When heavy loads or trailers push down the rear of your vehicle, it can throw off steering and braking. These SumoSprings Solo helper springs add up to 1,400 lbs of support at 50-percent compression to keep your ride level and steady. They absorb bumps and shocks while helping your factory suspension carry the weight, so your handling stays predictable and your headlights stay aimed where they should.
You don’t want a stiff ride when you’re running light, but you need firmness when the weight piles on. These helper springs use progressive load control — compressing easily at first for a softer ride, then stiffening as the load increases. They can compress by as much as 80 percent to support heavy cargo without bottoming out, keeping your factory suspension from wearing out under strain.
When a curve or uneven load tries to shift weight to one side, each spring works on its own to keep that side planted. This independent action helps reduce body roll through turns and keeps off-center loads from making the vehicle lean or sway. The result is steadier handling and better control when you’re towing or carrying gear.
Forget about air lines or pressure checks — these one-piece urethane springs are completely maintenance-free. The microcellular material resists oils, road salts, and UV rays, performing reliably in temperatures from -25?°F to 200?°F. They compress vertically with minimal side expansion, so they fit snugly in tight spaces without rubbing nearby parts. Once installed with the no-drill mounts, they’re ready for years of smooth, stable hauling without adjustment or upkeep.

looks like good quality and easy install , haven't towed with it yet , seems like it should work well .
Installed these on my Jeep Gladiator to help with pulling my camper trailer they have performed as expected
Amazing! I love these things! They keep my truck from squatting loaded.
Very easy to install
Great products and great company Etraioer gets it done!
so far good product
Ordering was easy and Sheila was very helpful. The Sumo Spring was delivered quickly. I have not installed them yet well do when it warms up. I am sure they will do what I want them to do. I will do a follow up after I install them.
Easy to install. Nice functionally upgrade. Happy with product. Let’s see how long will last.
These spring helpers perform as they should. Install without lifting vehicle.
My truck swatted really bad with the camper hooked to it but with the sumosprings it didn’t! Excellent product I highly recommend
Keeps my gladiator from sagging when I tow, I do wish that I had got the stronger ones but I will repurchase when finances allow??

Glad to hear they are helping, Barron! I get wanting to step up to the heavier ones as well, but hold on to these when you are testing them out. Sometimes they can make your unloaded ride kind of harsh. What are you typically towing?

These worked as advertised. Thanks!
I Installed the SumoSprings in less than ten minutes and was on the road with my box trailer (overloaded as usual) The helper springs made a significant difference in the way the Gladiator handled.
I give them a 10.
And I Loved the prompt delivery!

Awesome, Tony! Whatcha hauling in that trailer that's overloading you all the time? :)
I put them on my Jeep Gladiator Mojave which has a soft suspension. I have drove from Ohio to Florida with a camper attached and let me tell you, what a difference.!! The ride was so much cleaner.!! I could tell because I have made this drive twice without sumo springs and now once with them. I’ll tell everybody how well these work!
Incredibly easy to install and they perform as claimed. I had a terrible experience with the blue air bags that were difficult to install and then failed. The Sumosprings don’t offer the adjustability but they make up for it with ease of install and effectiveness.
Excellent! My son installed them in about 2 minutes on my 2025 Jeep Gladiator. He never even had to jack the truck up. Took off the old put on the new. Very impressed. Still need to test them with my Travel Trailer

Wow, does your son need a job as an installer!? 2 minutes has to be record time. It looks great Patrice! What kind of Travel Trailer do you have? Would love to hear how the springs perform when you take it out.
Easy to install and immediately noticed an improvement in ride stability and towing with my Gladiator. If only I had found these sooner.
Put these on a Jeep Gladiator to haul a motorcycle to Sturgis. Kept everything level, good ride and stability. Highly recommend.
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.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?
