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.

2018 Honda Odyssey

Great quality and fast delivery. The only problem I had was wether to install the 1 inch spacer. On my 2018 entegra odyssey ( jayco ) I didn’t need the spacers.


The installation was simple and easy to complete. Ratcheting box wrenches (14 & 15 mm) would have made the job a lot easier but standard tools did work. The instructions were missing some useful information regarding the mounting holes and spacer use. I will follow up this post with a report on how well the RV rides with this upgrade after the next few trips. I will reserve final rating until I test drive.


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.

2019 Ford E-Series Cutaway

Made the ride much smoother and steady


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.


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).


I have received but letting my local RV place(Monkey RV) in Manteca, Ca. to install them. Then it will be a great different ride feeling. Thank you

2018 Jayco Greyhawk Motorhome

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.


Really helped with the rocking and improved driving control as a result. Added front sumos as well.


Good ride now!

2022 Ford E-Series Cutaway

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


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


Worked good but had to modify to fit right the part # is not the right fit for 2013 Ford e 450 class c manufacture agreed when I call tack support


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

2022 Ford E-Series Cutaway

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

2001 Dodge Ram Pickup

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.

2017 Ford E-Series Cutaway

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