800-lb Capacity. Upgrade your Ram 3500's front suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
A heavy front load, such as a snowplow or a winch, can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a 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 percent to support a heavy front load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your rear tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings 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, SumoSprings require no maintenance or adjustment.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at the SumoSprings Solo Custom Helper Springs for your front axle. Now this is a custom fit part. It is designed to fit the 1994 to 2010 Dodge Ram 2500 and 3500 four wheel drive trucks, also fits the 2011 and newer Ram 2500 and 3500 four wheel drive trucks. And on a custom fit part like this, I always like to recommend for you to go to our website.
Use the fit guide, put in your year model vehicle and it'll show if this'll work for your application.Now these helper springs will upgrade your vehicle's front suspension for improved driver control and comfort. They'll support any heavy front end loads to keep your vehicle level and they'll help to absorb bumps and shocks, help minimize sway. They do offer progressive load control, which means the springs will compress according to the weight of your cargo. So if you have a lighter load, the springs compress easily at first for a nice soft engagement and less bumpy ride. And if you have a heavier load, the springs will compress by as much as 80% for support.
These springs do work independently from each other to compensate for off center loads, help reduce body roll during any sharp turns. And they are made of a durable microcellular urethane. This urethane will work in temperatures from negative 25 degrees Fahrenheit up to 200 degrees Fahrenheit and this will resist damage that can be caused by oils, road salts and UV rays.They do offer minimal lateral expansion, meaning the springs will compress vertically instead of to the sides so that they aren't easily damaged when operating in tight spaces. And of course they are maintenance free. There's no tubing to run or air pressure to monitor like with air springs.
These are a simple no-drill installation. Basically after removing your factory jounce bumper from the vehicle, these will install into the factory jounce bumper retaining cup. It does come with a nice set of instructions that'll describe how these do install. Does include the two jounce style springs. If you notice, one of them has a notch to it.
That is for the driver's side. That will tell you that in the instructions.This part is made in the USA. A few specs on this, the weight capacity at 50% compression is 800 pounds. And a note, these SumoSprings will not increase your vehicle's weight carrying capacity. But that should do it for the review on the SumoSprings Solo Custom Helper Springs for the front axle.

800-lb Capacity. Upgrade your vehicle's front suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.Excellent customer service as always. I do wish the reviews would be more consistently reviewing the specific item you select...sometimes I end up reading a bunch of irrelevant reviews for products that are merely "similar", but NOT the same.
Do you need to put a reference between your part number and the manufactures part number that you are getting the right part all the pictures are in black-and-white on the website the parts are blue in this case but nothing to tell you that you have the right part had to call and check out the numbers
It feels like it took a of the roughness out the bumps and washboard dirt roads
To make it simple, it was the easy to install! It took about 15 minutes to install both helper springs.

I see that you gave your experience with etrailer 2 stars. If you give me more information about why you are disappointed in us, I will be happy to assist you.
Easy install and think they will help on long road trips with the camper
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.
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
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 !
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.
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.
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!
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.
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.
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.
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.
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!
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.
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.
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.
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.
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.

I have experienced a much better ride when not towing. I boon dock a lot and keep my 150 gal. bladder in the bed. The springs reduce the bounce on the front when a heavy load is in the bed which is the normal function and it is a noticeable difference from preinstallation.
