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.

Hello, i installed the Sumo springs on my 2020 M/B 2500 pleasure Way camper van 19.5 foot, if you do not want to go in for the full suspension upgrades for 5 to 6 thousand dollars the Sumo spring is a
decent up grade to help with sway, we aren’t off roaders campers
but they work nice in unimproved campsite. I have about 4500 miles on my camper since I installed them which took about a hour. It did raise the camper by about 1/4”.
I just used a floor jack and big flat screw driver for the back and deep well socket for the front ones. Sorry I didn’t take a video or picture. But so far I would recommend the sumo springs it is better then stock bump blocks.
And thanks to etrailer for getting me the right setup
for my camper.



by:

So glad I found these! Best upgrade for my Winnebago Era Touring Van. Simple to install. I only needed a floor jack to get it done. Van doesnt ride like a boat in a storm anymore. Highly recommend for Sprinter vans.

Would notcould not go back to not having Sumosprings. Best investment for my vans handling.

Ram 2500

I had to loosen the stabilizer bar in order to install the springs. The stabilizer bar is very tight to the springs. I will be able to see after some driving how much stabilzer bar rubs on the springs. The install was on a 2022 Sprinter 2500.



by:

While traveling we had a fellow Pleasure Way owner tell us about the Sumo Springs. We had them installed in the front and rear. It made a huge difference in driving. The RV does not sway on major highways when going at higher speeds.

Worked so well I now have them on another Rv and put them on my power wagon



by:

I had Sumo helper springs installed on my Winnebago Sprinter RV both front and back. It made an amazing difference! It no longer felt like riding in a Conestoga wagon…swaying side to side and bouncing everything to the floor. The ride is now smooth. Driving was easier. Turns are suddenly level instead of feeling like I might turn over. I could not be happier with these products! And it only took 20 minutes to install all four!



by:

This set tightened up the suspension on my Mercedes motor home. Cornering is much better which helps the overall handling. I also replaced the sway bar.

Installed springs on my 2018 thor vegas rv. Haven't got it on the road yet but installation was a snap. I like that they will begin stabilizing and help with ride comfort. Couldn't upload pictures sorry

Easy to install
Smoothed the ride, but
it is still a Class C box truck. Sumo Springs alone will not give provide all I want. So far I have added Helwig sway bars and a steering stabilizer. Next stop high end shocks.

Fast delivery, great customer service, overall great experience. The Sumo springs worked great on my Mercedes sprinter reyo rv. Big improvement.



by:

I was a bit skeptical about these springs, but they do seem to help with the sway and rocking in my Sprinter camper van. I added SumoSprings to the back as well. They were a bit more challenging to install (especially in the front), so I had the dealer install them. It took them more time and effort - more than anticipated. Overall though I am happy with this modification.

2020 Thor Citation Sprinter Motorhome

Easy install; about thirty minutes. It is literally one nut per side. Prep and jacking the vehicle consumes the most time. Seems to be a quality product. Body roll and sway greatly reduced. Basically a much larger bump-stop. This worked well for me, and I think is worth the money.



by:

It's been a year since I bought the SumoSprings and I am very pleased with how they make the coach ride and handle. I bought the softer springs because I wanted a smoother ride over bumps. I installed them and test drove the coach and found it to stiff a ride so I called SumoSprings to see if they made a 3 ring spring which they don't. I than asked if it was possiable to cut 1 ring out and was told it would only void the warranty but would not effect the integrity of the spring, so I did and the coach now has about 3/4" free play and the ride is enjoyable not harsh like it was. I know you cannot modify the springs but this is the best way I found to have a great ride and great handling all in one package. Thanks for opportunity to to explain how it helped.

2018 Mercedes-Benz Sprinter

I’ve had the Sumo Springs on my 2018 PleasureWay Ascent (2017 Mercedes Sprinter chassis) for a year. Originally I just installed Sumos in the rear, because I was experiencing some bottoming of the stock suspension, which made an improvement, but after about a thousand miles, I installed Sumos in the front, also. That made a further improvement. There is less sway on curves and in crosswind conditions, and there is no bottoming over bigger bumps such as railroad tracks. A benefit I didn’t expect is that I also gained about 5/8” ground clearance.

Overall, I am very pleased. In my view, for suspension enhancements, there is no better bang for the buck than Sumos.

Cary A.

4/6/2021

It’s now been two years since I installed the Sumos on my 2018 PleasureWay Ascent 2017 Sprinter chassis. I remain convinced that Sumos are the best bang for the buck suspension enhancement available. I strongly recommend doing both front and rear at the same time—I initially did only the back to counter some bottoming I was experiencing, especially when I carried my Vespa scooter on the back. But after another thousand miles, I installed front Sumos. Overall, the ride was improved, sway was reduced, and although the camper handled fairly well stock, it handles much better with the Sumos in all respects. Plus I gained about 58” clearance. All that, without compromising the ride comfort in any way makes them a really good purchase.



by:

I originally purchased and installed the SSF-106-47 SumoSprings for the front of my 2017 Mercedes camper van. After using the van for a period of time with those springs and consulting with the manufacturer about a few performance issues, I contacted etrailer and requested that they be exchanged for the SSF-106-40 SumoSprings. etrailer willingly replaced the springs and has indicated that they will refund the cost of my original purchase.



by:

These work awesome. Installation took about an hour because finding the right size socket (10mm) to remove the old bumper stop took 45 minutes. No more bouncing and dipping around corners. They also improved and quieted the ride. Well worth the money! Wish I'd put the on the rear, instead of air bags.



by:
2023 Ford E-Series Cutaway

Best bang for your buck! If you have a RV just put them on! It's easy. You don't need to look anywhere else because etrailer is the best.

2016 Mercedes-Benz Sprinter 3500

Product was easy to install, I did not have to remove wheels. One note, the instructions claim the nut for the OEM bump stop and the Sumo replacement is 10MM, it is actually 13MM. Because to installation stud is buried in the suspension member, have a magnet handy and a deep 13MM socket. I used a piece of masking tape to keep the nut in the socket while engaging onto hidden stud. First impressions are favourable as I installed this in conjunction with rear Sumo Springs. Noticeable improvement in sway and stability. Low cost high value modification to my Mercedes Spring RV.



by:
Mercedes-Benz Sprinter

I have a 3500 Sprinter RV. Had the SumoSprings installed front and back for $135 at an independent RV service center that also handles RV's. They had never installed them before. I gave them the installation instructions and some advice I learned from some online videos. Sprinter is unloaded at present but notice it handles better going around turns and curves in that it doesn't lean as much and feels very stable. Need to take on a trip to see how it handles when loaded. I noticed a sort of squeakiness I am not sure was there before. I need to drive it more to determine it is from the SumoSprings.



by:
Winnebago

Purchased for a 2008 Winnebago View. Previously installed read Sumo Springs. As usual, Etrailer quickly processed my order, shipped promptly and included very good installation instructions. Installation took about an hour. Adding the from springs eliminated any wobbling or softness in the ride. The buffeting I experienced when a large semi passed me doing over 70 mph is eliminated. A quick fix to an annoying problem. In an aside: the stock "bumpers require a 13 mm or 1/2" deep socket.

  • Suspension Enhancement Recommendation for 2014 Mercedes-Benz Sprinter 2500
    The Super Springs SumoSprings Solo # SSF-106-40 is for the front axle suspension of the 2014 Mercedes-Benz Sprinter 2500 or 3500. The SumoSprings Maxim # SSR-336-54-1 is for the rear axle of the 3500. For your 2014 Mercedes-Benz Sprinter 2500, I recommend the Timbren Rear Suspension Enhancement System # TMBRSP25A. Trimbren's hollow rubber springs will replace the existing axle bump stops and works to increase stability, reduce rear end sag, and extend the life of your suspension.

  • Are SumoSprings Required To Be Added To Both the Front and Rear on a 2016 Mercedes Sprinter 2500?
    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.

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.

  • Sway Bars and SumoSpring Helper Springs For a 2022 Thor Freedom Elite 23HF
    For your 2022 Thor Freedom Elite 23HF that sits on a Ford E-350 V8 chassis I recommend the Roadmaster Front Anti-Sway Bar # RM-1139-176 and Roadmaster Rear Anti-Sway Bar # RM83ZR. If you have a different chassis please let me know. The SumoSprings Solo Custom Helper Springs Front # SSF-106-40 and Rear # SSR-106-47-1 are great to add with the sway bars. This will help make your drive much safer as it stabilizes the chassis with all the additional weight it has gained from the RV being added.

  • 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...

  • Will SumoSpring Front Helper Springs Raise the Height of a 2017 Thor RV on a Ford E-350 Van Chassis
    With SumoSprings # SSF-106-40 installed on your 2017 Thor motorhome built on the Ford E-350 van chassis the springs will be engaged all the time. This means that the vehicle won't have the natural sag that it would with the stock bump stops and the vehicle may ride slightly higher. But it won't lift the vehicle any higher than it would naturally sit if there was little or no weight on the front axle. I have linked a video showing an example installation for you.

  • 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....

  • 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...

  • 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.

Since a flat towed vehicle does not really load tongue weight on the Thor's hitch the way a trailer does the kit # SSR-130-54 will correct for most of the sag without making the ride too hard. I ran this thinking past my tech contact at SuperSprings and he agreed. For a front axle kit he suggested # SSF-106-40.

  • 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.
