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.I installed these on my stock 2019 Outback hoping it would level out the rear sag when towing small teardrop trailer. Man, total game changer! Towing was fine prior to install but didn't like my headlights pointing up with rear sag.
Installation was fairly easy. I say fairly because on my Limited the springs didn't allow much room. It required using a flathead screwdriver to get them seated. Took about an hour and most of that was lifting behind removing wheels. Feels and looks 100% better without the need for new overload springs. Highly recommend
Before and after photos. One with skybox is before
The product itself was the best quality I could expect.
The website on the other hand repeatedly assured me this would install on a 2015 Honda CR-V. Which it will not.
I tried it myself and also took the vehicle and parts to a mechanic in town and all persons involved with the garage agreed this wouldn’t be a good idea to install.
The spring helpers could be jammed in around the struts but would rub and bind on the inner body of the vehicle.
The short answer here is the rear suspension on my vehicle has struts not plain old coil springs not to mention the clearance lacking the install.
The appointment with the mechanic was a couple months out and took me past 30 days for a return of the product so I still have them rolling around in my trunk.
Not the best experience overall.
Absolutely not worth it at all... Initially great but after 15-20 min of load the rear sunk back down to where it was and the sumo spring never recovered. I ended up tossing them and buying a set of coil springs from Ralitek. Do not waste your money.
I have a 2015 Subaru Outback. When towing it went from a mushy rear end to a nice stiffness. Max tongue weight is 275# and with 220# on a recent trip (~2000# trailer weight) it only squatted the rear end about an inch (after rolling back and forth to let it settle).
Previously I was getting instability above 60mph especially when hitting the bumps at the ends of bridges. On my recent trip I was able to hit 80mph with the car feeling totally planted.
When totally empty you do get just the smallest hint of a 'truck like' ride but I typically carry some tools and other stuff all the time and that dampens it.
For install I found it helped to sort of feed the sumo into the coil as you kinda roll your hand over the part juming into the groove.
Installation was a bit more difficult than anticipated, however, for an 81-year-old guy, most everything is. The SumoSprings work just fine. I feel like they've reduced the sway and increased stability while hauling our Tab320 trailer with our Subaru Outback. Service from eTrailer was fast.
Did not fit the 2022 Subaru Outback as advertised making these a total cash grab on etrailers part. Buyer Beware. Incorrect fitment guide means expensive mistake.
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.

Ive kept them installed for the last year and the cars ride quality has never suffered. Great product!!
Would have been great, if they lasted longer than 4 hours.
I installed these on my 2019 Crosstrek, to haul a dirtbike on a hitch mounted carrier from Oregon to southern California. Without the bike and the helper springs installed, I barely noticed a difference while driving. With the bike loaded it gave me a couple extra inches of more clearance, so I was ecstatic.
I checked to make sure they were in place when I left town, only to find them half falling out by the time I made it to central Oregon. The Subi was loaded down so I couldn't get them back into place and had to just pull them out for the rest of the trip.
And no, mine did not come with holes to zip tie them. So I guess I'll give that a shot before I toss them. The instructions never said I'd have to punch holes and zip tie them to stay in place.
False advertising that they'd stay in place without being tied in. Pretty disappointed in this purchase.

Hey Bree. That is definitely not the experience we want you to have, especially on a long trip. I do have to agree that I do miss the hole and zip tie they used to have. It seems that you may make your own holes and add in the zip ties, if you decide that you do not want to go that route, let me know. There is a 30-day satisfaction on all SumoSprings products whether they are installed and used or not. The last thing I want is for you to feel like you're stuck with a product that you just do not like.
I used the Sumo Springs on a 2014 VW Passat TDI SEL in the rear. I like the product, my car always had that overloaded look I tow a small trailer and the car's suspension was to soft.
The Sumo spring Support works great on my car the car came up about half inch and under load it gives the needed support I was locking for.
I also like that I have not to mess around with any air adjustment and it tis maintenance free.
The install was easy and I was done in about 45 minutes. The toughest part was to cut it for the instructed length for my car.
Installed sumo springs on my 2007 Toyota Prius. They installed fairly easily in about 15 minutes per wheel. I had to trim approximately 3 inches off of each sumo spring. I used ivory soap bar to lubricate the springs before install. The rear of the car was raised maybe 2 inches as a result. I do not notice any adverse changes in the handling of the vehicle when not loaded. Moving cross country soon and need to load up vehicle so not bottoming rear springs. overall very pleased with the product. Received Quick delivery of product from etrailer.
Not easy to install. Took to a trailer shop for installation. Seem to stabilize my vehicle when towing, haven't towed after dark yet to see if oncoming traffic flash their lights at me.
Installed pretty easily. The trick is to start at the bottom of the spring and push it up. Didn’t need to apply any soap but springs were pretty clean to begin with (38K miles). The kit did not come with zip ties even though the etrailer description says it should, but the Sumosprings documentation clearly states they are not included.
They were very easy to install. Yes I use the instructions. They help keep from blinding people from my headlights when I have people in the rear seats. Great product.
These installed in the rear coils, gave my Outback the exact amount of rake I was hoping for.
They were nice for a while, but came out while driving under normal conditions. Lost one down the road. Even used zip ties. Your best bet is screw in coil spacers. They won't come out.
They did buffer the spring compression but they were notably more difficult to stay put than expected. These didn't come with a slot for zip ties so I had to make my own. If you're like me and wanted to cheap out on new spring coils for a short term use application it'll get the job done.
Sumo Springs are working well so far. Using these on a 2008 VW Passat. It keeps the back slightly higher with a heavy load in the back or a trailer attached, so it's less frequent that I scrape the trailer Hitch
Awesome! I would suggest anyone with a mid sized SUV to use them if you do road trips. Packed folull with a motorcycle it this made it far more manageable and far safer on the road. Better control and less float.
Installation wasn't too bad but it's a tight fit so use plenty of soapy water and be patient.
Package arrive late and was missing ite ms.
I installed the Sumo spring helpers on a 2018 Subaru Outback. The installation was straight forward and took me less than an hour. The installation with this model car is tight and at first I didn’t think the helpers would fit because of the shock boot cover and the wheel well molding. However, you need to work the helpers into the springs at the bottom 2 turns, cut with a buck knife, fasten a zip tie to each end and then thread the helper up the springs to the top 2-3 turns as stated by the instructions. A little tip that made my install easy was to cut the leading top inside edge, 1/4 inch or so, at an angle. This enables the leading upper back edge to easily slip under the spring and then it is super easy to work the remainder in place.
The helpers seemed to lift the back end about 1.5-2” and the ride is so much better since the back suspension is firmer and doesn’t bounce so much on bumpy roads. I tried it out on some speed bumps also, awesome!.
I should have taken before and after pictures but was in a hurry to get the install done and load the car for a nomad camping adventure. My reason for wanting to install the Sumo helpers is because we recently took a trip to Bears Ears,UT and had to carry 30 gallons of water, with a hitch cargo box and the Outback fill road. ed with essential camping gear. The load was within Subaru weight specs but the back end was definitely sagging and driving at highway speeds was a bit nerve racking. The car is loaded again, albeit with everything except only 2-6 gallon jerry cans, and the back looks and feels much safer. I would highly recommend this product to solve the back end sag and unsafe bounce when carrying weight in the middle to upper range of Subaru weight specifications.
I will get pictures next time I have the tires off but had to load and hit the road.
My question is why are the Sumo helpers only recommended for the rear?

These are designed to help support the load of the rear especially when towing. When towing some vehicles experience rear sag and these help support the weight to keep the vehicle level.
Easy install in 15 minutes. It did help with sag and I noticed an immediate difference on the positive side. I installed these on a Honda Pilot used for towing a small Teardrop trailer. I am using these in conjunction with Timbren bump stops and am pleased with the results. I was going to install airbags but did not want the hassle of checking air pressure and these being maintenance free was a good option.

did this help level the rear of your pilot? My sags

If you want to help with sag I suggest putting in air bags. The super springs do help but air bags will let you adjust height about 1 to 2 inches.

If you want to level out your Pilot try Airbags from Firestone or Ready Lift. You can adjuct hieght about 1 or 2 inches. I installed the Ready Lift 2 inch lift kit but still might do the airbags down the line but I am happy with the Super Springs and lift kit!
Very little difference when driving. When loaded it makes a big difference! Thanks!
Seem to do what they say, my Subaru’s suspension seems a bit firmer when under load from my boat.
Performed as expected!
Helped stabilize my Outback while towing. Noticeably less bouncy.
Do you have a question about this Vehicle Suspension?

I can definitely look into this for you. Can you tell me in more detail how they are not a fit? Would you be able to send a picture?
