Features to know about

Stay Level and Confident Under Load: 1,500-lb Rear Suspension Support

When you’re towing a trailer or hauling heavy gear, rear-end sag can throw off your steering, braking, and headlight aim. These SumoSprings Solo helper springs add up to 1,500 lbs of support at 50-percent compression to help level your ride and keep your vehicle stable. They work alongside your factory suspension to reduce squat and bottoming out so your ride stays controlled and comfortable when loaded down.

Smooth Ride on Every Trip: Progressive Load Control

Whether you're carrying a light bed load or towing something heavier, these springs automatically adjust to match the weight. Lighter loads compress the springs easily for a softer feel, while heavier loads compress them by as much as 80 percent for solid support. The progressive spring rate means the ride stays smooth when empty but firm enough to handle real weight when needed.

Stay Steady in Crosswinds and Turns: Independent Spring Action

When a curve or crosswind tries to push you around, each spring works on its own to keep both sides balanced. This independent action helps reduce body roll in sharp turns and keeps the vehicle planted even with an off-center load. You’ll notice better stability through corners and less rocking when hitting uneven ground.

Built Tough for Real-World Conditions: Durable Microcellular Urethane

Made from microcellular urethane, these helper springs handle temperatures from -25 F to 200 F without cracking or deforming. They resist oils, road salts, and UV rays that wear out other materials. The springs compress vertically with minimal side expansion so they won’t rub against nearby parts, and there’s no air system to maintain—just simple, lasting support that holds up through years of hauling and towing.

Quick Upgrade Without the Hassle: Simple No-Drill Installation

These one-piece jounce-style springs replace your factory bump stops using existing mounting points—no drilling or air lines required. Once installed, they’re completely maintenance-free with full memory rebound every time they compress. It’s a clean upgrade that adds reliable support without the upkeep of air systems or complicated adjustments.

Video Transcript for Manufacturer Spotlight - SuperSprings Vehicle and Trailer Suspension

Hey neighbors, Kevin here with etrailer. And today we're gonna be spotlighting one of our vendors, SuperSprings International, with Brian here. And why don't you give us a little bit of a background on SuperSprings and what your guys' vision is So SuperSprings International's been around for over 20 years. They started off with the SuperSpring product, our namesake, which is this guy right here, the steel helper spring. And then in 2002 we came in with the Sumo product, which is the yellow, blue, and black product you see there on the table. Our main goal is to just help our customers journey better.

We want guys to get from where they're going, or from where they started to where they're going as easily as possible, as safe as possible, and as comfortable as possible. And that's our goal. We just want to help everybody get where they're going safely and do their jobs, whether it's commercial, whether it's recreational. And we want it to be safe. Well, it kind of falls along with the lines of our vision here at etrailer.

So we have all these parts in front of us. Why don't we go ahead and get a little bit of a breakdown You know, what's the purpose for each one of these You know, what application would I use each one of these for So we'll start off with the namesake product. This is the SuperSpring. That's this black spring here. The yellow spring here, this represents your standard leaf pack on your vehicle.

So the SuperSpring will go over top and help support, pull up on that leaf pack, give you load leveling capacity and additional load support. That was gonna be for vehicles that are loaded primarily 100% of the time. So commercial vehicles, things like RVs. Or maybe even guys that have a landscape company, and they've got the bed of their truck constantly full of stuff, so. Yeah, bigger trucks, maybe if you have, like, a gas tank in the back or other heavy equipment that doesn't really leave the bed each time.

Correct, yes. All right. And then this is our SumoSpring product. This product is gonna be for vehicles that are not loaded 100% of the time. So let's say, like, lawn companies that have a tank in the bed of the truck, and they go out and they spray pesticides all day. At the end of the day, that tank's empty. So they're riding home, and they don't want to ride on a stiff suspension on the way home. They want that nice smooth ride. So this will provide the load leveling they need when the vehicle's loaded. And when it's unloaded, you'll get the factory ride. Sounds good. What about some of these guys down here I know this is gonna be still in our rear suspension. Yes. So this is what we call a SuperSway-Stop. And this essentially just engages your overload sooner. This is meant to be used in conjunction with an airbag or one of our SumoSprings. And then this is a SumoSpring for a sprinter van. It's just a little different style. But still the same microcellular polyurethane product. Kevin And finally. This guy right here, this is the Coil Sumo. So these just slip into your standard coil spring on your vehicle. They give about 30% capacity back to your vehicle. They will reduce sway, body roll, and they'll mitigate some of the vibration. Yeah, I actually have some of that on my truck myself, and I can't speak enough about, you know, the better handling, just not leaning side to side as I make turns when I'm cornering, especially if you're going at a higher speed. So honestly just super easy. Great product that's pretty much maintenance free. Is there anything we should be doing with these or even our Sumos No. Are they sort of sprayed down at all at any point, or Nope, you don't have to. They are chemical resistant. The microcellular polyurethane is a very durable product. The road salts and stuff won't hurt them. I mean, it doesn't hurt to spray them off and keep them clean, but we've had no issues with them breaking down. They should last over the life of the vehicle. Kevin Sounds good to me. Now, with our SumoSprings, how would I differentiate what's gonna be the best for me You said, you know, these are more for if you're not hauling heavy every single time. How would I know what size, color, capacity is gonna be the right fit Sure. So typically, blue is gonna be for your lighter recreational vehicles, black is gonna be more for work trucks, and yellow is gonna be more oriented towards commercial trucks. Now, depending on the application, the densities will be different according to the size of the Sumo and how much nitrogen we put into them. So each application is slightly different. But as far as the load carrying capacity, we'd have to pull up the specs for your specific vehicle and see which each one lists. 'Cause a blue is not gonna be, let's just say, 1,000 pounds for every vehicle. A blue might be 500 pounds for one vehicle, and it might be 1,000 for another. So we really gotta look at the specs there on the website to really dial that in. Kevin Okay. But these are gonna be more for your, these are gonna be for like 1,500 to 2,500 trucks. When you get into these, we do use these on a lot of RV applications. A lot of 2,500s, 3,500s. But if you've got, like, say, a F-350, 250, 450, you know, 3500 Chevys, that's where this product shines. This is our two-piece Rebel product. So as you're riding down the road, it'll sit about like this. You'll have about an inch, inch and a half gap. So as your suspension moves, you know, you get your factory ride. Now, as soon as you load a trailer on that, it'll come down, it'll touch, and it'll give you 5,000 pounds of load support at that point. These are meant as an airbag replacement. So they'll fit in the same location as an airbag would. And they're a little more heavy duty. So, you know, you're getting 5,000 pounds with this. Whereas these, you might get up to, and I'm just guessing off the top of my head, I think the yellow I think might go up to 2,000. Maybe a little more on certain applications. So, you know, if you're hauling big trailers with a 350 or something, that's gonna be the product you're gonna need. This is typically what we see a lot of down in the shop, just because we have a lot of motor homes come through. As you know, motor home suspensions, pretty much non-existent for comfort. It's just to get you from A to B. Correct. So this actually does make a huge difference on that ride quality. You're not feeling every single bump in the road, and you're actually able to kind of drive around without feeling like you're swaying back and forth so heavily. Correct. Correct. Yeah, that will give you the sway control. It'll stop the vehicle from sagging. It'll mitigate a lot of those big jolts and the jounce thing that you get from a trailer sometimes. You know, 'cause a trailer suspension, there's not much to them. You know, they don't spend a lot of money in the trailer suspensions, unfortunately, and they don't have shocks. So they get to bouncing, and sometimes you'll feel that in the cabin of the truck, and those help mitigate that. So what can we do to kind of quell any neighbor's concerns with any wear and tear on the products Is there anything that you guys see Kind of any kind of returns that you're seeing a lot of, or anything that we should kind of focus on The only real issue that we see returns-wise is usually incorrect installation. As far as the durability of the product, we have torture tested it many times, and they should last the life of the vehicle or longer. We actually have a video on our website that people can pull up, and we do a torture test where we submerge it in a lake for two days, we drill holes in it, we shoot it with a gun, we blow it up with Tannerite. I mean, we drag it behind a truck, we burn it. And then we put it right back on the vehicle and put a trailer on it, and it still performs like it did from the factory. So as far as their concerns, no, there should be no concerns. I mean, the product is is very durable. So I don't know if that helps answer your question, but, you know, in my mind, once you see that video, it put me at ease as far as the product durability. 'Cause I know a lot of people think, "Oh, it's foam." Well, it's a little different chemical makeup than that. It's quite a bit tougher than foam. It will outlast your vehicle, I promise you. We have our zero maintenance policy, which tells you there's nothing you need to do to it. You don't need to hose them off. You don't need to keep them clean. Lifetime warranty. So if it comes off the vehicle, you lose it, we'll replace it. If something happens, it's destroyed, we'll replace it. That's to the original owner only. And then a 30-day money back guarantee. So if you buy it and, whatever reason, you don't like it, in 30 days, return it. So for smaller crossover vehicles, people who are just kind of starting to get into this world of trailer towing or just off-roading, camping, stuff like that, what would you recommend for those people that just don't have the leaf springs to add a SuperSpring to, or there's not a fit when it comes to the Sumos Which product would you want to throw in So in that case, our Coil Sumo is gonna be the product they're gonna want. These slide right into your coil springs. You can use them front or rear. If you're hauling a trailer with a smaller crossover SUV, this will help give them the capacity to do that without the back end sagging really far. You can use them in the front and it'll help with sway control or nose dive on braking. We've actually got some police departments that use these on their Explorers. They we inchesre having issues with stability at high speed, and these mitigated that issue. And how would we go about figuring out which one is gonna fit exactly Just because there's not really a great guide, at least on our side of it. Everything's kind of fit guided for each specific vehicle. So when there's not that fit, you know, how would we figure that out Yes, so with that being a universal product, there are many different sizes. We can go on the website. And there is a tool you can print out and cut out. And you just slide it in between the coils, and whichever one fits in between the coil, it'll have a part number on it, and that'll tell you which one you need. So we've talked a lot about vehicle suspension. Can you tell us a little bit more about your trailer suspension side Sure. So this is gonna be our Trailer Sumo product. This specific one is meant to mount on top of the leaf pack. We have two main styles. You have spring-over or spring-under. That's gonna be two important things to ask. And then the next thing is gonna be what the spacing is above the spring pack, 'cause there is a minimum requirement to fit these in there. Yeah, you get them in between that and the frame. Correct. How would I know what is the right capacity for me I think this is 5,000 and this is 7,000 pounds. So I just need to look at the axle and figure out what my capacity is. Correct, yes. Yeah, we look at your trailer and what axles are under it, and that'll tell you. Okay. And then this just follows the same thing as everything else. Maintenance free, same kind of compression rate. Correct. Maintenance free, lifetime warranty. They will help with vibration. They're gonna help with sway and trailer bounce. They will also help that trailer carry that load and keep your load from shifting as much. That's super important when you're hauling heavy stuff on your trailer. You don't want it shifting it around. Correct. And definitely don't want that sway. So much-needed improvement. It'll reduce the bounce and vibration you feel into your vehicle as well. So with all the new campers out on the market, a lot of them really have never towed a trailer before. They don't really understand, hey, you know, this isn't like just driving my car. It's not gonna feel the same. A lot of people come to us and they're wanting either a cushioned pin box or cushioned fifth wheel, or maybe even, if it's a travel trailer, they're getting a cushioned ball mount, just to kind of take away that road shock and all that vibration. You know, what are these Trailer SumoSprings gonna bring to the table What are these kind of helping with So these guys, they're gonna help reduce vibration. We did some testing with the Grand Design's camper at the Navistar Proving Grounds, and we saw a 68% reduction in G-force vibration and 133% change in vertical displacement. We knew they would work well. We just didn't realize how well it was gonna perform. It was pretty astonishing, the difference between with and without. Night and day difference. And I have no qualms that your customers, your neighbors are gonna feel the same way. These things have very cheap suspension put under them from the factory. So they don't put a lot of engineering into this suspension, unfortunately. Most of the money goes to the inside, where people spend most of their time. So people don't know that the ride and the towing can be better until they experience it. And that's what these will provide. So in summary, each of these products kind of has its own identity in the market for, you know, each different vehicle, each different kind of application. But, you know, it's all gonna get you from point A to point B nice and safe. Absolutely. Yeah, our main goal with all these products is to get you where you're going safely and get you there with the best ride quality we can. Whether that's recreational or commercial, it doesn't matter. We want you to have the best experience and the best journey possible. Well, that's great to hear. Definitely along the lines of our vision here as well. If this video wasn't helpful to you or you still have questions, please feel free to reach out to us either with an extra question, a comment, or a phone call. We'd be happy to help you get set up for your journey.

This only pertains to the order, shipping speed, and install as I have not put a heavy load on these sumo Springs yet but I feel like that's a foregone conclusion based off the reviews already. The ordering process, the shipping, and the installation was unbelievably easy. I kept rereading the instructions thinking this can't be right because it was so simple. I looked at the YouTube video and realized it is that simple! So happy with the ordering process, the quality of the initial product I opened, and how simple it was to put on the jeep.

@ClaireH yes Ms Claire. I plan to put a truck camper on the Jeep (that weighs in the 500-1000 lbs range). My payload is 1700 lbs so I know a camper of the weight will be significant my truck. Already ordered a stiffer rear anti-sway bar as well.

@Justin That sounds like a good plan! These SumoSprings plus the sway bar should be more than enough to handle the weight of your truck bed camper.

I put these on a 2013 Jeep JK (not lifted) that tows a 3000 lb trailer in rough terrain; Total game changer.

These replaced the anemic factory stops (which had completely disintegrated) and make it impossible to 'bottom out' on the dips and holes that use to beat up the suspension. I got nearly all of my vertical travel back and the vehicle now sits almost level under high tongue load.

They go on pretty easy. I suggest sliding in one side, and then using a wooden dowel and hammer to pop the other side in the stock receiver cup.

Highly recommended. These are a MUST if you are towing a trailer (with a medium sized SUV) of any significant weight or if you just want to be able to bounce hard without bottoming out your suspension. I am likely going to get the front suspension version now as well.
Wish I knew these existed sooner.

At that time I jacked the rear end to allow clearance. One side at a time. Took longer for set up then the job. I used the long bolt with two spacers. Have not drove yet, though looking for great results.

Great product! Bought these for my 2000 7.3 f250. Didn't want something that is constantly active like ras or hellwig since my leaf springs are new and rated for 4k pounds. Installed these in 1 hr super simple only hard part was the factory bump stop on driver side was a pain. Didn't install the puck they give due to height of truck and I knew more or less at what point I wanted them engaging. I haul cattle to shows/ auctions or between pastures with my 24ft big bend and these things actually provided a smoother ride in my truck loaded then unloaded.they do a great job with the added support and are better than an overload spring with handling sway and providing a smooth ride loaded. Just wish I could use the 3k pound rated ones on this truck and my dually but doesn't fit if you have a gooseneck sadly so will probably have to go with timbs on the drw. Over all great product can't speak to longevity but solid for the time being. And customer service with this company is excellent if you have a question or problem they're on top of it...hope they pay them as well as the reputation they're building for them.

I put a set of 47s on my Silverado 1500 and towed my dump trailer that weighed 6000 pounds the way I had it loaded for 50 miles on all kinds of roads and it worked well. I didn’t use the spacers and the truck still rides like it did before the install.

Glad the Sumos are helping make your loads easier to tow!

by:
Jeep Gladiator Mojave - swapped out the rear stock bump stops with these. High quality parts. Just jack up the truck enough to give you room to work with and put in your jack stands, no need to remove the wheels. I look forward to seeing how they do with towing! Hopefully I can update my review here afterwards. Check out the gap difference in the pictures. Should touch sooner during normal drive conditions and hopefully help reduce some trailer squat and help towing to be smoother.

Opted for the Blue 1000lb Sumo's w/spacer over the 1500lb Black ones. 1500 Silverado Max Tow & reduces squatting by 2" on a 1000lb+ tongue weight. Ride is still good, but you can feel the Sumo's engage over large dips or bumps which is not an issue for me.

I got the springs installed last week and wanted to have a drive time before I wrote the review.

The height of the springs are perfect for my 2016 Tacoma, They keep the truck stable and nearly eliminate the body roll I had before installing them. I am heading to the mountains in a couple weeks, so I will update the review when I get back. That way I will know for sure the body roll is gone and the truck is stable on the winding mountain roads.

The springs installed in no time at all and since I had the rear end apart, I decided to add the leveling blocks at the same time, to keep the truck from squatting with the gear I haul around with me.

The guys at etrailer are great. And while I did not call them to discuss this item, they have been very helpful in the past with all my questions.

Below are pictures of before, a couple comparisons and after. Sorry if they come out sideways.

These Sumo Springs were a great addition to my Tacoma and well worth the money, IMHO.

The springs are working exactly as expect. I have need up to the mountains numerous times and to Monerary to the Sea Otter bike fest. They have reduced the body roll and helped keep the truck stable on the mountain roads or when loaded down for camping. Im very pleased I added these Sumo Springs to my Tacoma.

Got them installed no issues the reason for 4 stars is one side touches top of axle the other side does not no one could tell me if this was right or wrong also haven't pulled 5th wheel yet to feel the ride or handling so we will see thanks

Definitely helps with squat on '24 F250 from boat trailer tongue weight. These do come with a plate to avoid uneven contact or wear.
I mounted using all spacers , stock is same unless speed bumps or large dips, u feel the stiffness/contact of sumo as expected. May take one spacer out .
Super easy to install , better than leaking bags.
Time will tell how they last

Glad to hear they are helping, Cory! If you are feeling them going over speed bumps, I think taking one of the spacers out is a good idea. Especially if that is happening when you are unloaded. Speaking of which, what are you towing?

I had installed this model SumoSpring on my 2019 4Runner and had great results when towing the camper I had at the time. They greatly reduce the bounce when going over dips in the road at highway speeds. Now I have a 2021 Titan and a bigger heavier camper. I expect the same great results on the Titan. Installation was pretty straight forward and took about a half hour. The size difference between the OEM bump stops and the SumoSprings alone should give a better ride when towing my camper.

I bought a 2027 RAM 1500 to tow my 20' 5000lb Forest River. Easy to install. I did it in my driveway in 1.5hrs. Some of the bolts were dificult to access due to mufflers etc but a short wrench worked well. When I first hooked up my trailer I had 4" of rear bed setelment. With springs installed I had less than 2". Front lift is about 1/2". Did not compromise driving comfort and appeared to dampen trailer "flex" on RxR tracks etc. My right handled very well on a trip from S Florida to N Georgia on Interstates and secondary roads.

Had them installed and hooked up the trailer. Much improved support from sag due to tongue weight. Kept the vehicle very level to within 3/4" higher than front. Perfect rake and comfortable during unloaded or loaded driving. OEM bump stops really didn't do anything in comparison. Shop had to work a bit harder to get OEM stops off but install of these SomoSprinhs was simple. Glad I went this route.

I had the SumoSprings Solo Custom Helper Springs installed on my 2020 Nissan NV2500 camper van (rear axil) about 4 months ago and have been very happy with how they have performed.
by:
Installed these right before a long road trip, and were impressed with how much the ride improved. Opted not to include the spacers, which has worked out fine. While not towing have not noticed any change to the ride, which is good. When towing the steering has a solid grip on the road now (sometimes felt a little loose before installing these) and no more issues with 'porpoising'. We drove across a several mile long bridge in the Bay Area that likely would have been a roller coaster ride previously, and had no issues. Quick and easy to install.

One of my favorite things to recommend Kevin, the feedback is always so great on what a difference they make! What are you mainly towing that needed the extra support?

by:
I bought and installed the 1000lb Sumo Solo springs to help alleviate rear end squat on my 2024 GMC Canyon Denali when pulling my boat. My boat trailer has a long mono tongue with no weight distribution installed. The boat weighs in at about 5500lbs, the truck fender lip measures 38” high unloaded, once I dropped the hitch down on the ball and the Sumos picked up the load, the fenders measured 36.25” equating to an inch and 3/4 squat. Empty the Sumos have an apx gap of 7/8” above the frame rails. The Sumos were recommended over the Timbrens for my situation of infrequent towing with this truck and to maintain the best ride possible when not towing. So far my ride is virtually unchanged when empty and feels controlled when towing. Installation is straight forward but the instructions could be a little clearer with a diagram showing the intended location of the springs. Luckily an etrailer customer had already done the install and provided some pics so there was no question. I chose to remove the tires to have good access and I’d do it again this way. I supported the truck with a jack stand under the receiver. IMHO the proper method to locate the over frame upper clamp brackets is to push the forward clamp as far forward until it contacts the bed stiffener and you’ll be in the correct location then let all the hardware hang to position itself, tighten as required and enjoy.

Excellent, I also tow a 6x12 cargo trailer which the Sumos do a great job of maintaining a level ride. I also installed Sumos front and rear on my 32 Tiffin motorhome. It utilizes the Ford F53 chassis and I believe they compliment that chassis well. Im definitely a big Sumo fan.

I was surprised at how much of a difference these actually make. I bought them based on some videos of others using them, but wasn't sure if they would actually make much difference in my situation. I tow a 6800lb trailer with a Silverado 1500. With the tongue weight of that trailer, the rear of the truck doesn't drop all that much and I wasn't sure if replacing the bump stops was even necessary, but when I'm on roads with "heaves" and especially bridges where porpoising can be a problem, these SumoSpring certainly help. You probably won't notice some huge drastic change, but it's just enough to matter and even out the ride to a noticeable degree. Also, they're pretty easy to install (and I'm only barely handy when it comes to this stuff.)

I'm glad that the Sumos helped with the handling, David! And I think your pretty handy if you can get these installed :)

I've never put on a easier product. I put the jack under the trailer hitch mount. Just lifted the body 1-2 inches and used a 12 mm socket . The socket removed the old ones and I hand tightened the new on. Literally took 10 minutes and a beer.

That's the beauty of SumoSprings, easy to install and once they're on you can forget about them and let them do their job!

by:
Easy installation , fit perfect . Can’t wait to see how they work towing my travel trailer .
by:
I bought these but still have not managed to install them (trying to give full force while underneath the car on jack stands unnerves me). But I do believe these will be a great upgrade given how well the front bumpstocks worked out.
