Rear Suspension Support
Towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that the 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. 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 rear 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 front 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.
Durable, Custom-Fit Springs
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.

Absolutely a terrible product, I installed the SumoSpring into my truck and pulled my work trailer and the ride is terrible, The suspension hits hard on the Sumospring and is a unpleasant ride. Hopefully etrailer will refund my money..
by: Billorgan11/03/2022
It's okay, How ever I bought the Sumospring kit from this company, come to find out etrailer does not back up anything they sell, I was pushed off to the manufacturer of the product.

We cover the warranties on the majority of the products that we carry. There are manufacturers who prefer to handle the warranties directly with the end purchaser of the products. They are able to provide a faster solution this way.

Pulling an unloaded trailer causes the truck to shake like the tires are out of balance at 45mph to 50mph. 20ft 14GVWR 3000 lbs. Must be just enough weight to engage springs.
Put a load on the trailer and the springs work well. No rear end squat. Not harsh ride.

I've installed at least 4 sets of these springs on 4 different trucks and they really do a nice job carrying a load and the service from etrailer can't be beat

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 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.
by: Tony04/08/2023
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
by: Dan08/01/2023
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.
by: Thomas07/09/2022
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!
by: William01/13/2024
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.
by: Kenneth02/22/2023
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.
by: Zach01/24/2024
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.
by: Curt03/16/2024
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.
by: Darryl 03/06/2023
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!
by: Preston08/22/2022
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.
by: Roadtrek Installer01/04/2022
First off, these won't fix worn out suspension components, they are designed to improve ride quality by reducing sag/porpoising, especially on heavier vehicles.
Our 2010 Roadtrek 210P (75k miles) is a great rv but essentially a big heavy tub going down the road. Has the tendency to lean and wallow front to back. New shocks and all suspension is good, as mentioned make sure that stuff is all in good shape.
Pics show the oem stops vs the SS stops. Big difference - you may assume ride gets harsh but not the case. The oem stops were very tired and didn't do much. The preload on the new SS stops is just about perfect - any weight changes are very progressive which takes the harshness out of the ride. I didn't really see any change to ride height either.
Road manners are improved, there's a bit more resistance to lean, but the main difference is that the front end doesn't try to change height as readily with the back end.
Not a big deal to install. Youbdont need to pull the wheels, just turn them side to side to get to the stops. Pop out the old stops and clean the retaining cups with a wire brush and some brake clean. I used syl-glyde on the new stops to help get them into place. I also used a crowbar under the stop to push it into the cup while making sure the 4 tabs captured the top of the stop. Final step was to lower the van and give it a drive, then check to ensure the fit was good. The key here is to clean the cup first and use a bit of lube on the new stop.
Very pleased and I'll be installing SS on the back end soon. Yup, they're pricey but they are good quality with a limited lifetime warranty.
by: Louis 04/17/2023
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.
by: Kris03/16/2023
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.
by: Stan10/30/2023
These springs are amazing! They helped tremendously pulling my landscape trailer with all my mowers. I picked up a tractor impliment that I would normally bring a trailer for, but decided to put these springs to the test. Couldn't believe how good my truck rode and handled with 780lbs at the rear of my bed! These springs have exceeded all expectations.
I will say that I initially put the spacer, but found it effected my ride to much so I pulled it. Afterwards it rides like stock.
by: Robert10/13/2023
These do not fit a 2006 ram 2500. As you can see in the
Photo the bolt holes are WAY off. It also does not sit over the axle tube. My only option at this point to use them is to make a 2nd bracket to bolt the helper too. Very disappointed.
by: Barry08/06/2020
We pull an off-road teardrop camper with our 2013 Toyota Tacoma and were looking for a little help with the rear end sag when we have that hitched plus putting some weight in the back of the truck (firewood, water, etc). Our Tacoma is lifted (2.5") but the lift kept the stock springs with an added Deaver leaf to help with the notoriously soft Toyota springs. However, with the shell and ~300 pounds of weight in the back, it still sagged, especially with another 250 lbs of tongue weight from the trailer. The Sumos have eliminated that sag, even with bigger loads in the bed, eliminated body roll (also notoriously bad with Tacomas) and didn't destroy the ride for day to day driving. There might be a slight bit more stiffness when hitting speed bumps, but definitely not bad at all. If anything, I would say it IMPROVED the ride and handling.
The springs themselves were simple to install, less than half an hour start to finish. Some reviews have said they were bumping the frame after installing but we had about 1/2" gap on both sides. The only "specialty" tool would be a torque wrench capable of 90 lbs to get it to spec.
We considered Firestone air bags but after talking with the reps at e-trailer, we decided on these and couldn't be happier. Reasonably priced (half the price of air bags), no maintenance, great customer service...can't argue with anything at all.

- Recommended Rear Axle Suspension Enhancement Kit for 2016 Ram 3500 with Slide-In CamperThe best no-hassle option for stiffening your truck suspension when it is loaded with your slide-in camper is a set of Timbren jounce springs. These and all other suspension enhancement options for your rear axle are shown on the linked page. These are relatively low in cost, easier to install than most other solutions and they will give you progressive resistance in the rear suspension when you need it. But they will otherwise not alter the ride when the truck is unloaded. I suggest the...

The heavier-duty # T94VR is more intended for use on severe service vehicles such as tow trucks and ambulances.

A light or medium duty just won't offer the support that you will need for this particular trailer. For SumoSprings the heavy duty part for your truck is # SSR-302-54.
