Get the cushioning power of SumoSprings for your coil springs and keep your ride comfortable. The wedge-shaped springs fit between the individual coils of your existing springs and help support heavy loads on your rear suspension.
Features:
Specs:
Insert these helper springs in between the individual coil loops in your rear coil springs to defeat driver fatigue and add better support for heavy loads. Most factory coil suspensions have a difficult time hauling added weight. The rear coils may struggle with supporting the extra load placed on your rear axle when you're towing a trailer or using a hitch-mounted cargo carrier or bike rack. If your coil springs are totally squished under a load, the lack of shock absorption can be harsh on your backside, especially if you spend long hours sitting in your vehicle while driving to your campsite.
Inside each helper spring, a core of microcellular polyurethane foam adds cushioning between your coils to make your ride more comfortable. Each doughnut-shaped spring has H-shaped channels at the top and bottom that fit to the rung of an individual coil in your rear coil springs. The cushioning absorbs shock, but also works progressively to better support weight, keeping your truck level.
Unlike air springs that fit inside your coil springs, these polyurethane springs require no air pressure monitoring, and they are easier to install. Say goodbye to air lines, valves and air tanks and hello to maintenance-free suspension support. Unbumpify your ride with Coil SumoSprings for coil suspensions.

Get the cushioning power of SumoSprings for your coil springs and keep your ride comfortable. The wedge-shaped springs fit between the individual coils of your existing springs and help support heavy loads on your rear suspension.The Sumo Springs installed easily and definitely hold up the back of the vehicle better and also firmed up the ride , now I want them for the front also. Great product!
The installation was quick and easy. I did remove the tire to ease in the installation, it just made it easier for me. It took longer to stage the pictures for the review than install them. I took a measurement I think I gained a 1/4 to 1/2 inch in lift and doesn’t seem so floaty
The instructions, well!! lack a bit of detail. My first instinct was to return them . I called the manufactures tech line ,and got the 10-36 asap.
........ after that the install was a breeze !!
I am in the opinion these helper springs will stiffen the rear coil enough to balance a heavier tongue or small trailer weight.
The SumoSprings are just whet we needed. Just that little bit of extra space to pull our UTV trailer without bottoming out.
These coil spring spacers are extremely easy & quick to install. Happy to find these for my 2009 Mercury Grand Marquis.
Under most conditions the springs do not compress enough to be needed, but pulling our pop up camper with our Kia Soul, they smooth the ride and keep us level
Etrailer customer service is always excellent.
This product installs easily and quickly and performs as claimed. Provided just enough additional compressive loading resistance in conjunction with the rear struts to prevent bottoming out while towing a lightweight pop up camper. Quick fix for folks hauling something with 100 pounds or less of tongue weight.
Tips: 1" overlap worked best on my Subaru. SumoSpring elastomer cut easily and accurately with a band saw. Knife works but the elastomer is slippery and the cut is less than accurate.
As you push the zip ties through their holes put an index finger under the hole on the inside and direct the end of the zip tie upwards to make it easy to retrieve. Make zip ties snug but not so tight they distort the geometry of the elastomer.

Continue to be pleased with the SumoSprings on our 2005 Subaru Outback. The alternative was to spend $800 for new heavy duty rear struts. They work well to prevent bottoming out when towing a camper and dont seem to effect the overall ride quality when not towing a trailer.
We purchased these for our Outback about a year ago. They definitely improved the ride when towing our tear drop trailer, especially over the “washboard” sections of I80 in PA, and some of the logging roads in northern Maine. Our mechanic complimented us on the choice as well. Not needing a total suspension upgrade, these helper-springs are a great alternative for an improved ride for small vehicle lite/medium load road hauling. We’ve made several purchases from e-trailer – these hit the mark like everything else.
These were exactly what My Husband was having a hard time finding.
Coil SumoSprings for a 2008 Honda Fit Sport. I ordered the correct springs based on etrailer's website and when it came time to install them, we discovered they were too big. I called etrailer customer service and was fortunate to be connected to Natalie L. Natalie was patient and after a couple of calls, found the springs that work for my vehicle. Natalie updated the website to reflect the accurate part number. Natalie, thank you for making the return process painless. Your customer service was outstanding, Natalie. As an aside, it's difficult finding and keeping good employees. I'd do what I could to keep Natalie.
The replacement springs have been installed and working as expected.
Installed this on my 2013 Diesel Cayenne as I put larger tires on it and when hauling trailers it bottomed out. It still does from time to time, but it has been drastically improved.
These work really well to keep the back end of my Subaru Outback from dropping when towing my 5x10 trailer.
Just installed them on my ‘11 Subaru Outback and they appear to function well over 1 short trip. I was initially concerned as following the instructions demanded I trim almost 4” off of them, but a tech at the manufacturer stated it would be fine. I did and installation was a breeze
Easy Easy Install
Great directions
Done in minutes
Did remove the rear wheels
Cause it is easier
Can't wait to see how they work with a trailer on my Subaru XV Crosstrek
These items worked great! Easy to install as the video guides helped a ton!
For me it's dont seem to make a big difference. Maybe if i double the kit I will fill it. But it hold nicely in place, they are in place about a year now and the tirap do the job. It's easy to install. But for the price I will figure to replace the coil spring by stronger one.
These are great for increasing the stability of my car when I'm towing my boat
Arrived sooner than expected, installation was simple and quick. It seems as though I will havean additional 1” of lift. Looking forward to trying it out on a trip.
It fitted on my Forester 2015.

Do these work well towing a 2200 lb work trailer hauling a moderate load with a 03 tahoe
