Most OEM coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. If your coil springs are totally squished under a load, the lack of shock absorption can be harsh on your backside, especially if you spend long hours sitting in your vehicle while clearing snow. Insert these helper springs in between the individual coil loops in your front coil springs to help defeat driver fatigue and to better support heavy front loads.

Coil SumoSpring installed between rungs of coil spring

Each doughnut-shaped spring has H-shaped channels at the top and bottom that fit to a rung of each coil in your front coil springs. Inside each round spring, a core of microcellular polyurethane foam adds cushioning between your coils. The cushioning absorbs shock, but also works progressively to better support front loads, and it keeps the front end more level. Unbumpify your ride with these SumoSprings for coil suspensions.

Install went fairly easy once I figured out the best spot to put the jack to lift the van. Really helped to have an oil filter wrench to get the old springs off the back. Took it out for a drive after an much better cornering and much less effect from wind and 18-wheelers. This was on a fairly windy day. No big difference in softness of the ride.


I ordered these for my RAM Promaster 3500 because I had heard from fellow owners that they are a worthwhile addition, for increased stability on the road. The instructions are good, and they weren’t too hard to install myself. They are kind of expensive for a couple of rings of dense foam/plastic, but I guess they must be petty heavy duty. I look forward to my next trip to see how they perform.

Ram ProMaster 2500

I installed the Sumo Springs , front and back, on my 2022 Promaster van before I started my camper conversion. Sumo springs are alimony a must on a build to reduce sway and assist with the constant load in the back of the van. I purchased them from etrailer because of their outstanding customer service

2023 Ram ProMaster 2500

Good communication. Product arrived on time exactly as described. I've ordered many items from etrailer. Always a good experience! Thanks.

2018 Mercedes-Benz Sprinter

This one year review. We have a 2018 Mercedes Metris, it's just a big mini-van, but not a sprinter. The suspension is fairly soft, ok for city driving, but a little soft for 70+. When hauling a trailer we would gently sway, not great, so we got the rear set and it helped quite a bit, we followed with the front set 3 weeks later.

Overall it firmed up the suspension enough to really help without it being too firm. It raised the stance about 1/2" and is relatively easy to install.

Would buy again.


Very easy to install


product worked as designed easy to ins tall

2018 Dodge Ram Pickup

There is a significant improvement in ride comfort and reduced response to high winds and 18 wheelers as they pass, increased stability in turns and, overall, a more comfortable and secure ride. I'm 72 and installed both front and rear alone in under 1.5 hours. Great investment. PS We have a class B, Dodge Ram Promaster 1500 van.

2021 Ford Transit T250

I found myself making 2 big purchases recently for my van conversion and all paths led me to They have delivered my products on-time, and always follow-up with a real person. 5 star treatment.


Such an easy add, anyone carrying weight or conversion van should buy asap.


Just returned from our first trip after installation of coil spring suspension- front axle and SumoSpring Solo Custom Helper Springs-rear axle. A significant difference is noted in ride as there is less bounce and sway. Cornering is more sure and flattened this noted on many curved mountain and rural roads traveled in Western and Central PA. Turnpike travel was smoother as road tar strips were not as notable given a stiffer ride.


I have traveled over 10,000 miles and feel that Sumo Springs for the front axles have been a great addition to my 2014 Winnebago Trend. I also added the Sumo Springs to the rear and new shocks. The ride and stability is much better with all these improvements. I would recommend all these products


Excellent service
Davine was awesome

Dodge Ram Pickup

Easy to install on a Ram Promaster. Good instructions. Definitely improved ride quality - less sway and more stability.

2016 Ram ProMaster 1500

product is good as always and etrailer is superb in assisting customers. 5 stars.......

Ram 2500

Install was a breeze. Leveled out the bouncy front end on my pro master 2500. Well worth it

2018 Ram ProMaster 3500

Relatives easy to install. The handling has become more stable with less lean since I’ve installed these springs on my RV. Very happy with the purchase.


Product is as described. I will post an update as soon as a pop them in and roll with them for a while.


We installed the rears first and the difference was impressive. Going to install fronts tomorrow.


Thank you very much. I got my order. Perfect service. Alex. Calgary.


A noticable improvement in the ride. Very happy with them.


Better handling/ Highly recommend


2021 Ram ProMaster 3500

Easy to install, Ill put some miles on them and update.

  • Front Suspension SumoSprings To Reduce Sag On a 2006 Chevrolet Impala
    First I recommend checking your struts and springs to see if there is any way to adjust the preload tension or compression dampening on them for your 2006 Chevrolet Impala SS. If the settings are adjustable this will help you to dial in your ride quality to where you would like it to be. If you do not have adjustability on your struts the Coil SumoSprings Custom Helper Springs # CSS-1195F will help to absorb some of the sag that you are experiencing. The progressive construction of these...

  • Recommended Suspension Improvement for a Jeep Wrangler When Towing a Trailer
    Both the Timbren # TJRJK and the SumoSprings # CSS-1195R will help with sag and stability while towing. However, they will affect the ride when no towing as well. The Firestone Coil-Rite Air Helper Springs # F4173 are adjustable from 35 psi all the way down to 5 psi. This will give them up to 1,000 pounds of load-leveling capacity when filled, and then feel basically nonexistent when deflated. If you are still getting a lot of body roll when towing, or even when not towing, the SumoSprings...

  • Suspension Enhancement for Front and Rear of 2018 Ram ProMaster 3500
    Since your 2018 Ram Promaster 3500 has coil springs in front you'd need the # CSS-1195F for the front and then for the rear # SSR-313-54 like what you referenced.

  • 2018 Promaster 2500 SumoSpring Recommendation
    For your 2018 Ram ProMaster 2500 the SumoSprings rear suspension kit you'll need is the part # SSR-313-54. This has the most support at 2,800 lbs which will be ideal since you will be converting your setup to a camper. I'd first try it with both spacers. If you find the ride quality is too harsh then maybe take the one out, but I would be shocked if you didn't prefer the spacers. The springs are most likely going to touch all of the time due to the additional weight you are adding.

  • Recommended Suspension Enhancement For a 2018 Ford Transit 350HD Camper Van
    For your 2018 camper van on the Ford Transit 350HD having the dual wheel wheels I recommend installing the SumoSprings Solo Custom Helper Springs # SSR-121-54. These will help to reduce the rear end sag and increase stability around turns. The Firestone # F53ZR and other air spring products we carry are not compatible with your dual rear wheels. You can also add the Coil SumoSprings # CSS-1195F to your front suspension. These will also help increase stability when turning while also helping...

  • Do Front and Rear SumoSprings Need to be Installed on 2018 Ram ProMaster 2500 Near GVWR
    Since you are loading your 2018 Ram ProMaster 2500 up to the GVWR I recommend starting off using the SumoSprings Solo Custom Helper Springs # SSR-313-54 for the rear axle. These are the heaviest duty option available which is what you need for your application. If you had a passenger vehicle then I would say that the rear SumoSprings would be enough but since you have an RV I also recommend installing the Coil SumoSprings Custom Helper Springs # CSS-1195F. These will not only assist your...

  • SumoSprings and Sway Bar For a Thor Compass On 2018 Ford Transit 350HD Chassis
    Yes, I always prefer to also install the Front # CSS-1195F with the Rear # SSR-121-54 SumoSprings on your Thor Compass with the 2018 Ford Transit 350 HD chassis. The combination will greatly improve your ride quality and reduce the amount of sag the chassis will have due to the additional weight. We do offer the Hellwig Adjustable Rear Anti-Sway Bar # HE44YR for your Transit chassis. This is the only currently available sway bar I can find. The 1-3/8" chromoly steel bar is going to be...

  • Recommended Sumo Springs For A 2019 Hymer Aktiv Motorhome
    I can certainly point you in the right direction. For the rear axle of your 2019 Hymer Aktiv Motorhome, I recommend the SumoSprings # SSR-313-54. These are the 2,800 lb capacity jounce springs. They will replace the factory bump stops and do a great job of leveling your ride, and absorbing shock. For the front axle, we do not carry any jounce springs, but you can use the SumoSpring coil helpers # CSS-1195F. This is an insert that goes on the factory coil springs. This will help add support...

  • Recommended Suspension Upgrade for a 2021 Ram ProMaster 3500
    Yes, you should add the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension item # CSS-1195F to the front suspension on your 2021 Ram ProMaster 3500. These helper springs adjusts progressively to the weight of your load. I have linked a review video below. As far as your air lift system goes for the rear end, I recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers item # AL88233. This system includes a jounce bumper that will stop...

  • Suspension Enhancement For a Smoother Ride On a 2022 Coachmen Nova 20C Class B Motorhome
    There are a few different SumoSprings for the rear of your 2022 Coachmen Nova 20C. If you have the lightest 1,000LB # SSR-313-40 springs on your Nova these are not going to provide enough support for all the additional weight added to you camper. A better option would be the 1,500LB # SSR-313-47 or 2,800LB # SSR-313-54 depending on how much cargo you are carrying or towing. Please let me know what you have and the types of loads you are carrying and I can help you determine if there is...
