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 Installation - 2017 Ford F-53

Today on our 2017 Ford F53 Chassis Motorhome, we're gonna be taking a look at, and showing you how to install, the SumoSprings Maxim Custom Helper Springs for the rear axle.Having a motorhome can be a great thing. We can take trips with our family and see a lot of places that we could never see before. But one thing that a lot of people don't talk about and don't think about is the suspension and how their motorhome is going to drive.Here at etrailer.com, we see a lot of the issues of customers coming in complaining that their motorhome feels like it's rolling, it's got a lot of body roll, and just not all that stable going down the road. And we can see in our motorhome, there's quite a bit of space for wind to catch the side. We're basically driving a giant windscreen going down the highway. So we're fighting that wind, pushing the steering wheel back and forth, which eventually can get very tiring and not very much fun once we get to our location.So we're gonna take our motorhome out on our test course and see how it handles before we put our suspension upgrades on.As I'm driving through our bump course here, I can definitely feel each time I hit a bump, whether it's a solid bump and the front end's coming up and coming back down and bouncing really hard, or if it's alternating bumps to where we're getting a lot of body roll back and forth.

It really just doesn't feel very solid or planted on the ground.Now, as I come up to the slalom course and I'm going in and out of turns, I can really feel the body roll every time I make a turn. It almost feels like my motorhome wants to lean before it actually starts reacting. And with the wind today, I'm definitely fighting the steering wheel trying to get it back to center.So here's what our SumoSprings are gonna look like once we have them installed. These are gonna greatly reduce the amount of driver fatigue we have, and give us that nice, smooth, comfortable ride when we're driving down the road. And our rear springs are gonna do that by supporting the weight of our motorhome in between the inaudible 00:01:54 spring and the frame here.Now each one of our springs are gonna be made out of a microcellular urethane, so they're gonna resist most inaudible 00:02:02 chemicals like oil, road salt, and UV rays, so I know they're gonna last a long time.

And on the back of our motorhome, typically, a lot of them are gonna have a bathroom or a bedroom towards the back. That can add a lot of weight to the rear axle. And since we're asking our rear axle and suspension to support not only the motorhome but all that extra weight, it's gonna put a lot of strain and stress.Our SumoSprings are gonna take some of the strain and stress off of our factory suspension, because it's gonna help support that load. And it is gonna help absorb road shock so we'll have a nice, smooth ride.And our SumoSprings are gonna provide a progressive load control, so the more we load them down, the stiffer they're gonna become. And the lighter the load, the springs are gonna press easily for a soft engagement, and a less bumpy ride.And whenever the springs do compress, they can compress up to 80%.

But the way they're designed is is they're gonna compress vertically, and they're not gonna expand out to the side, so we're not gonna have to worry about any other components. 'Cause once we have our tire back in place, it will be pretty close, but we're not gonna have to worry about it coming in contact. And whenever we're not loaded down, our springs are gonna be able to extend up to 50% of their normal height. So we don't have to worry about any kind of limitations when it comes to our suspension travel. We'll have plenty of compression and rebound.And since we're gonna have one spring on each side, they are gonna work independently from each other, so if we take a turn and this one compresses down, the other one is gonna extend up so it can handle that extra load.

Or if we have an uneven load that's in our motorhome.Our helper springs are gonna have a weight capacity of 3000 pounds. Now, keep in mind, they're not meant to increase the payload of your motorhome. They're just there to help support that extra weight.They are gonna come with everything you need to get it installed, and we are just gonna have to drill a few holes to build everything up.One of my favorite things about these springs, though, is that once we have them installed, they're gonna be completely maintenance-free. We're not gonna have to worry about air lines or monitoring air pressure like we do with airbags.So now that we have everything installed, we're gonna take our motorhome back out on the test course and see how it handles.Now as I'm driving over our bumps course, I can immediately feel a lot of difference. Don't get me wrong, there's still a little bit of roll, just naturally that's gonna happen, but it's a lot more stable and it feels a lot more controlled, and the rebound isn't having the motorhome go up as high. And even on the solid speed bumps, it just feels like it's genuinely handling a little bit better, and handling the bumps better.And as I continue down to our slalom course, going in and out of the turns, it definitely feels a lot more stable. There's not as much body roll. It doesn't feel like a sports car, but it definitely is a lot more stable, and I have a lot more confidence driving through the course.To begin our installation, we want to lift up the rear end of our motorhome. You wanna make sure you're lifting it by the frame and that it's supported so that the suspension can hang down. We'll go ahead and remove our tires so we can have room to work right in this area.Now we can start assembling our spring. So we'll grab the spring out of the box along with the upper bracket, and on the top of the spring we're gonna have four holes that are pre-threaded. Two of these are gonna line up with two of the holes in the top of our bracket. So we wanna make sure this little lip is facing up whenever we place it on top, and line up the holes.And we're gonna grab two of our 3/8ths flange bolts, and we'll get them started by hand, making sure they thread in. And come back with a 9/16th socket and tighten those up.Now we're gonna take our assembly and we're gonna flip it upside down. We're gonna have one threaded hole in the bottom, and then I'm gonna go ahead and grab our lower bracket. Now, there's gonna be a notch right here, and a hook. The notch needs to go towards the front of our motorhome, and the hook needs to go towards the back. So we'll lay it on top of our spring . again, grab one of those 3/8ths flange bolts, get it started by hand, and tighten it up with the 9/16ths. That way, when we put it in place, we know that that notch is gonna be towards the front, 'cause this is gonna sit directly against the frame.So now we're gonna take our entire spring assembly and that hook right here is gonna land right on the inside of our front U-bolt. And then the notch in the front is gonna go around our leaf springs.Now on our lower bracket, you'll notice that we're gonna have a square hole that's gonna be on the outside of our leaf springs as well as on the inside of the leaf spring. We're gonna grab two of our carriage bolts, and we're gonna drop them down. And since the spring is already in there, it may take a little bit of wiggling around to get the bolt to drop down through. We'll make sure our spring's back in the position it's supposed to sit, and we're gonna grab the lower clamp.You'll notice it's gonna be kind of a U shape. You want the flat section to go up against the bottom of the leaf spring, and we'll drop our bolts down through the two holes. And because of where our brake caliper is, you wanna make sure that that notch right here is on the side by our brake caliper. And we're gonna secure it down with two 3/8ths flange nuts. So for now, we'll just get them loosely started. That way we know the bracket won't fall down and the spring will help keep it in place.Then I come back with the 9/16ths socket and I'm gonna tighten up my two carriage bolts. Now when you're tightening those up, you wanna alternate going back and forth so it has an even clamping force as it draws it up.inaudible 00:08:23 the lower half in a secure position and it's not going anywhere. The top half can still move. But we're gonna need to make a few marks, so we're gonna come to this bottom hole on each side of our side plates, and we're gonna make a mark going across right in the center of that hole going towards the outside. We'll use that as our reference point, 'cause we're gonna get a measure on the frame here, and we need to measure it from the top down 4 1/2 inches, or measure from the bottom up 4 1/2 inches.Coming from the top of the frame, if we come to 4 1/2, I'll make a mark. We'll do that on both sides.And since our suspension is hanging because our vehicle's lifted by the frame, we're gonna need to lift the axle up until the mark we made in our side plate reaches the mark that we made on the frame. Now I'm just gonna be using a floor jack, putting it right underneath the hub and lifting up, but again, you wanna make sure the jack stands are in place and that your vehicle is safely lifted to begin with.So if you notice that one line is meeting up and the other line's above the other one, it's probably because we just need to kinda level out our spring to where it sits nice and even, and you just kinda have to play with the height adjustment until you get both lines to line up.Now I'm gonna start out with a smaller drill bit than the final size just so I can get through the frame, be a little bit easier to enlarge it. But before you start drilling, you always wanna double-check behind the frame and anywhere you're drilling so we don't drill into any lines or any electrical wires.And with our pilot hole drilled, I'm gonna come back with that final 7/16ths inch drill bit and enlarge that hole. You wanna do that for both the lower holes.Once both lower holes are drilled out, we're gonna take our 3/8ths flange bolts, we're gonna pass it through the bracket through the frame, and we'll go on the other side and we're gonna secure it down with a 3/8ths flange nut.I'm gonna come back with a 9/16ths socket and wrench, and then we're gonna tighten up the hardware, making sure everything's secure.We can go ahead and drill out the middle hole on both sides, and we'll repeat the same process with the same combination of hardware.So with the left side on, we can go ahead and repeat that same process on the passenger side, and we can put our tire back in place.That'll finish up your look at the SumoSprings Maxim Custom Helper Springs for the rear axle on our 2017 Ford F53 Chassis Motorhome.

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 ordered front and rear roadmaster sway bars, front and rear sumo springs and a Roadmaster steering stabilizer for my 2019 Winnebago Vista 29VE after I picked it up several weeks ago. The drive home was a nightmare trying to keep it on the road. I received all the parts in good shape except the rear sway bar came in with the package all beat up and only had the sway bar not any of the other needed brackets and bolts. I called etrailer and explained the situation, sent pictures of the box and they mailed ma a whole new set immediately not even waiting for UPS to pick up the original one. My son and I installed all of them in my driveway and what a difference! The RV is now sound going down the road even in cross winds and large trucks passing by. Thank you etrailer. 713882

We own a Winnebago 26HE and installed SUMO SUPER SPRINGS (item # SSR-184-40-1). The SUMO SPRINGS made a 90% improvement in handling and drivability of the vehicle. They all but eliminated the wind side push from passing semis and substantially reduced the effect of wind blowing from the side. I highly recommend this product. 673370

I did a fair amount of research on how to make my Winnebago Sunstar motorhome handle better. Cheap handling fix was one action I took. But still the motorhome had lots of rebound when traveling over bumpy roads. I decided to install Sumo springs front and rear. I installed them myself with instructions and videos from the manufacturer and etrailer.com. A trip to the coast (about 100 miles) had me smiling from ear to ear! They worked as advertised and made the drive a lot more enjoyable. I highly recommend Sumo springs and etrailer.com! 666315

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

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

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.

Review from a similar SuperSprings SumoSprings Maxim in Vehicle Suspension


I purchased a 2011 Georgetown motorhome in 2011 which uses a Ford F-53 chassis. I wish I knew better at that time. I realized that driving it was stressful and dangerous due to the body roll and micro lunges when driving rough road or windy day or curvy roads. We limited our trips to around 200 miles due to this. I had to do something. First, the rear sway bar I bolted the connecting links to the inside bolt holes and replaced the shocks. It drove much better but still some body roll and micro lunges. So I decided to take the next step. I purchased Sumosprings for the rear and front axles. They were exceedingly easy to install, worst part was drilling the frame for the rear axle. I have now been on a trip on mountain roads for two weeks. The micro lunges seem to be gone, almost like driving a car. The body roll isn't an issue anymore, I can drive the mountain curves without feeling like being thrown over a cliff. There may be other ways to fix this Ford F-53 problem, but the Sumosprings do the job. 542019

Installed Sumo helper springs SSF-180-40-1 and ssr-186-54 on my 2014 Georgetown 328TS on a F53 chassis the springs stabilize the ride also recovers faster on rough roads and doesn't bottom out anymore . Installation time was 2 hours and 45 minutes for front and back . I would definitely recommend this product. I received the springs in three days and service was very helpful from etrailer all it took was a five minute phone call to get the right set of springs for my MH . 376115

Review from a similar SuperSprings SumoSprings Maxim in Vehicle Suspension


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

    For your 2016 Jayco RV built on the Ford F-53 chassis, I recommend going with the SumoSprings Custom Helper Springs over an air bag kit. These springs will provide you with excellent support to level your ride and minimize any sway that you are experiencing. Unlike air bags that you will have to inflate and deflate depending on your load (along with making sure they stay at the minimum inflation level during the off season), the SumoSprings can be pretty much left alone after the initial...

  • Do The SumoSprings Maxim Custom Helper Springs # SSR-184-40-1 Require Drilling For Installation
    Yes, the SumoSprings Maxim Custom Helper Springs part # SSR-184-40-1 for your 2017 Ford F-53 and will require you to drill the holes through the frame, both driver’s side and passenger’s side, using a 7/16 drill bit then secure the upper assembly to the frame by bolting the upper J-bracket to the chassis frame. This process can be seen at the 3:55 mark in the attached installation video. The installation process is fairly straightforward for someone who is mechanically inclined.

  • Best Upgrades to Improve Ride Quality/Stability of 2019 Winnebago Vista 31BE
    For RV suspension enhancement the SumoSprings are the way to go. They do the best job giving additional support that reduces sag, offering anti-sway characteristics, and also helping smooth out ride quality. Installing a second set of suspension enhancement would do more harm than good, but I do have something else that would be very helpful. See last paragraph for that. So for the rear you'd want the part # SSR-184-40-1 which is a confirmed fit and then for the front part # SSF-170-40-2...

  • Suspension Enhancement for 2019 Itasca RV Built on Ford F-53 Chassis
    For your 2019 Itasca, which was built on a 2018 Ford F-53 chassis (motorhomes are generally built on the previous model year chassis) there are a number of suspension enhancement options. You did not mention which model of Itasca you had so I will go over the options for you, which are based on the GVWR of your Itasca. If your '19 Itasca has a GVWR of either 16,000 lbs or 18,000 lbs the correct rear axle suspension enhancement is the SumoSprings Maxim Helper Springs # SSR-184-40-1. If...

    You are certainly not alone in looking for a way to reduce the amount of sway and body roll when driving a motor home but there are great solutions to remedy those white-knuckle moments when going side-by-side with a semi or meeting crosswinds. The best way to reduce the sway and enhance the ride of your 2019 Winnebago Intent 29L built on a Ford F-53 chassis is to add a rear anti-sway bar, followed by a front anti-sway bar, and after that a steering stabilizer.

    SumoSprings will definitely help to improve the ride of your 2018 Forest River FR3 29DS. For your Ford F-53 chassis with an 18,000 lb GVWR you want part # SSF-170-40-2 for the front axle and part # SSR-184-40-1 for the rear axle. The two greatest things about about the SumoSprings is that they do not require drilling for the installation and once the installation is complete there is no maintenance that needs to be done.

  • Sway Bars and SumoSprings for 2018 Winnebago 26 Intent Ford F-53 Chassis
    The general consensus with the Airtabs is that they are more of a gimmick than anything else. I would not recommend them for you. If you've already installed the Roadmaster sway bars part # RM-1139-146 and # RM-1139-140 as well as a steering stabilizer the next thing I'd recommend is SumoSprings # SSF-170-40-2 for the front and # SSR-184-40-1 for the rear and you'll have your motorhome handling very nicely.

  • Recommended Jounce Springs for Two-Wheel Drive 2019 Ford F-53 Chassis
    The jounce springs I recommend for your two wheel drive 2019 Ford F-53 chassis are from SumoSprings, the SumoSprings Rebel for the front axle and SumoSprings Maxim for the rear axle. The reason why the SumoSprings are the best is because they not only work to reduce sway, but also keep your vehicle level and give you a smoother ride. The SumoSprings can do this because they are made of a microcellular urethane which compresses. Each of the springs works independently which is what is...

  • Suspension Enhancement for 2014 Fleetwood Storm 28MS on Ford F-53 Chassis
    There is a way to make the ride less jarring on your 2014 Fleetwood Storm 28MS, which was built on a 2013 Ford F-53 chassis. From my research your RV has a GVWR of 18,000 lbs, though you'll want to double check just to make certain. I recommend using Sumo Springs on both the front and rear axle, which are going to expand and compress independently of one another in order give you a much more comfortable ride. For your Ford F-53 with an 18,000 lb GVWR, the SumoSprings Rebel # SSF-170-40-2...

The four versions of this Class A motorhome have two different GVWRs, either 18K for the 27N and 30T, or 22K for the 35B and 35F. I could not find a variation with a GVWR of 24,000-lbs.

    On your 2015 Thor ACE motorhome on Ford F53 chassis, the size of the vehicle often will have the effects you mentioned. The best solution is to add Anti-sway bars and a steering stabilizer. I recommend adding the Roadmaster Rear Anti-Sway Bar for Motor Homes # RM-1139-145 first as the rear sway is what you feel the most when crosswinds and passing semi trucks come and this model is the correct fit for your vehicle weight. This system mounts to the rear axle and the frame to balance the...

  • Sway Bar and Steering Stabilizer Recommendation for 2016 Ford F-53 to Improve Ride Quality
    The biggest ride improvement you'll make on the Ford F-53 is a rear sway bar. Next you'd want to do a front sway bar and then finally a steering stabilizer. Doing all three of those will make a night and day difference. For a rear sway bar you would want the part # RM-1139-149. For a front sway bar you then would want the part # RM-1139-140 and then steering stabilizer # RM-RBK4-RSSA. If you still want more at this point then Sumosprings would be the way to go.
