Features:
Specs:
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.
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.

Hi, Matt with etrailer. Today we're gonna be talking about our SumoSprings on our rear suspension on our 2023 Jeep Gladiator. So our SumoSprings are gonna be great because compared to our stock ones, it's gonna be almost twice as long. So it's gonna make contact with their axle a lot sooner than what's gonna come stock. And that's gonna be great for if you're hauling anything, you have anything in the back. Maybe not a lot, but a decent amount.
It's gonna make contact first. And for that first 20%, it's gonna be a very nice cushion, very light duty. But then after that, it's really gonna put a lot more pressure and be a lot more sturdier. And now with them installed, we can take it out on the road, see how it feels. We're really watching for how it's gonna compress down and make contact versus just the standard ones.
And we're trying to see how the turns feel, seeing if there's any reduced body roll. So when we compared these, we did our SumoSprings on one side and our stock one on the other side just to see how they held up to one another. And the SumoSprings really helped out a lot. As you can see on the bump course, or the speed bump course, our stock ones aren't even making contact as compared to our SumoSprings, which is staying within the 20% range, which is just great because it's not too jostling, it's just giving us a little bit more assistance as compared if you had another suspension enhancement on back there. If it was getting in that 20% range, it would still be pretty jostling.
But then when we move over to the serpentine area, you can really see where it's helping prevent any of that body roll compared to what comes stock, finding it helping at all. And then when we go off-roading just a little bit, you can see maybe one or two times where the stock one is making contact, but it's not helping a whole lot. Now our SumoSpring's really putting in that work. It's going a little bit past that 20% range now and really giving us that assistance that we need. Now with both of our SumoSprings, they're gonna have some pros and cons.
With the blue one, it's gonna be great for maybe your everyday use, light duty off-roading, something that's gonna be comfortable to drive on 'cause you're gonna have that first 20% when you do make contact, it's gonna be nice and soft, very cushiony. Then after that, it's gonna apply more resistance. And now if you're using the black one, it's gonna have a higher weight capacity. This one's going to be 1,800 pounds as opposed to your 1,400 pounds with the blue one. And this one, after when it reaches at 20%, then after that, it's gonna apply more resistance, and it's gonna give you more of a sturdy drive. Now it's not gonna be as comfortable, but if you have this constantly loaded up in the back, you're gonna want that extra support. Now when we're taking a closer look at the design of it too, what's really nice is this ribbed design. And what I like about that is when it compresses, it's not gonna expand horizontally, it's gonna stay very vertical so you don't have to worry about it expanding and making contact with your springs on the side. And with that microcellular urethane, if it makes contact with any of those oils, salts, or even UV rays, it's gonna be able to stand up to the test of time. Now as far as the installation goes, it's very straightforward, pretty easy as compared to some other suspension enhancements. All you have to do is line up this top ridge up here and just stick it up into this cup. Now between the two, the black one might be a little bit more difficult to install just because it doesn't have that rounded edge at the top, and it is a little bit thicker. But if you need a hand with it, just stay tuned, and we'll show you how to do it. Now to start off the install, we're gonna jack up our Jeep, and put our jack stands on either side. And now I'm just gonna take off the tire so we can get a better look at it. You don't have to if you're installing it on your own, but let's just get a better look at it. And like I said before, we just took the top back tire off, give you a better view of this. Now we're just gonna spray some soapy water, and this is just gonna help us loosen everything up. Now we're just gonna take a trim tool and pry it out from this cup. Just like that. And we're gonna be installing our light blue colored ones, and that's gonna be able to withstand 1,400 pounds. Now if you need something for heavy duty or loads, then I'd recommend installing the black ones, which are gonna be able to handle up to 1,800 pounds. But the installation process is gonna be pretty much the same, and we'll just slide it up until those tabs line up and catch on that jounce cup. And after when you're done with this, just repeat that same process on the other side. And if you took your wheels off, make sure to just put them back on. Then just lower your Jeep back down to the ground, and test out your new springs.

1,400-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.Easy to install works very with aload keeps truck level.
Amazing! I love these things! They keep my truck from squatting loaded.
These spring helpers perform as they should. Install without lifting vehicle.
looks like good quality and easy install , haven't towed with it yet , seems like it should work well .
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.
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper 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.
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.
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.
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!
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.
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.
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.
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.
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!
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.
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.
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.
The Supersprings smoothed out the camper trailer ride especially noticeable on bumpy roads. A good product that does what it’s supposed to do. If I ever get another camper I’ll get Supersprings again.
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.
First off, these won't fix worn out suspension components, they are designed to improve ride quality by reducing sag/porpoising, especially on heavier vehicles.
Our 2010 Roadtrek 210P (75k miles) is a great rv but essentially a big heavy tub going down the road. Has the tendency to lean and wallow front to back. New shocks and all suspension is good, as mentioned make sure that stuff is all in good shape.
Pics show the oem stops vs the SS stops. Big difference - you may assume ride gets harsh but not the case. The oem stops were very tired and didn't do much. The preload on the new SS stops is just about perfect - any weight changes are very progressive which takes the harshness out of the ride. I didn't really see any change to ride height either.
Road manners are improved, there's a bit more resistance to lean, but the main difference is that the front end doesn't try to change height as readily with the back end.
Not a big deal to install. Youbdont need to pull the wheels, just turn them side to side to get to the stops. Pop out the old stops and clean the retaining cups with a wire brush and some brake clean. I used syl-glyde on the new stops to help get them into place. I also used a crowbar under the stop to push it into the cup while making sure the 4 tabs captured the top of the stop. Final step was to lower the van and give it a drive, then check to ensure the fit was good. The key here is to clean the cup first and use a bit of lube on the new stop.
Very pleased and I'll be installing SS on the back end soon. Yup, they're pricey but they are good quality with a limited lifetime warranty.
