Rear Suspension Support

SumoSprings helper springs are great for RVs or motor homes. Heavy rear loads can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the motor home's weight. And because there is less weight on your front axle, your front 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.


SumoSprings diagram of installation above existing vehicle spring

Each spring in this kit is bolted to two mounting brackets. One bracket is attached to the frame of your vehicle, and the other bracket is attached to the axle, typically above your existing factory leaf spring. Because each helper spring is in full contact at the top and bottom of the suspension's travel, the expanding and contracting action of the SumoSprings enhances your ride under all conditions, not just when it's loaded. And the closed-cell urethane springs act like a shock absorber to dampen road vibration.


SumoSprings compressing under load

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 springs can also compress by as much as 80 percent to support a heavy rear 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 front 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.


SumoSprings expanding to allow play in the suspension

These springs extend in height by as much as 50 percent to allow more movement in your suspension when you're traveling unloaded, making your ride smoother and more comfortable.


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 expand and 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.


This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

Review from a similar SumoSprings Maxim in Vehicle Suspension


The springs them selves are great but I just had to replace all the mounting bolts to frame and straighten the bracket as 7 out of 8 bolts broke, 1 bent and subsequently bent the bracket. I just emailed sumo springs and so far they don't care.

Review from a similar SumoSprings Maxim in Vehicle Suspension


I watched the install video probably three or four times before these arrived at the house. I went ahead and removed my wheels just like the install video. Everything went smoothly. I took our Fleetwood Flair 32s on a test drive and I was really impressed with the overall feel of our RV now.. The first thing I noticed was the fact that I’m not having to constantly correct to stay in my lane. In the past my hands were constantly moving to maintain a line. Not now.

Same review as the front springs. Recommend there springs for any coach without air ride. These took the ride of our 2022 Coachman from that of an empty dump truck to as good of ride as my Ford F-250 SuperDuty. etrailer really know the products and can help you find anything you are needing. I did not remove tires to do this project and because it does not have self leveling to pick the coach I had to work one spring at a time using jacks and jack stands.I.

Review from a similar SumoSprings Maxim in Vehicle Suspension


The installation is more difficult than the installation lead me to think it would be but once installed the sumo springs contributed greatly to dampening the roll of the RV as it went through ruts and over speed bumps etc. I am a little surprised at how compressed they are after I let the vehicle down on them and I'd appreciate knowing if others have this level of compression. I had considered a 2cm lift for this vehicle but held off for now. Pictures attached. First pic 4616: Shows that on my rig I had to jack the spring and axle down from the frame in order to get the sumo spring in. Second pic 2816: shows that I was able to put the sumo sprint in the left of the sway bar bracket (which had to be removed). Next I used pry bars to move it to the right into the bracket where it belongs. Third pic 5748: shows the spring installed and compressed by the vehicles weight. Fourth pic 2230: Shows the spring partially installed on the left side. Note that the eyelet on the sway bar bracket on this side (sprinter 3500) makes the install much harder and I had to really jack the springs down to get it on this side. Fifth pic 0054: Left side installed and sway bar reinstalled. Still unloaded

Review from a similar SumoSprings Maxim in Vehicle Suspension


We ordered the sumo springs for our 2004 coachmen freedom series. The order came in just a few days as they did when we bought a heavy duty rear stabalizer last year. While I waited for the order ,myself and a grandson put the rear of our rv up on 7500 lb jack stands, two would have been fine but I wanted two more just in case. We took the rear duals off to make the installation easier ,and it was. Instalation went well,only having to move the gas line on passenger side up an inch by moving a clamp.We hoped these would help the light steering issue and related pushing from side when we would get passed on freeway. Not only did it clear up these issues but also quieted the coach down some. All my tests where done at highway speeds with the towed car behind. Thank you again to all at etrailer! Don. Ps. Had issue loading pics will update another time


Comments
A year on the sumo springs. The springs are holding up quite well. There were 2 travel days where the wind was gusting to 20mph ,quite a bit gained in stability. Sure ...you still notice the harder gusts but it is much easier to handle. I just finished lifting the back end up to inspect the sumo springs and everything was tight and free of rub marks. I want to thank etrailer again for good instructions on these and for answering concerns I had!

Review from a similar SumoSprings Maxim in Vehicle Suspension


Our 28 foot Ford chassis Class A handles like flying a kite with no string. It needed help. I started with the Sumo springs because the description made it sound like I could do them myself. Yep. Job accomplished. Then, I purchased a front sway bar, which did not come with my motorhome. Got ready for the job and discovered Sumo springs are incompatible with mounting a front sway bar. Had I known… By the way, we are still flying our kite and having a ball. 15 states and 16,000 happy miles. But it could be better.

Review from a similar SumoSprings Maxim in Vehicle Suspension


Eliminates a lot of sway from passing semi-trucks and strong side winds, gives a truer sense of driver input and what is happening on the road, feels more solid when you setup for camping- less rocking when you walk from one side of the motorhome to the other or using the steps. Doesn't soften the ride one bit on the Ford frame. It does porpose on uneven pavment like bridge abutments' you have to keep an eye out and slow down. As long as I drive in Florida it's not a problem. would like to fix it. but not worth ripping everything out and starting over!


Comments
Thank you for your review. These are generally a simple install and I am not sure why these would not soften the ride. If you have not done anything to the front axle, it could be worth considering.

Review from a similar SumoSprings Maxim in Vehicle Suspension


They’re asking me for a review the day after I received these items. I can only give it 3 stars because I could only install the fronts today as there was no hardware in the box for the rears. I immediately opened the boxes and called. A very nice person explained how backed up they were and it would be 3-4 days before a request could even be submitted for new mounting hardware. We can only see. I’m hoping I can revise this rating later if I get the hardware in a reasonable timeframe. To be fair the box was retaped. Well never know if it was UPS or the original packer. I’m Most likely going to be leaving on my next trip with only fronts installed. They weren’t bad to install. Between the written directions and the [online video]. The only thing left out is I raised and lowered the unit to be sure the pieces were lined up before tightening. It’s really the only way.

While is was a bit of a struggle to get to the bolt location, I am glad I installed these SumoSprings Maxim Custom Helper Springs - Rear Axle. Overall, these help to make the RV ride quite a bit more stable and bounce less. The more stable ride allows to drive around corners a bit faster and with less sway.

I am sure these are very good, the only reason for the low rating is to get attention so no one makes the same mistake like i did. These DONOT FIT on a 2018 Jayco Greyhawk equipped with the JRide suspension. The Heliwig helper springs are in the way. etrailer application guide needs to be updated, the picture attached show the Heliwigs are in the way.

the rear installation was very challenging as the rv mfg had a body crossmember with a vertical attachment welded to the frame at the exact spot that the sumo spring frame bracket needed to be mounted. i had to get a little creative to overcome this obstacle but i got it done. seems to work fine . the real test will be when i hook my 8000 pound trailer to it

My THOR motor coach has the Ford F-53 chassis. I rides like a truck. That should not be surprising as "it is a truck." I purchased and installed these Sumo Springs and even though it will never be "air bag" suspension, the Sumo Spring made a wonderful difference in improving the ride. I would recommend this add on to everyone and as I meet similar motor coaches on the road, I show them the Sumo Springs and I do recommend them.

  • Suspension Enhancement to Reduce Sag and Roll on a 2000 Hurricane Motorhome Ford F53 Chassis
    First, if your RV is sagging because the suspension is worn, you will need to have the suspension fixed before adding springs. Suspension enhancement systems are designed to be installed on a vehicle with suspension that is in good working order. Once you are sure your suspension is in good working order I recommend using a system with a higher capacity. For a higher capacity system, 16K to 22K, use # SSR-181-54-1. This system will reduce sag and help reduce side to side roll. Using...
