Features to know about
Stay Level and Confident Under Load: 3,000-lb Rear Suspension Support
Heavy trailers and bed loads can make the rear end sag, throwing off steering and braking. These SumoSprings Rebel helper springs add up to 3,000 lbs of support at 50-percent compression to keep your ride level when towing or hauling. They absorb bumps and shocks, help your factory suspension carry the weight, and keep your headlights aimed where they should. With your truck sitting level, you get steadier handling and better traction under load.
Smooth Ride When Empty or Rough Roads Ahead: 2-Piece Progressive Design
The 2-piece design separates when unloaded so your suspension can move freely for a smoother ride. When cargo weight goes up, the pieces meet and compress to provide the support you need. The progressive load control means light loads engage softly while heavy loads compress up to 80 percent for maximum support. It’s a setup that feels comfortable when empty and solid when fully loaded or on rough terrain.
Stay Steady in Crosswinds and Turns: Independent Spring Action
Each spring works on its own to handle uneven weight and reduce body roll in corners. That independent movement keeps your ride stable through crosswinds, sharp turns, or uneven ground. Whether you’re pulling a camper or carrying gear, the truck feels more planted and predictable on the road.
Built Tough for Long Hauls: Maintenance-Free Microcellular Urethane
These durable microcellular urethane springs handle temperatures from -25 F to 200 F and resist damage from oils, road salt, and UV rays. They compress vertically with minimal side expansion so nearby parts stay clear even in tight spots. There’s no tubing or air pressure to maintain—just a bolt-on design with included hardware that keeps performing trip after trip without extra upkeep.

Sumo rebel Springs are in contact with each other when unloaded. The factory overloads are still 3 inches from touching the frame supports. This is not what was advertised for this setup

I installed on 24 Silverado 2500hd. Install went great. They work well when towing. I haul a 32’ bumper pull camper. They help reduce the sag dramatically. When not hauling, the truck rides rougher than without them installed. That makes sense and I am happy with them. I may have went with a bit less stiffness now that I know.

Glad to hear it! I'm a big fan of SumoSprings because they're so easy to install and don't require any maintenance after. What kind of trailer are you hauling?

Product works very well. Only problem we had was an alignment problem on the drivers side spring. Couldn't get it completely centered top to bottom, but was close enough to still fit together.

The springs work great. After a year in service, they are like new. We use this truck as a rental equipment delivery truck. We pull a 26ft gooseneck tilt deck trailer that is 16K rated. The ride is great and the springs handle the load nicely with no sag when loaded. We have added these springs to all 6 of our 1-ton delivery trucks.

I put a small leveling kit in my 2500hd Silverado. I noticed afterwards towing my excavator or dump trailer I was getting some rear sag when I had my trailers loaded heavy. I considered doing air bags for the rear. Instead I installed the sumo springs. I installed them in about an hour. Very happy with them. No noticeable difference in ride quality while empty. And they keep my truck level when I’m hauling my trailers. 5 stars!

Just Installed my Sumo Rear Springs. They went in real easy on my Dodge Ram 3500. The thing that took the most time on the install was jacking up the frame 3-4" to make enough space between the axle base and top of frame to slip in the entire lower and top sections of the Sumo Springs. Once I did that, I narrowed that space by letting the frame down a little but not all the way. Just enough to catch the receiving spring and leaving a half inch gap between the two sections. This allowed me to easily rachet the bottom u-clap without a problem and keep good alighment. I know I'm going to love this product once I hitch up. No more 2' drop in the rear end once hooking up to my 15k 5th wheel. These springs are stout but no so stout I'll beat the hell out of my body when hunting the rutted roads of the great North West. Thank you Jessie for your expertise and steering me toward the perfect application to meet my pulling and off-road needs.

I wish I would have put on an air ride system instead. When I put my light (1750lb.)truck camper on my F250 truck, the back of the truck saggs. Not happy! I am sure the product is okay, just not what I wanted.

Still too new for me to review how the product works, but in terms of installation, I had a lot of issues with installation on my 2015 Ford F150. Everything I saw made it sound easy for self install by one person, but was pretty tough self install for me. I'm not an expert on vehicles, but generally pretty handy and I had trouble doing it by myself and took at lot of time.
Difficult parts were attaching the upper mounting bracket to the frame, and getting the bolt through a washer and into a mounting piece that I had to insert into the frame
Couple of notes. My truck is a 4x4 and the instructions said to mount the upper bracket in the bottom holes for 4x4's, but that was not possible as it wouldn't fit. After talking to manufacturer, they said it was ok to mount in the the upper holes that was supposed to be for 2wd models.
The instructions don't mention using lock tight on all nuts, but I had one the the sides come off and lost some pieces. After getting a warranty replacement, the manufacturer said to use lock tight, even though it wasn't noted on instructions man. They said in newer instructions, it adds that, but that wasn't included in the product I received
Hoping I will like the ride when I connect and use on my trailer and will reserve judgement till then

I haven't had the springs under load, yet. I'm sure they'll perform as expected. I was not able to adjust the driver's side springs so that they align correctly. (see pic). The bottom spring does go into the top spring, but it's off enough that over time it will be an issue. Passenger side is spot-on! I have a 2024 F350 Tremor

Ride is great unloaded. They don’t touch until you load the truck with a little weight. On a light trailer 16ft or 20ft car hauler they just touch. The ride may be a little stiffer in the rear since there isn’t much weight to keep them down or the bounce down. But it’s not bad at all. Hauling a heavy load where they get compressed the load is much more stable and the truck hauls the heavy loads MUCH better. Cheaper than air ride. No lines to run. No worry to inflate or deflate. I give them 10/10. Very nice product. If you run light loads more than heavy I would go with the blue or yellow versions. I have the 5k sumos on a 2018 Ram 3500 4x4

Adding a pair of SumoSprings to the rear axle of our 2015 F250 did little to help level the vehicle when hauling 500 to a 1000 lbs of feed or other materials. When pulling a bumper pull tandam trailer with a UTV, tractor, etc.,these springs did not hold the pickup level. We have since replace the leaf springs with OEM parts and all is better. The SumoSprings is a very good idea however did not solve our concern and probably should have saved the cost and replace the leaf springs first. Please note that this F250 does not have a goose neck hitch and it is rare to be overloaded. We use a one ton for those loads. Thanks.

These will not fix an already sagging suspension. These are designed to help support suspension but leaf springs need to be replaced they will not fix that much sag. I would recommend using some airbags, like part # F2703, in place of Sumo Springs. You will need a compressor, like part # F2097 for the airbags.

They fit fine and installed as described in the printed instructions. Reasonably easy overall, even for a novice like me. My only comment is that the video that was included showed a different set up than what was delivered. That made me unsure if I had the proper system for my truck, which indeed I did, but the difference between what was shown in the video that was "for my truck" and what was in the box had me wondering. Never-the-less, all was correct and went well.

Product is excellent. The springs really reduced the squat I used to have in my truck when I hooked up my fifth wheel camper. Actual reduction in squat was around a 2 inch change. This also keeps the nose of the truck from rising in response to the rear sag I used to have, which makes the overall handling of the total rig a bit better as well. Also, the ride, while connected, is noticeably smoother and feels more stable while driving in stout crosswinds, which we frequently enjoy, here in Oklahoma.

- Recommended Suspension Support That Is Not Air Bags for a 2024 Ford F-350 Hey Kent, thanks for the information.

The springs have a two piece design so unless you put weight on the rear end of your truck they will not engage. You're not squatting that much so these will do a great job of maintaining your daily driving ride quality while also keeping your rear end level...

The Rebel's 2 piece design allows for better compression and movement with the axle, giving you a better and more comfortable ride. The higher capacity, though pretty small, does also lend itself towards more heavy duty trucks, like your 2022 Ford F-350. This means they will suit your needs better and will be the better option.

The kit I recommend for your 2022 Ford F-350 4x4 though is the Rebel kit from SumoSprings: - SumoSprings Rebel Custom Helper Springs # SSR-128-40-2 The reason I like this over the Timbrens is because the Timbren springs tend to be less forgiving. While that initially sounds like a good thing for heavy duty towing, it also means you're going to feel it when you aren't towing. SumoSprings has done an excellent job at combining...

- Sumo Springs for 2020 F250 Tremor packageAccording to the folks at SuperSprings, the manufacturer of SumoSprings, the Rebel # SSR-129-40-2 IS compatible with the Tremor Package, as long as your truck does NOT have the 3 inch blocks on top of the overload springs. If you have the 1 inch blocks, the # SSR-129-40-2 will work perfectly. If you click the provided links, you can see some informational videos about the SumoSprings Rebel helper springs.

Hey Steve. Thanks for the feedback. This Rebel kit is designed for vehicles carrying variable heavy loads, so some contact at unloaded ride height can be normal depending on the application. If this is a dually, keep in mind this particular kit is intended for commercial applications only, where earlier engagement helps support the heavier loads these trucks regularly carry. I’d still verify the brackets and spacers match the instructions, but the Sumos contacting before the factory overloads does not automatically indicate a problem with this setup.
