to sit abnormally low on flat ground with the rear sitting much higher I do quite often tow a car trailer.
    What can I do to raise the front I level the vehicle and what products do you recommend thanks Larry

    1. Daniel,

      Thank you for your entry, the SSR-329-47 will fit Sprinters from 2002-2016, the SSR-330-47 is the correct spring for the 2017 Sprinter. One thing that I would double check on is the year the chassis was made. Sometimes the chassis will be a year earlier the body. Please let me know if you have any other questions.

  10. Hello,
    I have new 2019 Winnebago View 24V motorhome on a 2018 Mercedes chassis. I would like to reduce highway roll and sway brought about by driving in windy conditions. I plan to tow a 2014 Honda RV about half the time of using the RV. I’ve heard your Sumo springs, in place of the original bump stops, may help settle the steering down. Please tell me which springs will work best for this vehicle configuration.

  11. Hi, I have a 2002 4×4 Sprinter 313 with an updrated front spring from a 416 sprinter to compensate for the added weight of a winch and nudgd bar.Have you suitable Sumosprings to fit my van or could I fit a pair of your custom springs?
    I’m in the UK and we don’t have anything like your availability of after market parts.

    1. Hi Mark,

      Peter with the Sales and Service Team here at SuperSprings! All recommendations we make are based off the year, make, model, and drive type of the vehicle. Is your Sprinter a 2500 or 3500?

  12. i have a 2014 Mercedes Sprinter Navion 24G on the 3500 chassis. I understand my choice for the front is the blue SSF 106-40 but not sure about the rear. I see if you do not tow the recommendation is the SSR-338-47 and if you tow you recommend the SSR-338-54. I do not tow that often but when I do it will be mostly a 2wh drive 1996 Geo Tracker and on some occasions a 4 door 1995 Jeep Cherokee and they are towed 4 wheels down. Also there are many places selling your springs with discounts as well as free shipping. Can you guys do this?

    1. Hi Bobby,

      Peter here with the Sales and Service Team! Thanks for the info you’ve provided. Sounds like you already know your SumoSprings! If your towing is occasional, I still recommend the SSR-338-47. If it is frequent (most of the time), then go with the SSR-338-54. As far as pricing and shipping, go ahead and give me a call or shoot me an email. My direct line is (805) 881-5205, and my email is [email protected]. Thanks Bobby!

  13. Are sumo springs likely to reduce roll on a 2006 Mercedes Vista cruiser sprinter conversion van and what ones would you recommend?

    1. James,

      Thank you for contacting us today. Yes they are designed to reduce body roll by up to 30% with just putting them on the rear. If you install SumoSprings on front and rear the reduction of roll will increase. Is this Sprinter a 3500 series? I need that confirmation if so I recommend going with SSF-106-40 for the front and SSR-338-47 for the rear.

      If you have any questions please feel free to call us!

      Thank you.

  14. We just purchased a 2010 2500 Mercedes Sprinter. When we go over a bump, we hear a “bang” noise from the back. Will this resolve this noise or do we have over problems?

    1. Phyllis,

      Thank you for the question, when you say “bang” do you know where this is coming from? Is it from the vehicle bottoming out, or the vehicle coming in to contact with the bump stop to harsh? If it is one of these two problems the SumoSprings will help with that. They will be a replacement to your current bumbstops and will attach to both the axle and the frame, providing you with constant contact at all times. The part number I would recommend would be the SSR-326-47-1, this will also provide you with 2200lbs of capacity at 50% compression.

      Please let me know if there are any other questions I may help you with.

      Thank you,


  15. i have a 2015 Leisure Travel van, rv Free Spirit Ss on a 3500 Mercedes Sprinter van chassis . Which Sumo Springs do you recommend to replace factory bump stops.

  16. We am looking to install the Sumo Springs kit number SSF-106-47 on my 2016 Sprinter 2500 2WD van. I have noticed that the choices are a 500 lb. and 1000 lb. limit/capacity for the front Sumo Spring kit.
    As we do plan on converting our van into a conversion we are thinking the 1000 lb. kit would be the best fit do you have other recommendations?

    Thank you,

    1. Hi Timothy,

      We recommend going with the SSF-106-40 which will provide more ride comfort and improve the feel to your ride. We recommend the SSF-106-47 for commercial vehicles with constant heavy loads. The SSF-106-47 will have a tighter feel to the ride, and will provide a bit more stiffness than most people with your application. Please see below for a link to the SSF-106-40 in our store:


      Please let us know if you have any further questions.

      Thank you,

      1. Edgar,

        Thank you for your suggestion! We decided to use the SSF-106-47. What a huge difference!!! The ride is now more “solid” feeling and it is as if the van is actually connected to the road. Thank you for your help and the great product for our Sprinter van.

  17. Amazon says the SSF – 106-40 and the SSR-338-47 will NOT fit my 2016 Mercedes Benz Sprinter 3500. Is that true? If so, what product do you recommend?

    1. Thanks for the comment. Unfortunately, the information Amazon posts is not always accurate. In some cases, it is flat out wrong. The SSF-106-40 and SSR-338-47 will fit your Sprinter. Check out the installation instructions. They have color pictures you can compare against your own Sprinter. If you’re at all unsure and would like more details, give our tech line a call on Monday, +1 (800) 898-0720. Have a great weekend!
