Rear Suspension Support
Towing or hauling a heavy load can cause rear 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 weight of your vehicle. 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 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 closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
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.
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 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.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

Video Transcript for SumoSprings Solo Rear Helper Springs Review SS28UV
Hi, everyone, Aiden here with etrailer. Today we're gonna be taking a look at the SumoSprings solo line of custom helper springs. This is gonna come in a variety of different fits, and have different styles of spring. So let's check them out and talk about the differences. Now right away, this is going to be for the rear axle. You can see we've got one installed on our 4Runner today.
That's just one of many fits available, and it's a direct bolt on installation. Now with the rear axle, it's gonna help with a number of things. In any sort of towing applications where we've got a lot of tongue weight on the hitch, bringing the back end down, and the front end of the vehicle up, it's going to help return us to a more normal ride height. Now, unlike an airbag that's adjustable where you can tailor it to each load independently, this is going to be pretty much fixed, but it will provide a lot more support, especially compared to the factory bump stops. Now, this is just an example, because every vehicle fit's gonna be a little bit different, but just the overall height difference between the factory and the SumoSprings option is going to be pretty drastic.
So with these being so much larger, they're going to make contact with the axle a lot quicker, so we get quicker engagement and support. So we don't have all of this open air between the bump stop and the axle, where if we hit a bump with a heavy load, we feel all of this bouncing, or side to side, we don't feel as much sway, because this may contact a lot quicker, and provides that support when we need it. And with the SumoSprings, there are gonna be multiple different kinds. If you're looking at different options, you'll see a blue, a yellow, and a black one, and they are different. They really differ in the density.
Overall function and fit, it's gonna be pretty much the same. For example, on the 4Runner here, one of these black ones is available, but also a blue one. It's gonna be the same fit, but they offer different support. The blue one is going to be the lightest density, the black one is the medium density, and the yellow is the most extreme heavy density. That just means as you get more dense, it provides more support, and all of the weight capacities, depending on the kits, will vary a little bit, but as a general rule of thumb, you can go by that color scheme to find out whether you need the light, medium, or heavy duty option.
Now these feature a progressive spring rate, and what that means is the more they compress, the more they're going to push back and support, and try to bring the vehicle back to its normal driving position. So the initial first bit of compression is going to be a bit softer and easier to move. So for normal day-to-day driving when you have these installed, it isn't going to be as stiff. Then as we get into heavy loads and we start getting pretty extreme compression, it's going to work harder to push back to that normal state, and bring us back to a comfortable driving position. Now as far as the construction goes, it's going to be a microcellular urethane material, as opposed to something like a rubber material. Now the urethane's gonna be very heavy duty. It's gonna work in temperatures from negative 25 degrees Fahrenheit, all the way up to 200 degrees Fahrenheit. So you can expect it to work in all sorts of weather conditions. And this material is going to resist all kinds of oil, road salt, and UV rays. So if it does make contact with the sun, it's not going to weather away, and any sort of road conditions, like road salt in the winter, isn't going to cause this to degrade over time. So whether you're looking for support side to side and limiting body roll in your vehicle, or you're looking for backend support for towing, or maybe just something heavy in the hitch like a cargo carrier, this is going to be a great way to do that. It's a maintenance-free solution, so you don't have to worry about maintaining air pressure in it like an airbag, although you don't get as much adjustability with it. I do think that trade-off is very much worth it, because once it's installed, you don't have to worry about it. The installation process is obviously going to vary depending on what kit you get, so do be sure to use our vehicle fit guide on our website to find the right kit for you and your vehicle. But that'll do it for our Look at This medium density SumoSprings solo line of air helper springs here at etrailer. Thanks for watching.

We outfitted our 2 door jk jeep with all the things needed for multi week over landing trips. One problem that’s a lot of weight. These helped with the drivability and stability even on the roads in Baja! The jeep has a 2.5” aev lift and 33” tires. We also left on the 2” spacers on the axle for more preload when weighted down.

I just installed these today. SUPER easy. Didn't even take me 15 minutes. I haven't taken the Jeep out for a test drive yet, but I expect the SumoSprings to perform as expected.

Use these as high speed bump stops and much cheaper than air bumps. Work great!
by: Pete 06/12/2020
This is exactly what I needed! Easy to install and works as it should. Don’t even know it’s there until I pull my RPod.
Nothing to wear out or break! I would definitely order these again!

I believe it’s going to be a great addition to my truck when pulling our RV. Looking forward to a smoother, more even ride. I left the 2x4 blocks in overnig8ht and drove around to ensure a good seat for the springs.

I installed Sumo Springs on our 06 Xterra right after we bought our Casita 17' trailer. The back of the X squatted a bit more than I liked. I had also noticed before some tendency to bottom out if the car was full of people and stuff. These ingenious devices are a perfect solution for me! They are about 3/4" clear of being engaged with the axle when unloaded, so the ride is not overly affected, but progressively take up some of the weight when the back end starts coming down with load. It now sits very nicely with the trailer connected, no weight distributing hitch and stuff in the back, and no more bottoming. We've put a good number of miles on the X in the last year, towing and not towing, and they are still doing the job.
I should note, the back of my Xterra is lifted about an inch with AAL springs. If that were not the case, the Sumo Springs would be engaged all the time. That will vary with vehicle.
I will also note that they are non-adjustable, unlike airbags. I kinda like that, I didn't want to mess with adjusting air pressure and such. But once they do start kicking in as one or both wheels travel, they do stiffen it up quite a bit. I mean, there's no way around that; you can't take load without stiffening the suspension. As such I think they inhibit upward axle articulation a bit when 4-wheeling, but for us that's not a big deal. Since they do not connect to the axle, they don't affect downward articulation at all.
The pics are shortly after installation, one with the car unloaded, and two with trailer and gear loaded up.

Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
by: Dan08/01/2023
These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.
by: Kenneth02/22/2023
Gave it 5 because of ease of install - note they use SAE threads 9/16, truck frame and oem is metric 15mm wrench. Makes no difference but don't use oem nuts on spring. I installed all shims supplied and this left about 3/4" gap so hoing its the best for my needs. Easy to reduce if needed.
by: Thomas07/09/2022
The SumoSprings Solo came to the RV Resort today. I installed them on my Titan SV today in less than an hour. Only drove 10 miles with them and they are what I was looking for. In my opinion it was a needed upgrade and thumbs up!
by: Zach01/24/2024
While these worked great for the first few months and helped level the load, they have now become deformed and squished out of shape permanently. We have a slide in camper that is on the truck for only for trips otherwise the truck is unloaded and off the bumps. I did not expect them to deform so much, and so easily after only a year of use.
by: William01/13/2024
I have had these on my Jeep Gladiator for over a year now and I still like them. Sumo Springs really help with sag when towing my Scamp camper trailer and when the truck bed is loaded with stuff. When it is cold outside they are stiffer and I can feel when they hit the stops on hard bumps. Sumo Springs are a very easy overload spring option with factory lift.
by: Curt03/16/2024
Fairly simple to put on but need to work around the brake lines and bed cross beams. I haven’t tried it yet with weight. I have enclose pic of drivers side. Maybe can’t tell from the pic but there is space and flexibility around the lines around bolt.
by: Darryl 03/06/2023
Straight forward, simple, replacement for OEM springs. These springs make contact with the lower arms all the time and definitely help dampen the bounce effect from a heavier steel bumper. Any rolling effect from uneven roadways and turning is also reduced, it feels the vehicle is more stable. For my situation, this is the first step to take before considering replacing shocks, etc., and is very economical. I'll give it more time, but I believe this is all I'll need to do. Thanks etrailer! Quick shipping!
by: Kevin 04/29/2024
They worked pretty good. They kept my vehicle from bottoming out when towing my 5th wheel camper. They also helped to avoid bucking and chucking upon acceleration. In addition to these though I also purchased RAC rear suspension enhancement springs but having towed with them yet. Hoping for some improvement in general handling.
by: Robert04/04/2024
Hello, i installed the Sumo springs on my 2020 M/B 2500 pleasure Way camper van 19.5 foot, if you do not want to go in for the full suspension upgrades for 5 to 6 thousand dollars the Sumo spring is a
decent up grade to help with sway, we aren’t off roaders campers
but they work nice in unimproved campsite. I have about 4500 miles on my camper since I installed them which took about a hour. It did raise the camper by about 1/4”.
I just used a floor jack and big flat screw driver for the back and deep well socket for the front ones. Sorry I didn’t take a video or picture. But so far I would recommend the sumo springs it is better then stock bump blocks.
And thanks to etrailer for getting me the right setup
for my camper.
by: Louis 04/17/2023
Great upgrade from the oem jounce. Easy to install with 2 people but follow the install video and use a 1/2" deep socket with a long extension. Took about 30 minutes.
by: Preston08/22/2022
Very impressed. Stopped the Tacoma lean. Also helped with the trailer. I do use a distribution hitch I bought from etrailer. Just bought the sumo spring for other applications. Those little bitty factory bumps where junk. These help with lean, and off road hard bounce.They are great.
by: Kris03/16/2023
So glad I found these! Best upgrade for my Winnebago Era Touring Van. Simple to install. I only needed a floor jack to get it done. Van doesnt ride like a boat in a storm anymore. Highly recommend for Sprinter vans.
by: Robert10/13/2023
These do not fit a 2006 ram 2500. As you can see in the
Photo the bolt holes are WAY off. It also does not sit over the axle tube. My only option at this point to use them is to make a 2nd bracket to bolt the helper too. Very disappointed.

- Suspension Enhancement for Front and Rear Suspension of 2016 Jeep Wrangler We have front suspension enhancement that does fit your 2016 Jeep Wrangler and is intended for off-road applications like I can see in your picture, but we don't have any air bag style kits. Instead we have jounce bumper style kits like the SuperSprings kit part # SSF-402-54 which will fit and work well. The tall microcellular urethane springs absorb big bumps and shocks and engage sooner than standard springs. For a matching set for the rear axle we have the part # SSR-405-47 as well.
