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.

Drove our 38' class A gas coach for 6 months prior to installing Sump Springs. World of difference. Pulling from a parking lot to flat road used to involve 3 or 4 rock's left to right. That is gone. The porposing on the freeway is much better also. Overall feels more stable. Still shutters and has a truck like ride on rough roads and bridge abutments. 640809

Excellent product. I have a 2018 Thor motor home on the Ford chassis. After purchasing it and driving it 100 miles home in sustained 40 mile mph winds, I was starting to regret buying it. Even without wind, it was a handful to drive. I purchased the sumo spring for the front and rear. The change it the handling was way better then I expected. Even in high winds. Nothing will stop all the effects of the wind on a motor home, but I can now drive it 70 mph with confidence. The biggest change was with the side to side rocking. Driving on uneven lanes and on two lane roads with out shoulders is no longer a problem. I installed them myself without removing the tires. You have to use a right angle drill. It took me 5 hours to do it, but I’m 60 years old and slow. I plan on doing other improvements like steering stabilizer and track bar. Adding the sumo spring is the best thing anyone can do to improve handling. I actually enjoy driving my motor home now. 634453

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. 661100

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


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

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

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


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

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


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

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


Installation was quick and easy. the instructional videos were the deciding factor to purchase this product. after installation everything was just as claimed. adding a 2300 load in the bed of the truck cause very little squat and actually lowered the front about an equal amount (1" in the back and 1/4" in front). since 60-70% of the trucks braking is from the front wheels this was import to me. options were airbags, adding additional leaf springs or this option. I was cautioned that when your vehicle is service with airbags installed putting the truck on a lift for oil change for example you might tear the airbag. this option on a lift the two sections just separate and go back together when lowered. I was happily surprised by the side to side stabilization removing the need for additional suspension additions. ask me again after a year 656968

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

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


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

Review from a similar SuperSprings SumoSprings Rebel in Vehicle Suspension


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

    The SumoSprings Rebel Custom Helper Springs - 2 Piece - Front Axle # SSF-173-40-2 will support the load and compress together on your motorhome all the time when there is weight. The split design is a benefit for the individual springs when the suspension travel is greater than what a single non-split design could handle.
