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.by: Trevor10/16/2021
2021 Subaru Outback Wagon
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.
by: Q04/25/2024
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.

2020 Subaru Outback Wagon
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.
by: Brian02/07/2024
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.

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?

2022 Subaru Outback Wagon
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.
by: Richard 02/07/2024
2022 Kia Telluride
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.
by: Leo05/20/2024
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.
by: Shane05/09/2024
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.
by: Richard11/07/2023
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.

2014 Volkswagen Passat
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.

2015 Toyota Prius
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.
by: KV05/02/2021
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.
by: Chris08/11/2023
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.
by: Lloyd05/18/2024
Performed as expected!
by: Joe 02/17/2024
Very little difference when driving. When loaded it makes a big difference! Thanks!

2008 Volkswagen Passat
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

2021 Subaru Outback Wagon
Seem to do what they say, my Subaru’s suspension seems a bit firmer when under load from my boat.
by: Nicholas 06/15/2023
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.

Helped stabilize my Outback while towing. Noticeably less bouncy.
by: Killian G.05/27/2023
2011 Toyota RAV4
Installed in a 2011 RAV4 V6 FWD, and they do a wonder for taking some of the roll and sway out of turning, and soften a lot of the bumps and jolts from poorly-maintained roads. They also cut down a lot of the "rearing up/porpoising" that comes from accelerating out of a stop with the FWD. It keeps the ride height level, as well.
by: Bruce 04/26/2023
2002 Honda CR-V
It took a bit of doing to get them on my 2002 Honda CRV, in the rear, bit it was worth the effort. Not sure how well they keep the car rear end from sagging but I definitely noticed the car is much more stable cornering. Hugs the road much better.
by: Scott 04/16/2023
Subaru Outback Wagon
We have had these on our 2021 Outback and they have been great. The car does not squat nearly as much as it used to when we put our utility trailer on it. There was also no difference in the ride without the trailer.

Did not fit vehicle despite website saying it was correct part. Got a 'not our problem' from both etrailer & sumosprings.

2021 Subaru Outback Wagon
Received these today, and they look as advertised EXCEPT there are no perforations between the upper and lower grooves for securing to the springs with zip ties. They were to go on our ‘21 Outback xt, but I plan on returning them. Hopefully they can be exchanged for a set with the perforations, and I can change to an excellent rating.

SuperSprings updated the coil springs and they no longer come with zip ties. They are designed to pop into place and are held there by the groove in the coil spring.

- Which SumoSprings Kit Fits 208 Subaru Outback WagonWe have confirmed with SumoSprings that the part # CSS-1125R is a confirmed fit for your 2018 Subaru Outback Wagon
view full answer... - Suspension Enhancement Recommendation for 2011 Mitsubishi OutlanderI have a suspension enhancement kit I can recommend for your 2011 Mitsubishi Outlander, the SumoSprings kit part # CSS-1125R, but there are no options from Firestone we can guarantee will fit. I wish I could say that the Firestone # F4182 would work for you but it's not a tested and confirmed fit. The Sumo Spring kit though will work great and wont' require you to monitor air pressure in air lines either.
view full answer... - Recommended Suspension Enhancement To Reduce Rear End Sag On a 2024 Kia TellurideI recommend installing the Coil SumoSprings Custom Helper Springs # CSS-1125R on the rear suspension of your 2024 Kia Telluride. These fit in between the coils to provide some additional support and help reduce sag. They require no maintenance or adjustment so you will not have any additional steps to perform.
view full answer... - Rear Suspension Enhancement To Reduce Rear End Sag On a 2024 Kia TellurideWe have a couple options for your sagging 2024 Kia Telluride. The first is the easiest to install and is maintenance free so you will not have do anything after you install them. They are the Coil SumoSprings Custom Helper Springs # CSS-1125R. These fit between the coils and provide additional resistance to keep them from compressing as much and reducing the rear sag when loaded. We also have the Air Lift 1000 Air Helper Springs # AL29PD which I feel are a better option. I prefer these...
view full answer... - Is OEM Hitch Fascia Panel for 2022 Subaru Outback Wilderness Compatible With Aftermarket HitchesFrom what I've been able to determine by looking at the online instructions for that Subaru Outback Hitch Panel, it appears that the OEM Subaru hitch sits up further on the vehicle, so the receiver tube exits through a hole in the bumper fascia, while the Curt # C67JR install so they sit a little lower, with the receiver tube sitting against the underside of the bumper fascia. Therefore the hitch panel wouldn't work with the aftermarket hitches mentioned above. The e65ZR has been discontinued...
view full answer... - Determining Correct Suspension Enhancement For 2013 Nissan Juke SVI may have another option but unfortunately there are no Timbren or Firestone suspension enhancement options confirmed to fit your 2013 Nissan Juke SV. The only option is to measure the spacing between the coils of your coil springs as depending on the amount of space you have there may be a Coil SumoSprings option. You will measure this distance with the vehicle on the ground, and you will want to make sure each side is within 1/4" of each other. I included a diagram of how to take this...

- Will SumoSprings Kit Affect Unloaded Ride Height of 2016 Subaru Outback WagonThe SumoSpring kit part # CSS-1125R will not affect the unloaded ride height of your 2016 Subaru Outback Wagon. It'll help reduce sag when you are towing but would not make the vehicle sit up any higher without a load on the vehicle.
view full answer... - Is Wheel Alignment Needed After Installing Coil SumoSprings Helper Springs on 2017 Subaru OutbackThe SumoSprings Custom Helper Springs # CSS-1125R referenced in your question are confirmed to fit your 2017 Subaru Outback Wagon. A wheel alignment is not needed as a result of installing this kit. The wedge-shaped springs will simply fit between the individual coils of your existing springs for additional support and cushion. I have attached the written installation instructions that you can also take a look at.
view full answer... - What Rear SumoSprings Coils do You Recommend for My 2017 Subaru Outback Wagon?I can definitely help! I am not sure which video you are referring to, but we do only carry rear SumoSprings Coils for your 2017 Subaru Outback Wagon. Those are the # CSS-1125R. These rear coils provide you with general suspension support that reduces body roll and helps level your Outback when towing a load. This is the only suspension enhancement we carry for your vehicle. There are no front coils or other suspension enhancements that we carry for the front axle. It is important to note...
view full answer... - Suspension Enhancement Recommendation for 2016 Subaru Outback Towing Camper TrailerYes, the SumoSprings part # CSS-1125R that you referenced are a confirmed fit for your 2016 Subaru Outback Wagon and would eliminate the sag you are experiencing when towing as that's exactly what they are designed to do.

- How To Eliminate Sag and Sway While Towing Boat Trailer With Subaru Outback WagonI do have a solution to not only prevent sway while towing your boat trailer with the 2018 Subaru Outback Wagon but also prevent sag. The Coil SumoSprings part # CSS-1125R are good for leveling out the vehicle and helps to reduce body roll but are not designed to help with the sway you have described. The 19MM Subaru Outback Rear Sway Bar Kit that you mentioned may eliminate rear sway at higher speeds but it is not going to eliminate the sag. I recommend a weight distribution system to...

- Helper Springs for Sagging 2008 Mitsubishi OutlanderI have never heard of anyone end up with a broken spring when using SumoSprings such as # CSS-1125R. If that did ever happen it was probably because those people thought that they could overload the vehicle because they were using the SumoSprings. Which is not true, the vehicle capacity remains the same, it is just better supported. With that said adding the SumoSprings will not grant you much, if any, additional height. They will help to keep the vehicle level if it is sagging. But there...
view full answer... - Will The SumoSprings Helper Springs Lift My 2008 Honda CR-V? The Coil SumoSprings Custom Helper Springs # CSS-1125R are not designed to lift your 2008 Honda CR-V. They are designed to assist in reducing your suspension from sagging with heavy loads. If your springs on your CR-V are worn and sagging from you may notice a slight increase in ride height but they are by no means a solution to lift your CR-V. We do not offer any lift kits currently for vehicles.

That said, we may have an option for you in the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension. In order to confirm we would need for you to measure the gap between the middle of the coils on your suspension (see photo below). The measurement will need to be taken with the vehicle as it sits, you do not need to raise it. You'll also want to be...

What you will need to do is measure the distance between the coils in the center of your rear coil springs. Depending on the distance between the coils there may be a Coil SumoSprings option such as the # CSS-1125R which will fit. This option installs in between your center coils and stiffens up the springs to keep your vehicle from sagging when towing a trailer....
view full answer... - Suspension Enhancement Recommendation for a 2010 4WD Toyota RAV4 I have rear suspension enhancement that I can recommend for your 2010 Toyota RAV4 but I checked with SuperSprings and they do not list their # CSS-1125R as a fit for the 4 wheel drive models. Instead you would want the Firestone kit part # F4174 which is a confirmed fit and would work well to provide you with rear suspension support. I attached an install video for this kit for you to check out as well.

I pulled these springs from our warehouse to make a video for you to give you an idea of what they look like. These springs are 6-1/8 inches in diameter. They have an overall height of 2-1/2 inches. The thickness is 3/4 inch and the height of the inner portion of the spring is 1-1/4 inch.

- Difference Between Coil SumoSprings for 2014 VW GolfThere is just a slight difference in size between the two parts; the Coil SumoSprings # CSS-1125R have a 1.25" inner wall height and are 2.5" tall and 6" in diameter. The Coil SumoSprings # CSS-1145R have a 1.45" inner wall and are 3" tall and 6.5" in diameter. Each of these springs are a fit for your 2014 VW Golf and though neither is stiffer than the other, they work by becoming stiffer depending on the load. Both products install the same on your Golf's coil springs and will give you...

When towing a trailer it is best to look into a weight distribution system. With a weight distribution system, it will relieve the pressure on the back axle and distributes that weight evenly.

view full answer... - Suspension Enhancement that Fits 2008 Mitsubishi Outlander with Strut In CoilThere isn't a way to install a coil rite air bag in a coil that has a strut that runs down the middle of it. You'd have to use a Timbren kit like the part # CSS-1125R.
view full answer... - Suspension Enhancement for a 2011 Honda CR-V EXWe are accurate, it is # CSS-1125R that is the correct fit for the 2011 Honda CR-V. I have even confirmed this with Super Springs. If the CR-V is bottoming out because it is coupled to a trailer then you will want to keep an eye on the tongue weight of the trailer. The CR-V is rated for 150 pounds tongue weight, check the owners manual to confirm, so a higher tongue weight could be one reason that is happening. The SumoSprings # CSS-1125R will firm up the suspension though and help to...
view full answer... - Recommended Suspension Enhancement for a 2011 Nissan PathfinderBoth the SumoSprings # CSS-1125R and Air Lift # AL60810 will help with the sag you are experiencing, however, I prefer the Air Lift # AL60810. This has to do with the adjustability of the air bags. These can be deflated to 5 psi, making them feel nearly, if not completely, non existent. This will keep the ride quality as close to stock as possible when not towing. They can then be ramped up to 35 psi, giving them very good support when you are towing. Though the SumoSprings # CSS-1125R...
view full answer... - Suspension Enhancement Recommendation for 2021 Kia Telluride With Suspension Sag When TowingHey Stephen, I would go with the SumoSprings kit part # CSS-1125R if you prefer a zero maintenance solution that once you install it you can basically never have to think about it again. The Air Lift air bag kit part # AL29PD would also work but it would be a better solution if you're the type of person who enjoys fine tuning things since you'd have to make sure the air pressure is correct when towing and not towing.
