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.


Installed spring when it is not compressed

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.


Installed spring when it is compressed

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.

After buying sumo springs for the front of my 2021 Jayco Greyhawk 30Z. I liked them so much I decided to buy them for the rear. It took me 10 min to install them. It’s an awesome improvement in handling and they work well with the stock springs. They only took 3 day from order to delivery. Just when you think customer service is dead your team did a great job. Thank you and I highly recommend these Sumo spring to anyone with a Class C motor home.

Best investment I’ve made in my RV. Only took an hour to install and that included prep. I immediately noticed a change in handling. Outstanding product

Excellent for 2016 Thor Vegas rear axel. It's a must have modification!

Good ride now!

I've had these Sumo Springs on my 2018 Thor 26HE Class C with standard sway control for over a year and immediately after I installed them I noticed a huge difference, like night and day. I installed them myself, it was easy but took some time because I had to use a floor jack and blocks for the rear, the front went in very easy. A definite must have. I'm not sure I even need to upgrade my sway control like I originally planned.

They were very easy to install and did make a noticeable difference in driving just one of the improvements to improve driving

RV Class C Jayco Redhawk. Easy install. No Jacking. great ride improvement.

As Always excellent pre-sale support from E-trailer. I wasn’t sure these would fit my 2018 Jayco Greyhawk built on a Ford E-450 chassis. I emailed to confirm and got an immediate response.
I had my local mechanic install these and it took him about 1.5 Hrs. No issues, he said they installed easily.
Can’t wait to take the rig on the Interstate to test it out. I did drive home locally after the install and I can’t say I noticed a huge difference.
Thanks Etrailer.

Was easy to install and works very well. In conjunction with the steering stabilizer made driving our Ford Class C much more pleasant (especially when going over big bumps).

Installing these babies in the morning. Very pleased with this product.

I got my order in three days ! I installed them immediately and took a test drive and could tell that they helped with the sway I had been feeling from big trucks passing me on the interstate.

Review from a similar SumoSprings Solo in Vehicle Suspension


I would have give it a 5star but the bolts are 1/4” I think it should be at least minimum of 3/8” or1/2” bolts to hold the sumo springs. I like them toed the camper handles very well. Wishi got these a long time ago worth getting. With out camper can tell that it’s there but rides ok. I wanted the same ride it not quite. I ask what the how high they are said 5” with bracket but it’s actually 6” with bracket see picture. I would recommend getting the sumo springs ssr-610-47.


Comments
They are working great in my 12 tundra still would recommend them. I tow 8000lbs camper handles great at times I probably wished I got the next step up but might be to hard when not towing. Will see next time I need to get some for next truck. Wish they have measurements to know how high they are from the lighter ones to the heavier ones.

Review from a similar SumoSprings Solo in Vehicle Suspension


2015 Frontier Crew cab Desert Runner (purchased the yellow Sumo Springs). Easiest install ever! 18mm deep socket and long breaker bar for breaking nuts loose. Removed factory bumpstop, install sumo bracket and retighten U bolts to 58 foot pounds. After installing both brackets, lifted back of truck up 4 inches to install sumo spring with blue lock tight on bracket bolt, tighten sumo spring onto bracket and lowered truck off the jack. Overall it raised the back of my truck bed 1 inch. Ride is stiffer with no bed roll in the turns. Loaded my 24 foot travel trailer with load leveler- equalizer bars and gained 3 inches (less “squat”.) Truck is level now vs nose high (without the sumo springs). Definitely an upgrade that was needed in 2015 when I first bought the truck!!!


Comments
Yellow for the super heavy load and daily driving I have the black middle weight springs. Easy swap out when I need the yellow Heavy Duty.

Review from a similar SumoSprings Solo in Vehicle Suspension


I just finished installing the Sumo Springs to my 2020 Ram 3500. The install was super easy. Instruction were easy to follow and the whole thing took less time than I thought. I won’t know how they perform until I pull the 5er out of storage this spring, but I am ready. My only question and the reason for 4 stars instead of 5 was I thought they would sit closer to the axle than they did, may 2” from axle and I would have liked may 1” maybe I could have used another spacer and longer flat head screw to bring it closer but we will see when I put the weight on the truck. I included picks if someone wants to give me their opinion. So far I am really happy with them.


Comments
Fantastic, the Sumo’s are working as promised. Helps with sag, smooths out the ride and provides support from sway. I couldn’t be more happy. This year we will be adding Sumo’s to the 5er to help in the back, super excited about this upgrade.

Made towing TT with my Toyota Tundra much better. My camper has a tongue weight over 900 pounds. Made bridge crossing and overpasses much smoother.

Review from a similar SumoSprings Solo in Vehicle Suspension


Parts arrived on schedule. At first I thought that the parts did not fit my truck, so I called customer service and they immediately started to send me a return label and refund. It turned out that I was wrong, and the parts did fit. I called them back cancelled the refund action.
Great friendly service!
I also found that the price I paid was much cheaper than [online store]. I highly recommend etrailer!


Comments
The springs still work as they should. They are nice because they dont seem to affect the ride quality when the camper is not on the truck. Very happy with my purchase.

Review from a similar SumoSprings Solo in Vehicle Suspension


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.


Comments
One year and working better than I imagined it would. Carrying loads in my Tacoma is no longer an exercise in fear and my shocks are way happier happier with a little help!
