Front Suspension Support

SumoSprings helper springs are great for RVs or motor homes that have slide-outs. Slide-out rooms and other heavy front loads can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear 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 Rebel installed showing separation of 2-piece springs

The innovative 2-piece design of these Rebel springs allows for unlimited suspension travel. This means that there will be more movement in your suspension when you're unloaded or off-roading, which makes your ride smoother and more comfortable.


Each spring has 2 pieces. One piece attaches to the frame of your vehicle. And the other piece attaches to the axle. The pieces come together to provide support when you are carrying a heavy front load. When you're unloaded, they separate so that they don't restrict the movement of your suspension. The closed-cell urethane springs also 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 front 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 rear 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.


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 Rebel Front Axle Helper Springs Review

Speaker 1: Today we're going to be taking a look at SumoSprings line of rebel custom helper springs for the front axle. Please refer to our fit guide to find the appropriate springs for your vehicle. Speaker 2: This will provide an extra layer of cushion between your suspension and your frame; and that'll help take some of the load off of your suspension parts, increasing the lifespan of your suspension components. This additional dampening force here in the front will help give you a smoother ride by absorbing some of the impacts from the road - from pot holes and other uneven terrain - and what this means for you is that it's going to help lower driver fatigue because you're not gonna have so much shock transfer up into the steering wheel.Additionally, when you have your vehicle loaded down this is also gonna help maintain factory ride height. It's gonna provide some additional force between the frame and the suspension to keep it from sagging too low. So that will help reduce that sag.

Before we install our SumoSprings, we'll take our motor home out on our test course and we'll see how it drive 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 gonna cause fatigue as you're going down the road. If you're trying to maintain yourself steady in your seat, and control of 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 - doesn't want to spring back and become level.

It keeps ya 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 onto my wheel and maintain a straight line. It's not jostling me back and forth nearly as much in the wheel or in 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 to 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, and I just feel like I can relax as I drive. Speaker 2: The springs work independently from each other to compensate for off-center loads and reduce body roll. This is particularly useful during sharp turns. They offer a 2600 pound load carrying capacity, now this does not increase the load carrying capacity of your vehicle - just how much that it can help support. It's made of a durable micro-cellular urethane that works at an operating temperature of -25 degrees fahrenheit, up to 200 degrees fahrenheit.

And it is resistant against damage caused by oils, road salt, and UV rays. Speaker 4: When comparing your SumoSprings to your factory jounce bumpers, these are going to provide cushion all the time - cause there's always contact between the spring and the frame - whereas your factory jounce bumper only comes into play when the suspension is near bottoming out. And when comparing it to airbags, these Sumospings are going to be much less maintenance. They're always gonna be in place, and they're always gonna be doing their thing.Your airbags, while they're always in place, have variables because depending on the pressure they're going to provide more or less cushion. Where our SumoSprings is gonna be proportional all the time. Additionally, there's more maintenance involved with airbags, because air can change over time with temperature - it'll decrease in colder climates, and it'll increase in hotter climates. So if you're in an area where temperature and humidity varies greatly you may have to adjust this to maintain that same ride height and comfort. And you can also have leaks on an air system, where SumoSprings you don't have to worry about that.The one main benefit of having airbags over the SumoSprings is that you can adjust it side to side, so you can really get those uneven loads compensated to bring you vehicle back to level. And you can also adjust the air pressure to match your load, so if you have a real light load you can reduce that air pressure. If you got a real heavy load you can air 'em up just to makes sure that it's exactly the same each time. Speaker 1: And that completes our look at SumoSprings line of rebel custom helper springs for the front axle.

The installation instructions for both the anti sway bar upgrade and the Sumo helper springs lacked torque values for their fasteners. Both suspension components fit correctly and have improved how our class A motorhome handles. Great service from etrailer. 556109

After a year, I’m still convinced the Sumo Springs was money well spent.

The Sumo Springs made a big difference in the handling of my 38 ft class A. I had already put Sumo Springs on the rear along with an additional rear anti-sway bar, replaced the front ant-sway bar and added a steering stabilizer. Each item made improvements but the front Sumo Springs had the most impact. So much easier to drive. Installation was very easy and the online videos were helpful. I would highly recommend these. 672241

Ordered these 2 piece Sumo springs for the front of my 2012 Itasca 30T class A. This thing rode like an old farm wagon. After installing these springs, it's like night and day. It doesn't ride like a Prevost but it rides a whole lot better than it did. If you have a short wheelbase chassis with 19.5 wheels you need these things. I won't say they were easy to install but it wasn't too bad. I'm 71 and did it in my driveway in the Florida heat in about 2.5 hours. Don't bother shopping around because etrailer has the best price and the best customer service. 526595

Preston did a great job helping me spec in the correct springs for my 2016 Thor Hurricane 27K on a F53 chassis. Placed order with him over phone and received springs two day's later. I just installed them and took Motor home on a test drive around town on bumpy streets and what a difference it made. Drives more like a truck now and less like a boat. I also installed a steering stabilizer spring and did the cheap handling fix to the sway bars. Well worth the time and effort. I did notice that the etralier installation video shows the bottom brackets of the spring installed with the "U" down which is opposite the mfg's printed instructions. I did mine according to the printed instructions cause it seemed to make more sense. Probably no big deal either way. Thanks etrailer. I'll be contacting you guys when ready to do the back end of my motor home. 649992

These made a huge difference in the drivability and handling of my 2018 Ford F53-based bounder 35K. Highly recommended. And the team at etrailer.com is super responsive and helpful. I strongly recommend this upgrade, combined with additional/reinforce sway bar. You driving will be more pleasant, less stressful and safer. - Vittorio 688201

Amazing! Installed Sumo springs on front of a new 2018 Thor 29.4. F53 frame. BEFORE was very unhappy with drive, could feel every imperfection on the road and steering was very unpredictable! AFTER: Dramatically eliminated the rough ride & steering issues . . . don't hesitate to buy these shocks you will be VERY HAPPY! My experience was so good I purchased the next week rear Sumo springs and the steering stabilize shock (much more improvements, but start with the front springs). 561311

The SumoSprings item #SSF-170-40-2, for my 2017 Georgetown GT3, with the F53 Ford chassis was very easy to order from etrailer.com and was shipped in a very timely manner. They came with easy to follow installation instruction. Be advised that you will need a 1/2" socket with a 3" extension to insert into the factory bump stop to hold bolt while removing the nut on the drivers side. This is not mentioned in the instructions. You will also need the same socket and extension to remove the bolt on the passenger side. One other note, the nut on the drivers side is a 15mm. Other than the afore mentioned 1/2" socket and the 15mm the only other tool you'll need is a 9/16". About a hour and a half to two hour job. I took the motorhome for a test drive and there is a very noticeably improvement in the ride. Very satisfied with my purchase. Thanks, sumosprings for a great product and etrailer for a great price. 566821

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. 527488

2011 Thor Motor Coach Hurricane Motorhome

When you look at the bumpstop and all the travel it can go, it makes sense to fill that space with a constant contact chusion, such as the Sumo Spring. I have a 2011 F53 chassis supporting a 32 Class A motothome. 16,000 GVW and no slide. I only installed the fronts to see how they worked. I did it myself and it took about 2 1/2 hours. If I can do it anyone that can work a wrench and understands basic mechanics can do it. I'm 60 and it's a tight space under there and takes some effort, but the jobs not hard, just doing it is hard and uncomfortable. My motorhome would ride very rough on the same roads my car ran smooth. The Sumo Springs were an improvement. They did not solve the rough ride on real poor highway, but on normal rough roads, they were an improvement that will benefit the ride on more roads than not. I now plan to do the rears when I get time. 500303

Product was delivered on time. Installed according to instructions today on my 2013 Coachman Mirada 34BH. In two hours,it was completed. Went for test drive. Wow!! What a difference in riding comfort and sway. Very satisfied. Will most definitely be buying a set for the rear next. Already have sway bars but this is "Icing on the cake" Customer service and follow up was quite good. First purchase on etrailer.com but not my last. 560749

I ordered some front sumosprings for my f53 Motorhome from etrailer. They were very helpful in taking my order, I did a price match which took more steps than I thought it should. The Sumosprings installed very easily and seems to improve the overall handling of the motorhome especially with the cornering, the coach seems much more stable and has less body roll . The only problem that I had was that the front carriage bolts on the mounts were too short but I called supersprings and the sent me the correct bolts within a day. I may have to order the rear set later. My order shipped very quickly and arrived in just a few days. Than you etrailer. 503409

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. 711826

Wow what a difference. We have had the Sumo springs in for about a year now. We have made several trips including a couple over 1500 miles and the ride and handling are so much better. The key points for us have been the smoother ride and faster recovery from dips and bumps (one porpoise and settle!). Also the improved handling at corners and turns because the rig doesn't lean as much. The big review is from my wife who was not really enjoying our class a before because the ride was making her a little sick. She is very happy now and will be the first to tell folks about the springs. As for install, two old guys that aren't really big DIY car guys took 2 days and a few bruises but we installed at all 4 corners. And without having to call anyone for help! The video from etrailer was a key factor there. The tip on removing the wheels for the rear install was probably the biggest piece I got from it and honestly I'm not sure how you can drill those holes without doing it. I highly recommend the Sumos and etrailer was fantastic in getting products shipped and providing good support info to make the install easier. 710787

Roadmaster

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. 713883

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. 680484

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! 666314

Came packaged very well. Instructions was easy to follow. Would have been much easier if I removed the rear wheels when drilling holes for top bracket. But install can be done without removing any tires Great site and easy to search for products that fit my RV. 643661

The product worked better than i anticipated. The front end was dramatically smoother on our coach. The ride was so much better we ordered the rear set today and are anxious to get them to Protech Diesel for install. We test drove a diesel coach and now this ride is gonna be pretty close to airbags. I highly recommend... 555145

Great product, installation was not bad on a 2011 Thor Hurricane 31j, improved stability and dampened bumps and expansion joints also in my opinion has also helped isolate the road noise. 474646

  • SumoSpring Suspension Enhancement for 2017 Fleetwood Bounder with 22k Ford F-53 Chassis
  • If you wanted to install SumoSprings on your 2017 Fleetwood Bounder built on a Ford F-53 that are designed for the higher GVWR chassis you could but you should note that it would probably give you a harsher ride quality than you'd want. For GVWR between 20k and 26k you'd want the part # SSR-187-54-1. The kit for 20-22k like what you have would be the part # SSR-180-54-1 which would give you the support you want without sacrificing ride quality. I can see how it would be tempting to...

  • Best Heavy Duty SumoSprings for a 2016 Fleetwood Bounder 35K
  • The SumoSprings Rebel Custom Helper Springs # SSF-173-40-2 will fit the F-53 chassis on your 2016 Fleetwood Bounder 35K but is rated for motorhomes with a GVWR from 24,000 lbs - 26,000 lbs. Since your 35K has a GVWR of 22,000 lbs I recommend going with the SumoSprings Rebel Custom Helper Springs # SSF-170-40-2 instead which is for motorhomes with a GVWR of 16,000 lbs - 22,000 lbs. We are continually trying to update our fit guide to better serve our customers. The reason that we...

  • 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. Then to assist with keeping your motorhome in line, I recommend the Roadmaster...

  • 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...

  • Comparing Timbren and SumoSprings for a 2018 Ace 30.2 Motorhome
  • Yes, the front # TFFF53B Timbren suspension enhancement are similar to the front # SSF-170-40-2 SumoSprings for your 2018 Thor ACE 30.2 Motorhome. Timbren is a little more well-known but we have received feedback from our customers that the SumoSprings offer better ride quality as they aren't as stiff. If you are comparing the rear Timbren # TFRF53A with the rear SuperSprings # SSA41 for the leaf springs then they are comparable when it comes to performance but they work slightly...

  • Correct SumoSprings for 2017 Mirada on Ford F-53 Chassis
  • You did have the rear SumoSprings correctly figured, # SSR-187-54-1, though because your vehicle has a GVWR of 22,000 lbs the correct SumoSprings for the front axle would be # SSF-170-40-2. The springs you referred to are the same but are for vehicles with a higher GVWR. I've added a link to a video review and install of the stabilizer for you to take a look at.

  • 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 Suspension Enhancement for 2018 Forest River Georgetown 31R5
  • According to my research your 2018 Forest River Georgetown 31R5 is built on a Ford F-53 chassis, which is what the parts you listed will fit. The best way to enhance the ride of your motorhome is to add a rear anti-sway bar as it will most effectively limit the side-to-side movement and create a more balanced driving experience. The correct rear anti-sway bar for you is Roadmaster Rear Anti-Sway Bar # RM-1139-145 though this will only fit if you are certain that your 2018 Forest River's...

  • Best Way to Soften the Ride on a 2018 Fleetwood Bounder 36D
  • The best option you have to improve and soften the ride on your 2018 Fleetwood Bounder 36D would be to use the SumoSprings Maxim Custom Helper Springs part # SSR-187-54-1. These springs install between the frame and leaf spring pack. They will work to absorb shock, minimize sway, and improve the wear life of your existing suspension components. The springs are made in the U.S.A. and come with a 2-year warranty. If you would like to get a better idea of how they work you can take a look...

The biggest improvement you'll make is with a rear sway bar, which for that you'd want the # RM-1139-145. Next biggest improvement will be with a front sway bar # RM-1139-140. SumoSprings will help too and are a solid choice. For that you'd want the # SSF-170-40-2 for the front and part # SSR-187-54-1 for the...

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.

I recommend the following parts: Roadmaster Rear Anti-Sway Bar for Motor Homes # RM-1139-149 along with the Extended U-Bolt Kit # RM-590050-00 if the factory bolts are not long enough to accommodate the factory nut, washer, and a new 1/2 inch plate.

  • 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. Since your FR3 is a 2016 I would be surprised if your suspension was worn...

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.

For the Ford F-53 chassis that your Windsport has we have the Roadmaster Rear Anti-Sway Bar # RM-1139-145 which has a bar with a diameter of 1-1/2". Since this is typically larger than OEM anti-sway bars you will definitely be able to tell a difference. This is designed for a vehicle with a GVWR between 18,000 lbs and 22,000 lbs. To add...

  • 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...

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.

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.
