Features to know about
Stay Level and in Control: 1,800-lb Rear Suspension Support
Heavy loads can cause your rear suspension to sag, making steering and braking feel uncertain. These SumoSprings Solo Custom Helper Springs add 1,800 lbs of support at 50-percent compression to keep your ride level and steady. The microcellular urethane springs help your factory suspension handle the weight so your tires stay planted and your headlights stay properly aimed when towing or hauling.
Smooth Ride Over Bumps: Progressive Load Control
Road dips and uneven cargo don’t have to mean a harsh ride. The progressive load control design lets the springs compress easily for lighter loads, softening bumps and vibration. As the load increases, the springs firm up to provide solid support, helping to prevent bottoming out and keeping your truck balanced no matter how much weight you’re carrying.
Stay Steady in Crosswinds and Turns: Independent Spring Action
When a curve or crosswind tries to throw you around, each spring works on its own to keep your truck stable. This independent movement helps reduce body roll and sway, especially with off-center loads or when turning sharply. You’ll feel more confident and in control when driving through wind, traffic, or uneven terrain.
Built Tough to Handle Real-World Conditions: Durable Microcellular Urethane
These helper springs are made from microcellular urethane that resists oil, salt, UV rays, and abrasion. They perform in temperatures from -25 F to 200 F without losing strength. With minimal lateral expansion, the springs compress straight down instead of bulging out, so they fit safely in tight spaces and hold up under constant use.
Install It Yourself Without Hassle: Simple No-Drill Setup
Adding extra suspension support doesn’t have to be complicated. The SumoSprings replace your existing bump stops with a simple bolt-on setup that requires no drilling or airline routing. Once installed, they’re maintenance-free—no air pressure checks or adjustments needed—just dependable load support every time you hit the road.

Video Transcript for A Closer Look at the SumoSprings Solo Custom Helper Springs-SS37PV
Hi everybody, Andy here with etrailer.com, and today we're gonna take a look at the Sumo Springs rear axle solo custom helper springs. These are designed to fit your 2016 and newer GMC Canyon and Chevrolet Colorado, then your 2016 and newer Toyota Tacoma, then your 2005 to 2015 Toyota Tacoma Pre-Runner and excluding Pre-Runner. Now as you know, towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that your 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. Now Sumo Springs upgrade your vehicle's factory suspension to level your vehicle, improve driving performance and keep your ride comfortable.
These 1,800-pound capacity helper springs provide progressive load control. The more you load them, the stiffer they become, and with the 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% to support a heavy rear load, and to help your factory suspension bear up under the load. This is going to even out the weight which levels your vehicle and ensure that your front tires are making better contact with the road.
A level ride means that you have improved driving control. It ensures safe headlight aim and it helps to minimize sway. The springs also supports your factory suspension, which helps prevent sagging and reduce bottoming out. Now these springs work independently from one another to support each side of your vehicle. This action helps reduce body roll when you make a sharp turn, and this also helps compensate for off-center loads.
These microcellular urethane springs are tough. They're going to resist abrasion, oil, salt and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from negative 25 degrees Fahrenheit to 200 degrees Fahrenheit. These springs will 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, Sumo springs require no maintenance or adjustment. Now these helper springs are made here in the USA and are custom design as I mentioned earlier, to fit your vehicle.
They install easily with no drilling required. And as you can see, this includes everything that you see here on my table before me to for a complete installation. The weight capacity at 50% compression is 1,800 pounds, and these Sumo Springs will not increase your vehicle's weight carrying capacity. So you do want to be aware of that. They do have a limited lifetime warranty. Instructions are included to walk you through the installation process. And that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

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.

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.

2025 Promaster 2500 159” wheelbase. Backed the van on couple 2” X 6 “ easier sliding under. Sprayed PB Blaster on top of bumper spring, using a 16” Channel Lock, easy off with the old. 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.

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.

Have Nissan NV 1500 (transit van).Loads and trailers were the problem-along with the constant "slouch" look-with no really heavy load on it. Hated that!
These used with "add-on leaf springs" made a world of difference.
Bumps being felt, are there, but nothing like before. These two things along with new shocks (all for back),has helped out so much!
So, the bumps have almost faded to "nothingness". Now granted, I have not hit a massive pothole, yet. I try to dodge those anyhow!
Components work great together!

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.

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.

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 recommend the SumoSprings Solo Custom Helper Springs item # SS37PV. These helper springs replace your rear bump stops and will provide you with an additional 1,800 lbs of support. SumoSprings work off a system called progressive load control. This means that the heavier the weight is on the rear of your truck the more the springs will engage.
