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.

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 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

Before installing the Sumo Springs my motor home had a dangerous sway and would bottom out going on and off bridges and over passes. After installation, I have much better control of the vehicle. Sumo Springs have made my vehicle a much more comfortable vehicle to drive. 328631


Comments

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.

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.

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

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

The springs look great. I went to install them today, and was a bit disappointed to find that my W22 is not as depicted in the instructions. I will take it to a shop to have them installed. I am still looking forward to feeling the difference in the ride and handling. I can only give a 4 star rating at this stage and that is based on the service and delivery from etrailer. They are always good. 581594

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

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

2019 Thor Outlaw 29J I've only driven this RV for about 1800 miles. I don't know if I could rate these any higher. I ordered both the front and rear Sumosprings and the fronts arrived earlier than the rear, so I went ahead and installed them and went for a 100 mile test drive. Night and day difference, no more harsh ride in the front, and a lot less pogoing. Now I can't wait until the rears come in and I can test those. 539764

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

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

I had the both the front and rear sumo Springs installed on my 2016 Newmar Canyon Star, by the crew at Etrailer. The improvement in the handling was noticeable the minute I hit the road. The most noticeable effect was the reduction in the top heavy sway when cornering. It also seems to have reduced the effect of passing semi's . I would definitely recommend this product to anyone who has a Ford F53 chassis on their motorhome. 661101

  • 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. For that you would want...

  • SumoSprings for a 2018 Forest River FR3 29DS 18000 lb GVWR on a Ford F-53 Chassis
  • 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. You can also install Front # RM-1139-140 and Rear # RM-1139-146...

  • Best Way to Reduce Sway and Body Roll on 2019 Winnebago Intent Built on Ford F-53 Chassis
  • 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. For your motor home the...

  • 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...

  • 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...

  • 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 Anti-Sway Bar and Steering Stabilizer for 2015 F53 Chassis Motorhome
  • 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...

  • SumoSpring Recommendation for 2018 Winnebago Intent 26M
  • To help smooth out a jarring ride quality on Ford F-53 motorhomes the best option is to go with a SumoSpring set like the part # SSR-184-40-1 which is designed to cushion bumps as well as help reduce sway. For the front you'd then want the # SSF-170-40-2.

  • Is Drilling Required to Install SumoSprings on 2018 Winnebago Sunstar 31BE
  • The correct SumoSprings Custom Helper Springs for your 2018 Winnebago Sunstar 31BE (that features an 18,000 pound GVWR), which is the part # SSF-170-40-2 for the front axle and # SSR-184-40-1 for the rear axle, will not require any drilling during installation. These are complete bolt-on applications that will simply replace the factory bump stops on the Ford F-53 chassis. I have attached a couple short video demonstrations along with the written installation manuals for these kits...

  • Recommended SumoSprings Suspension Enhancement for 2015 Itasca Sunstar 27N on Ford F-53 Chassis
  • For your 2015 Itasca Sunstar 27N, I recommend the SumoSprings Maxim Custom Helper Springs - Rear Axle # SSR-184-40-1. These springs are a confirmed fit for your vehicle and will give you 3,000 lbs capacity at 50% compression. These springs will compress as much as 80 percent and will progressively help with the load as needed. The greatest help when using these springs is the support as they work independently for off-center loads and stability to reduce body roll. For the front,...

  • SuperSprings Jounce Spring Kits for Front and Rear Axles of 2016 RF-53 Winnebago Motorhome
  • Your 2016 Winnebago Vista LX is indeed built on the Ford F-53 V-10 chassis. 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. I linked the part of the online document with this information that I found on their website. The SuperSprings front-axle jounce spring kit for the 2WD model is # SSF-170-40-2 which works for GVWRs from 16K to 22K. This is the...

  • Both the SumoSprings Helper Springs, # SSR-184-40-1 and # SSR-187-40-1, are confirmed to fit the F-53 Ford Chassis of your 2016 Thor Ace RV. The difference between the two sets of helper springs is the # SSR-184-40-1 helper springs has a weigh capacity of 3,000 lbs at 50 percent compression, while the # SSR-187-40-1 springs have a 2,600 lbs capacity. Other than the weight capacity difference, both of these helper springs sets are identical in construction and installation. I have...

We don't have a list of local shops for you to use for the install, but if you find a local RV shop they'll have a garage for projects like this that would easily take care of it.

Since this is the case the correct SumoSprings for your front axle is part # SSF-170-40-2. Attached is an installation video of these being installed on a 2018 F-53 chassis that you can reference.

  • SumoSprings or Air Bags for 2016 Jayco RV on Ford F-53 Chassis
  • 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...

For your rear axle you need the SumoSprings Maxim # SSR-184-40-1. These springs will support your Forest River's suspension and absorb the shock that an RV can encounter; they will also minimize the amount of sway you experience. The springs will compress according to the weight of your cargo and work...

Front: SumoSprings Rebel Custom Helper Springs part # SSF-170-40-2 (16,000 and 22,000 lbs) SumoSprings Rebel Custom Helper Springs part # SSF-173-40-2 (24,000 and 26,000 lbs) Rear: SumoSprings Maxim Custom Helper Springs part # SSR-184-40-1 (16,000 and 18,000 lbs) SumoSprings...

  • 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.

  • SumoSprings Recommendation for 2017 Winnebago Vista 32YE
  • When picking out a set of SumoSprings to fit a motorhome you have to go by the kits that fit the chassis of the vehicle as well as fall under the same GVWR range too so that you get the correct amount of support. Also you want to keep in mind that SumoSprings has a few different lines of springs too. I looked up your Winnebago Vista 32YE and it has an 18k GVWR. So the # SSR-187-54-1 would be rated too high since it's for 20 to 26k motorhomes. So you'd want the part # SSR-184-40-1 for...
