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.

Video Transcript for SumoSprings Maxim Rear Helper Springs Review

Speaker 1: Today we're gonna be taking a look at SumoSprings Maxim Custom Helper Springs for the rear axle. You'll want to use our fit guide to verify, which one are the correct ones for your vehicle, and this is what our springs will look like when it's installed. It's got a mouth connected between the upper bracket connected to the frame and the lower bracket connected to our leaf spring.So when going over potholes or uneven terrain it's gonna absorb some of that shock, so it won't it transfer into the body giving you an overall smoother ride.Additionally, when you load down your vehicle, this is gonna help provide some cushion, and help keep your vehicle at it factory ride height when loaded down. This is gonna help keep your suspension at the correct geometries since it's closer to the factory ride height. So even while loaded down, you're not gonna get as bad of tire wear as you we're before. Helping to increase the life of your tires and your suspension components.Before we install our SumoSprings we'll take our motor home out on our test course and we'll see how it drives now.

I can already tell when turning even slightly the motor home wants to rock to the right. And as we go over the bumps it really starts to sway back and forth. This throwing you around is going to cause fatigue as you're going down the road. You're trying to maintain your self steady in your seat and control your vehicle. It's gonna leave you exhausted once you get to your destination and as I go through this longer turn I can really feel the RV staying out to the outside.

It doesn't want to spring back and become level. It keeps you hanging you hanging off on one side. Once you straighten it back out it really sways back and forth as it tries to return to that level center.And now with our SumoSprings installed we'll head back out on our test course. And even turning right into the test course I can feel our RV is staying straighter than it was before. And when going over the bumps I can feel that it's easier to hold on to my wheel and maintain straight line.

It's not jostling me back and forth nearly as much in the wheel or my seat. So overall I'm more comfortable and I can already tell it's easier to drive. So on those long distance road trips I won't have worry about being so fatigued when I get there.And now on that long turn I don't feel like a roller coaster going around the edge. It's much more straight up and down. I just feel like I can relax as I drive.At 50% compression it offers 2,600 of load carrying capacity.

Now this isn't additional load carrying capacity above your vehicles weight carrying capacity, it just helps support it. It's made of a durable micro cellular urethane, with operating temperatures of -25 degrees fahrenheit, up to 200 degrees fahrenheit and it's resistance against damage caused by oils, road salts, and UV rays.So when comparing these to your factory Jounce Bumper it's gonna provide more cushion, as there is always contact between the leaf spring and the frame with your SumoSpring, where as your Jounce Bumper has a gap and it only applies if you're near bottoming out your suspension.And, when comparing them to airbags, the SumoSprings are gonna be a lot less maintenance and they're gonna be a set and forget. They're always gonna be installed, doing their thing. Where as airbags are gonna change in pressure depending on the temperature of where you're at, so you're constantly have to adjust those pressures to maintain that proper ride height and load carrying capacity. Additionally airbags can leak down if there are any leaks with those systems, you can lose that. Where SumoSprings don't have any air in them. So they're always gonna be there. They're gonna be more reliable in ready to go. One of the benefits of airbags is that you are able to adjust them independently from side to side to help better compensate for uneven loads. You can also adjust the air pressure to an extreme of very high or an extreme of very low to match your load to match your load whether it be completely unloaded or loaded down as much as you needed it to be.And that completes our look at SumoSprings Maxim line of Custom Helper Springs for the rear axle.

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. 649728

I purchased the SumoSprings Maxim rear axle helper springs for my 2016 F-53 Ford Chassis Georgetown 270S last year. They arrived quickly and were relatively easy to install. We drive in the mountains and regularly contend with cross-winds and some uneven road surfaces. we have put on a couple thousand miles since I installed these and the improvement is noticeable. These helper springs really smoothed out the ride, made the RV much more stable on the road with no harshness in ride comfort. These springs are worth getting if you are trying to avoid that side to side rocking and soft feel of the stock springs. I plan to install a set on the front soon to further add to the stability in windy conditions. These springs are a worthwhile investment and not that pricey compared to other options. 492088

Installation of the rear SumoSprings Maxim Custom Helper Springs was accomplished without any problems. All necessary parts to install the springs were supplied in the kit. The SumoSprings have made a great difference in the ride and stability of our 2015 Thor ACE. The ACE ride and sway has improved to the point it is like driving a new RV. The side winds that push on the rear do not make the front want to move toward the center line or road side. I don't feel like I'm in a constant battle to stay in my lane which will vastly improve my driving pleasure. Passing 18 wheeler trucks didn't make our rig move away like before. I feel much safer with this more stable drive. The RV also doesn't seem to have the top heavy sway as we corner we actually have a much safer and smooth transition. Our test drive home from the shop was about 22 miles, with 5 miles on 4 lane and 18 miles on a narrow two lane back road. I feel this gave me the chance to evaluate the improved performance gained by installing the SumoSprings. I know our next trip will be a much safer and pleasant drive Thanks to the SumoSprings. 611841

Big Improvement! Installed Sumosprings on Rear Thor ACE 29.4 F53, after installing Sumosprings on front and steering stabilizer shock. The rear SumoSprings greatly eliminated sway from back of MH, and seemed to firm up the ride and a reduce bounce. The improvement was very noticeable but incremental compared to the modification to front of coach. Was a VERY good investment, but suggest start with front Sumosprings, With all 3 modifications I can drive down the road with two fingers (not recommended) on steering wheel, no fear from wind/trucks, and pleasurable ride! NOTE: Bolts were too long (5" needed 4" otherwise interfered with break line), etrailer probably would have quickly replaced but in hurry and purchased myself ($2). 561329

I read a lot about the sway u get from a Rv and how people buy everything under the sun to fix it. I decided to purchase the sumo springs first before any sway bars shocks or any other product people had purchase. They cured all of the problems I was having with the pushing from a semi passing and the wind. I went from a death grip on the steering wheel to a more relaxing ride. I live in the Columbia gorge and we get some heavy winds. So glad I bought them I would recommend these to anyone who would like a more stable ride and and a relaxing drive. 681788

Item installed easily. Ideally I would have removed the tires but with some effort this item installed without the removal. Springs definitely tighten up the vehicle rear end. I have not placed load on yet so the real test is yet to come but handling has improved. ETrailer is a great company to do business with. Will use again and again! 516503

First time using etrailor. Very satisfied. Very helpful customer service when ordering. Item received quickly and with all parts. Had the SumoSprings installed ... Wow! Huge difference in my ride, a 31 ft Winnebago. Stable, and much easier to steer. Seems to have quieted down much of the rattling, probably because of the much sturdier ride. Extremely satisfied, and highly recommend. 715353

Purchased these SumoSpings from etrailer.com who where fantastic, helpful, and friendly throughout this transaction. Can't say enough about how they did everything they could to ensure the purchase and shipping of the product took place in a timely manner. The SumoSprings themselves are great, truly smooths out the ride, increases the stability, and reduces the amount of road jarring that takes place with our 2016 Jayco Precept. The installation is easy enough that most anyone can do it. Although they do leave out a couple of important things to note/steps to take, but most anyone with a little common sense can figure it out. Well worth the investment. 527317

I really appreciate the difference the springs have made in the handling of my motor home. Before them I worried about bottoming out and loosing control getting on and off bridges and overpasses. Now my trips are more relaxed. Having the right parts delivered the first time also was really appreciated. Thanks again.

Already had front sumos and my thought on them is lukewarm. I installed the rears and test drove it yesterday. Wow, what a difference when turning corners and entering/exiting driveways with a lip on them. No more rolling from side to side. My wife rode along on the test drive and also felt the difference almost immediately. It just feels stable. I highly recommend this product. Did the install myself in about 2 hours without pulling the wheels, just make sure you have a good right angle drill for the bottom rear holes. 547447

  • Recommended Components To Improve Handling of 2017 F53 Chassis Motorhome with GVWR of 18,000
    The best way to adjust handling on your 2017 Ford F53 18K chassis is to start with anti-sway bars. I recommend starting in the back with the Roadmaster Rear Anti-Sway Bar for Motorhomes # RM-1139-146. Then I recommend the Roadmaster Front Anti-Sway Bar # RM-1139-140. These will help the handling by reducing body roll and diminishing the effects of crosswinds and shifting cargo by balancing the weight transfer.

For the front, I recommend using the Roadmaster Front Anti-Sway Bar for Motorhomes # RM-1139-140 if your chassis is up to 16,000 lbs, but if it is 18,000 then use the Roadmaster TruTrac Front-Axle Trac Rod # RM-TRAC-F550.

  • Recommended Suspension Enhancement For 2017 Thor ACE On Ford F-53 Chassis
    The SumoSprings are designed to help with the issue you said you have. I recommend installing the front and rear to make sure the entire motorhome is supported. The springs you need for the front are part # SSF-170-40-2, and the springs for the rear are part # SSR-187-40-1. These will help cushion the ride and since they work independently, they will help keep the motorhome level even though one side has a slideout.

  • Will the SumoSprings Helper Springs Raise the Height on a 2016 FR3 with a Ford F-53 Chassis
    The SumoSprings Helper Springs typically don't raised the height of the vehicle they are installed on. They are designed to offer help when the vehicle is swaying or under a load in which case they basically just cause resistance. The reason I said that they typically do not raise the height is because if the suspension is in bad shape they have been known to help the suspension out and raise the vehicle a little.

These springs are made for models ranging from 16,000 to 22,000 lbs. These springs will mount both on top and bottom but are not connected. They will absorb the road shock, but will also allow full axle movement so you will have the best steering ability and traction.

  • Comparing Timbren and SumoSprings Suspension Enhancement for 2019 Thor ACE 30.2 Motorhome
    The biggest difference between the two for your 2019 Thor ACE 30.2 motorhome, and the reason why I highly recommend the SumoSprings over the Timbren, is what each product is constructed from. The Timbrens are made from a strong, rigid rubber while the SumoSprings are made from microcellular urethane. This is important because it means the SumoSprings will compress more gently, while the Timbrens are known to give a much stiffer ride. The front axle and rear axle fits for your 2019 Thor...

  • Choosing Between SumoSprings or Timbren for 2013 Fleetwood Storm 32BH

Neither of these options will come into play unless the factory suspension gets compressed. If ride quality is the more important consideration, the Sumo Springs option is what I'd recommend as they' give a more supple ride. If reducing roll in the corners is foremost in your mind,...
