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.

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
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.
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 items worked great! Easy to install as the video guides helped a ton!
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.
Brian M - 03/25/2015Coil 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.
These work really well to keep the back end of my Subaru Outback from dropping when towing my 5x10 trailer.
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.
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
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.
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.
Harold - 08/11/2022These are great for increasing the stability of my car when I'm towing my boat
Easy to install, took about 15 minutes.

Works exactly how I needed. The Ride is still very nice. There's about 350lbs with the weight of the box & rack. Suspension in the rear used to sag a bunch, even with a 2" suspension lift.

About all I can say for these is that they did raise the back of my Expedition EL about a 1/2". However, they didn't stay in place for even a year. As far as helping the ride of the truck with the travel trailer, I *think* it helped, but I really don't know if it is anything more than the placebo effect. I removed them before having Bilstein 5100 series shocks installed, with the spring collar set to raise .4", which did make a noticeable, positive difference in the way the truck handled when towing.

Installed the CSS-1168R Coil SumoSprings Custom Helper spacers on a 2011 Honda Ridgeline 4 wheel drive rear springs. Installation took about 45 minutes including removal of tires. Once spacer was started the installation was easy.
Zip ties were a little more difficult because of the dust strut covers installed by Honda.
Thomas - 09/20/2021Review from a similar SumoSprings Coil in Vehicle Suspension
Took a chance and ordered rears for my 2021 AWD Pacifica even though the AWD model wasn't listed. After cutting a couple of inches off they fit perfectly! Coils are tight so you'll need to unbolt the bottom shock bolt to gain an extra inch of decompression. Once installed there's no difference in ride hight or ride with the van unloaded. Once loaded up it gives the extra support needed to prevent scraping my muffler pulling in and out of driveways. I know this mod voids the warranty, but it was a chance worth taking.
Review from a similar SumoSprings Coil in Vehicle Suspension
This one year review. We have a 2018 Mercedes Metris, it's just a big mini-van, but not a sprinter. The suspension is fairly soft, ok for city driving, but a little soft for 70+. When hauling a trailer we would gently sway, not great, so we got the rear set and it helped quite a bit, we followed with the front set 3 weeks later.
Overall it firmed up the suspension enough to really help without it being too firm. It raised the stance about 1/2" and is relatively easy to install.
Would buy again.
Review from a similar SumoSprings Coil in Vehicle Suspension
Did a great job helping with squat and not impacting unloaded ride quality. I have these installed in my 2019 Ford Expedition FX4 with a leveling kit so any sort of load really highlighted rear squat. I am pulling a 36' long 7000lb loaded travel trailer and I would consider these a must have. Install was pretty straight forward, take the weight off the rear tires, soap them up a little bit and they slide in with a little effort.
