Front Suspension Support

A heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your rear axle, your rear tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


Installed spring when it is not compressed

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.


Installed spring when it is compressed

The springs can also compress by as much as 80 percent to support a heavy front load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your rear tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.


The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.


Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).


SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.


The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

  • Best Suspension Enhancement & Steering Stabilizer For 2023 Jayco Greyhawk 27U
    Hi Jeff, I can give you a hand here with suspension upgrades for your 2023 Jayco Greyhawk 27U, though honestly I'd go a different route than the Timbrens # TFEF350 and # TFERSD you mentioned. They'll do their job, but my goodness they can be quite rough on the ride. They are made from a very dense hollow rubber so there just isn't much "give" there and you'll feel it. The better option is definitely SumoSprings because they'll compress based on the weight being transferred so it isn't...

  • SumoSprings Recommendation for 2018 Thor Vegas 27.7 Built on E-450 Chassis
    Yes, we do have confirmed SumoSpring fits for your 2018 Thor Vegas 27.7. For your 2018 Thor Vegas built on a Ford E-450 van chassis you can use front SumoSprings # SSF-106-40 or # SSF-106-47 if the vehicle is 2-wheel drive. There is no SumoSpring option for 4-wheel drive models but if you have a 4x4 then you can instead use Timbren springs # TUMDF70. The difference between the 2 SumoSpring options is capacity. Set # SSF-106-40 is rated at 500 pounds at 50 percent compression whereas...

  • Front SumoSprings Kiti that Fits 2006 Ford Class C E-450
    For the front axle of your 2006 Ford Class C E-450 motorhome we have the SumoSprings kit part # SSF-106-40 as only option. This will give your RV an additional 500 lbs of suspension support. The different colors of kits mostly relates to different capacities and constructions but for front axles there aren't quite as many options since most of the time it's rear support that people are looking for.

  • Recommended Superspring SumoSprings For 2007 E450 Class C Motorhome RV
    The only front mounted hitch confirmed to fit your 2007 E450 Cutaway motorhome is the Draw-Tite Front Mount Trailer Hitch Receiver - Custom Fit - 2" # 65001. This hitch has a maximum 500 lb vertical load. For a motorcycle carrier, I recommend the etrailer Motorcycle Carrier w/ Ramp for 2" Hitch - 76" Long - Steel - 500 lbs # e98873 which weighs about 58 lbs leaving you a capacity of 442 lbs for your motorcycle. The Ultra-Fab # UF48-979033 would also work, weighing in at 51 pounds. For...

  • In Which Order Should SumoSprings Be Installed On A 2006 Fleetwood Jamboree Motorhome
    It doesn't matter which order you install the SumoSprings on your 2006 Fleetwood Jamboree GT 31W motorhome. Typically the rear needs the most help when it comes to enhancement so that's where most people start, but if you're doing both it doesn't really matter. For your Ford E-450 Chassis you would want the SumoSprings Maxim Custom Helper Springs # SSR-106-54-1 for the rear and the SumoSprings Solo Custom Helper Springs # SSF-106-47 for the front. I've attached some videos below to help...

  • SumoSprings For A Winnebago Motorhome On A Mercedes-Benz Sprinter 3500 Chassis
    Hello Allen. For a Winnebago camper on a Sprinter 3500 chassis, I definitely recommend the 1,000 lb Sumo Springs # SSF-106-47. I would go with the 1,000 lb for really any 3500 model, just because they will give you the needed additional support for larger vehicles. They will help a lot to increase stability and get rid of any sagging on the front end.

  • SuperSprings SumoSprings For a 1997 Ford E-350 Cutaway Van Chassis
    SuperSprings offers their SumoSprings in either the 500LB # SSF-106-40 or 1,000LB # SSF-106-47 for the front of your 1997 Ford E-350 cutaway chassis. While they do not have a SumoSpring for the rear the suspension they do have their Stabilizer and Sway Control Kit in either a 1,400LB # SS94VR or 2,500LB # SSA22 kit. While these do not offer the progressive cushioning like the SumoSprings they do greatly increase stability and will help to reduce rear sway. I recommend using the heavier...

  • Comparing 500 Lb and 1,000 Lb Front SumoSprings for a 2013 Mercedes Benz Sprinter
    In regards to the SumoSprings Solo Custom Helper Springs part # SSF-106-47 for 1,000 lbs and part # SSF-106-40 for 500 lbs for a 2013 Mercedes-Benz Sprinter, the difference is the hardness of the spring rather than length. Therefore, they will both engage at the same time but the amount of give for example will be different. The softer 500 lb spring will have more give therefore offers a smoother ride but also does not provide as much body roll reduction as the harder 1,000 lb version....

  • Recommended SumoSprings for Ford E350 Front and Rear Suspension Enhancement
    I'd be happy to assist. For a 2001-2014 E350 van model or 2015-2018 E350 Cutaway, I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-130-54 which have a 2,800 lb capacity at 50% compression. These springs progressively add more support as they compress do you don't have a rigid ride and yet have the support when needed. It will help stabilize your vehicle and reduce body roll. You could alternatively use the # SSR-130-47 which have a 1,500 lb capacity. I've linked...

  • Best Way to Improve Ride Quality on 2018 Ford E-450 Motorhome
    The ride in your 2018 Ford E-450 will be improved to a certain degree by the SumoSprings - Front Axle # SSF-106-40 and Rear Axle # SSR-130-47, but they will not give you a ride that is as cushioned as air bags. So for the main purpose of improving a ride that is stiff and jarring, I do recommend air bags over SumoSprings, with the best option being the Firestone Ride-Rite. The correct fit for these air bags on your '18 E-450 are the following: - Firestone Ride-Rite Air Helper Springs #...

  • What Does the Capacity Mean for Sumo Springs on a 2018 Coachmen Freelander
    This is a great question and one that can cause some confusion. SumoSprings capacity is determined by how much weight it takes to compress the spring down to 50% of its original body height, so a spring like the # SSF-106-40 will compress down to half of it's unweighted height with 500-lbs of pressure. The # SSF-106-47 is going to be a stronger spring with it's 1000-lbs capacity. Keep in mind, these aren't designed to upgrade the GVWR, but they're designed to help cushion the load that...

    I recommend using the SumoSprings Solo Custom Helper Springs Front # SSF-106-47 and Rear # SSR-338-54 on your 2021 Leisure Travel Van. Both these are confirmed to fit the 2 wheel drive 2021 Mercedes-Benz Sprinter 3500 chassis under your van. The front are the heavier black(1,000lbs) rating versus the Blue # SSF-106-40 at only 500lbs. The rear is the yellow(1,400lbs) versus the Black # SSR-338-47 at only 900lbs.

  • What Front and Rear SumoSprings do You Recommend for My 2022 Ford E-350 Chassis?
    For just a little boost on your front and rear suspension on your 2022 Thor Class c on a E-350 Cutaway chassis, I recommend the following setup: - SumoSprings Solo Custom Helper Springs - Front Axle # SSF-106-40 - SumoSprings Maxim Custom Helper Springs - Rear Axle # SSR-106-40-1 With these two sets of SumoSprings, you will have a load-leveling of 500 pounds in the front and 3,000 pounds in the back. The great thing about both of these SumoSpring models is that they do not require any...

  • SumoSpring Helper Spring Recommendations for a 2015 Forest River Motorhome on Sprinter Chassis
    I'd be happy to help! Going with the SumoSprings Solo Custom Helper Springs for your 2015 Forest River RV (on the MB Sprinter chassis) is an excellent idea as they are more forgiving than the Timbrens but they also provide stability for that side to side sway like you said. For the front you want the part # SSF-106-40 that you stated, and for the rear I recommend the yellow kit # SSR-338-54 rated at 1,400 lbs over the black kit # SSR-338-47 rated at 900 lbs.

    Adding the Rear SumoSprings Solo Custom Helper Springs # SSR-329-47 is not going to be required on your 2016 Mercedes-Benz Sprinter 2500 but it will help if you are getting a lot of sag or road shock through your suspension. These will simply replace the hard rubber springs that came on your Sprinter to give you better suspension characteristics. These progressive springs have a capacity up to 900lbs at 50% compression.

  • Best SumoSprings For 2023 East to West Entrada 2700 NS on Ford E-350 Chassis
    Always smart to check, and the heavier-duty rear option is perfect for your 2023 East to West Entrada 2700 NS motorhome on a Ford E350 chassis, though instead of the 500 lb front springs, I would go with the slightly stronger 1,000 lb front springs. So the best option for SumoSprings for your motorhome are the following: - Front Axle: SumoSprings Solo Custom Helper Springs # SSF-106-47 - Rear Axle: SumoSprings Solo Custom Helper Springs # SSR-130-54 The 1,000 lb front springs won't make...

  • Are There SumoSprings Solo Custom Helper Springs for a 1997 Ford E350 Club Wagon
    The SumoSprings Solo Custom Helper Springs are not offered for a 1997 Ford E350 Club Wagon for the rear but I do have a very similar option in the Timbren Rear Suspension Enhancement System part # TFER35092B. The main difference between the two is that the Timbrens are made of a more dense material so they will provide more support.

    We have front SumoSprings that are confirmed as a fit for your 2016 Thor Axis Motorhome, part # SSF-106-40 but at this time we do not have any suspension enhancement setups for the rear. The kit I referenced is the lighter duty kit that would give you a softer ride than the heavy duty.

  • Front SumoSprings Recommendation for 2018 PleasureWay Ascent Built On Mercedes Sprinter 2500
    I would recommend the same as SumoSprings. The temptation is to go with the highest rating as it seems like that would be the most supportive, but in reality you want to go with the best matched capacity which balances ride quality and support. Going with too high of a capacity will give you a harsh ride quality that you wouldn't like. So the kit you'd want then is the part # SSF-106-40 which is the correct fit and capacity.

  • Recommended SumoSprings for 2022 Pleasure-Way Plateau TS
    For your 2022 Pleasure-Way Plateau TS I recommend the SumoSprings Solo Custom Helper Springs # SSF-106-40 for the front axle and # SSR-338-47 for the rear axle. Adding these helper springs would be a great choice. The springs will help minimize sway and absorb bumps and shocks without sacrificing the overall ride quality. They also work independently from each other to help compensate for off-center loads. I have attached a review video along with an installation video for your reference.
