SumoSprings work to improve your vehicle's front suspension. 2" lift spacers are included to accommodate your lifted Jeep. These springs will bear the brunt of the weight for your heavier loads while you are traveling off-road, whether for work or for play, and they will help to absorb the bumps and shocks that can happen on rough roads. The springs work with Jeeps with winches, aftermarket bumpers, and other heavy front-end equipment. They were designed for off-road use.
Safer Off-Roading
Frequent carry of heavy cargo can cause front-end sagging as your OEM suspension system compresses to accommodate it. Your vehicle can also sway if frequently under heavy loads, as well as bottom out, which wears your suspension down. If the weight isn't even, then it jeopardizes your ability to steer and brake. These springs reduce these problems by compressing accordingly with the weight of your cargo and helping support and distribute the weight. SumoSprings make driving heavier loads more comfortable for the long haul, and they give the control back to drivers when sway is minimized. The progressive load control works differently, depending on whether you are carrying a lighter load or a heavier load. If you are carrying a lighter load, then the springs will initially compress easily and smoothly. This will create a soft engagement for the springs and a much less bumpy ride for you. If you are carrying an extreme or heavy load, then the springs will help to support your vehicle's suspension by compressing up to 80 percent.
Faster Activation
These off-road helper springs have a taller rubber jounce than standard helper springs and are effective off-road when other springs are not. They engage more quickly, so you can travel over rocky or rough terrain safely and comfortably.
Durability
Made in the USA, these springs are constructed from durable microcellular urethane material, which withstand the elements. SumoSprings resist any damage caused by oils, road salts, and UV rays, so you don't have to worry about them failing to do their job while you are traveling on rough road conditions. They work in a variety of temperatures, from -25 F to as high as 200 F
No-Drill Installation
The kit is designed to install easily above your existing front axle factory springs. No drilling is necessary. The springs have the ability to operate in tight, closed-in spaces. They can expand and compress vertically without taking up any room on the sides. Unlike air springs or air bags, you don't need to maintain SumoSprings. The springs will never leak, and you don't need to run the tubing or monitor the air pressure.

Video Transcript for SuperSprings SumoSprings Solo Front Axle Helper Springs Installation - 2023 Jeep Gladiator
Hi, Matt with etrailer. Today we're gonna be talking about our SumoSprings solo helper springs on our front axle on our 2023 Jeep Gladiator. Now this is gonna be a great suspension enhancement as opposed to what comes standard on your Jeep. Now this is gonna give you more stability and we're gonna be great for going off-roading or if you have a heavy load on the front of your Jeep. And as for the material, on top, we're gonna have this steel with a black powder coat finish to it. So it's gonna be resistant to rusting.
And for the spring itself, it's gonna be made from a microcellular urethane. And what that's gonna do is help it be more resistant to anything on the road like salts, oils or anything else like that. Now you can get this as two different kits. One is just the standard or one with a two inch spacer. That's just gonna be put on top of here.
And that's just gonna be for if you have a lift kit installed on your vehicle and you need that extra spacer, it's not sitting up too high and not making contact at all. And with the Jeep being very customizable, whether you're adding winches or new bumpers to the front of it, this is gonna be able to stand up to that with a weight capacity of up to 1,400 pounds. Now you're probably never gonna reach that amount, that's just what this is rated for so you know it's gonna be able to stand up to whatever you throw at it. And now that we've taken a look at the features, I'm gonna show you how to install it. Now, to start off the install, first we're gonna get our vehicle prepped up.
And so what we're gonna do is we're gonna chock our back tires. Then after that we're gonna wanna make sure it's in park and have your parking brake on. And then we're gonna jack it up and put two jack stands on either side, making sure the front is lifted up so we can access it. And then I'd recommend grabbing some penetrating oil and just spraying those bolts that you're gonna be messing with. First things first is when we're taking our tires off, make sure you break these loose before you lift it up.
And after when you've lifted it up, we can just grab our impact tool and take our bolts off. Now we're just gonna lift up, pull it towards us and set this aside. So we're gonna have two 10 millimeter bolts we're gonna have to take off. So this is gonna be the first one, and the second one is gonna be up here. And it's gonna be right next to this other piece here that we're gonna use a trim tool to remove. So we're just gonna come over here and just unbolt this, and once you have this all the way off, you're gonna have this tab that's in here that's gonna be removed too. And I'll show you how to do that in a second. And then just pivot this out and slide it forward. You might have to wiggle it just a little bit, just like that. Now we can move to up top and move this bolt too. And with that removed we can now grab our trim tool and pop this loose, just lifting on the back, getting underneath it, sliding this through and applying pressure. Just like that. And with this loose, we're gonna remove this next bolt, which is gonna be a 15 millimeter. I'm just gonna come over here, loosen this up. Next up is gonna be loosening up this sway bar and we're just gonna remove these two bolts on this bracket that's going to drop this. And we're gonna do that on both sides. You can make this a little bit easier by removing the skid, but we still have access to that since we're using that extender. And we're just gonna come under here, line everything up, line your pressure and take it off. And now with both bolts removed, we can have this dropped out a bit. Now before we proceed to the next step, we're just gonna grab our floor jack and jack this up until it's making contact with this bracket on the bottom 'cause this is gonna be the last thing holding up our axle once we remove our bolt from our shock. Now we're just gonna take this 18 millimeter wrench, put it on the backside so it holds everything in place and grabbing our socket wrench. And we're gonna loosen this up now. And then you'll get to the point where you can just remove this bolt with your hand. And now we can work on driving this bolt out and we just wanna make sure that this shock is out of the the way and none of these brake lines are gonna get caught on everything. And when everything looks good, we can start our jack very carefully because we want that spring to extend. You go a little bit at a time going back and forth 'cause we just want this a little bit to where the spring's gonna unseat either at the top or bottom. Might have to wiggle it some to help you. Once you get to this point, you can just pull it right through. And with our jounce bumper accessible now, we're gonna just get some soapy water, spray it a little bit, so it's gonna be a little bit easier to remove. And then I'm gonna grab our trim tool and help me get it off just kind of sticking it underneath and pulling on it some. Just like that. And now when we're looking at either one, you'll probably notice we do have quite a bit of a size difference. This is how they're gonna compare. And you can kind of see this wider portion that's gonna be where it's not exposed. And this darker portion is kind of be what's gonna be exposed. And as you can see here, there's quite a bit of a difference. So this one's gonna make contact before our jounce bumper is. And what's nice about that is you're gonna get more of that resistance first, but it's not gonna be a harsh resistance. But that first 20% of it, it's gonna be a nice easy give. So you don't have to be gripping the steering wheel when you're going over those hard bumps. Now after that, you're gonna start getting that progressive load control, giving you more stability on your car. So now we can take a closer look at our hardware itself. So besides the SumoSpring itself, we're gonna have these 16 millimeter bolts and washer with it. And along with that you're gonna have some blue Loctite. Now we're doing this for demonstration purposes today, so we won't be using the blue Loctite. By the way, you would just apply it just on some of these threads. And the way this is just gonna install is the SumoSpring going underneath and us putting that bolt through the top. So getting in that in here is a little bit tough, especially with this fender right here. So what we're gonna do is use this three inch extender and this 16 millimeter socket. And how we're gonna do that is just by lifting this back, grabbing a bolt and our socket, making sure everything's pretty close together placing them in there. And I'm gonna use my finger underneath to kind of guide this bolt where it needs to sit. Now since we have our socket wrench attached to our bolt, we can grab our SumoSpring and thread it onto that bolt that's coming through and tighten everything up. We wanna make sure we apply pressure to our socket wrench so this can thread on. And from this point on we can put everything back together doing it in the reverse order as we took it off. Now something that helped us get the spring back in place is we started, it would just the spring on our SumoSpring and then we actually threaded the spring into place until we we're able to get it lifted up and placed back on here. And now what we're gonna do is just raise this back up, make sure we connect our shock back into place and our our brake line into place. Now I don't recommend putting your sway bar back into place because you wanna leave this down so you can repeat that process on the other side. And that was just a look at our SumoSprings on our 2023 Jeep Gladiator.

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.
by: Tony04/08/2023
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
by: Jeremy01/04/2023
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.

I originally purchased the yellow sumo for additional support when hauling a small trailer or taking trash to the dump so I wouldn’t strain the vehicles suspension that I just replaced . I also never like to see a truck squat . Yellows were too stiff when unloaded so I got these blues sumo and it was a great decision . The ride type is back to original “comfortable” and the sumo still provides great handling when cornering reducing body sway / shock absorbing bumps. A good investment !
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: 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: 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: Tom 05/12/2024
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.
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: Deborah04/19/2024
These Sumo springs were a great upgrade. So easy to install, less than 20 minutes.
by: Gerry 05/17/2024
These have helped keep my 2014 Tacoma level when towing my RV and trailer. Fairly easy to install, reduces sway and minimal trailer squat with heavy loads. Some stiffness unloaded in colder weather but would recommend and install on my next vehicle.
by: Roadtrek Installer01/04/2022
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.

We pull an off-road teardrop camper with our 2013 Toyota Tacoma and were looking for a little help with the rear end sag when we have that hitched plus putting some weight in the back of the truck (firewood, water, etc). Our Tacoma is lifted (2.5") but the lift kept the stock springs with an added Deaver leaf to help with the notoriously soft Toyota springs. However, with the shell and ~300 pounds of weight in the back, it still sagged, especially with another 250 lbs of tongue weight from the trailer. The Sumos have eliminated that sag, even with bigger loads in the bed, eliminated body roll (also notoriously bad with Tacomas) and didn't destroy the ride for day to day driving. There might be a slight bit more stiffness when hitting speed bumps, but definitely not bad at all. If anything, I would say it IMPROVED the ride and handling.
The springs themselves were simple to install, less than half an hour start to finish. Some reviews have said they were bumping the frame after installing but we had about 1/2" gap on both sides. The only "specialty" tool would be a torque wrench capable of 90 lbs to get it to spec.
We considered Firestone air bags but after talking with the reps at e-trailer, we decided on these and couldn't be happier. Reasonably priced (half the price of air bags), no maintenance, great customer service...can't argue with anything at all.
by: Stan10/30/2023
These springs are amazing! They helped tremendously pulling my landscape trailer with all my mowers. I picked up a tractor impliment that I would normally bring a trailer for, but decided to put these springs to the test. Couldn't believe how good my truck rode and handled with 780lbs at the rear of my bed! These springs have exceeded all expectations.
I will say that I initially put the spacer, but found it effected my ride to much so I pulled it. Afterwards it rides like stock.

2015 Frontier Crew cab Desert Runner (purchased the yellow Sumo Springs). Easiest install ever! 18mm deep socket and long breaker bar for breaking nuts loose. Removed factory bumpstop, install sumo bracket and retighten U bolts to 58 foot pounds. After installing both brackets, lifted back of truck up 4 inches to install sumo spring with blue lock tight on bracket bolt, tighten sumo spring onto bracket and lowered truck off the jack. Overall it raised the back of my truck bed 1 inch. Ride is stiffer with no bed roll in the turns. Loaded my 24 foot travel trailer with load leveler- equalizer bars and gained 3 inches (less “squat”.) Truck is level now vs nose high (without the sumo springs). Definitely an upgrade that was needed in 2015 when I first bought the truck!!!
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.
by: Richard06/02/2021
Very straight forward installation. Simple. very noticeable difference under load. Towing with the gooseneck also an improvement, looking forward to the longer road trip test. So far pleased with the product and results
