Insert these helper springs in between the individual coil loops in either your front or rear coil springs to defeat driver fatigue and add better support for heavy loads. Most factory front coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. 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 clearing snow or driving to a campsite.


Coil SumoSpring installed between rungs of coil spring

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 front or 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.

Installed on 2014 Ford Expedition limited and very happy with this product, improved the ride when towing and not towing.
Installation was relatively easy thanks to the people from etrailer that helped me choose the right size for my vehicle.
Thanks everyone at etrailer for helping me with this project.

They seemed to help with towing our popup camper on our 2012 Highlander. The popup is 2,800 pounds unladen weight. Installation was very easy. I didn’t have to remove the tires. Just jacked up the rear of the vehicle to gain a little more access and they slide right into the coils. I feel that the price was pretty steep considering all the more that they are and they couldn’t even throw in the zip ties to boot. Claimed to be made in USA, but I can only hope that they were again considering the price. All in all I’m pleased with them.

Easy to Install. I did not notice a difference in the unloaded driving characteristics of my car.

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.


Comments
Excellent product. Holding up great. When towing my camper, the squat is less the 1. Much better then before when 3 was the norm.

Easy to install on 2020 Mercedes Metris Cargo Van if you remove tire, clean spring and use soapy water to lubricate coil. Reduced "squat" about 3/4" for ~325 Lb. trailer tongue weight without weight distribution hitch.

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.

Review from a similar SumoSprings Coil in Vehicle Suspension


The Sumo Springs Custom Helper Springs I purchased and installed on my 2022 Winnebago Solis 59PX have made all the difference in the way the vehicle handles. I purchased both sets of helper springs for the front and rear. They have made a huge difference. I believe they are worth the price of the products.

Review from a similar SumoSprings Coil in Vehicle Suspension


Pretty easy install on a Winnebago Solis, built on the Ram Promaster 3500 chassis, took about an hour to install on all 4 wheels. I only parked on a level surface and used the factory jack, didn’t even lift the van off the ground all the way but enough for clearance to install, no tire removal done. I gained about an inch of clearance which is nice for my onboard generator and hoping for a better ride on windy days. The pictures are before and after of (in order) front, rear, size difference of Sumo vs. oem and the generator.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Review from a similar SumoSprings Coil in Vehicle Suspension


Ok installed outside january 27th. Temp 10 degree windchill -5. I used canola oil since it stays slippery when cold. I recommend taking off the tires. Also wirebrush the coil spring to get rust and debris off. Coat coil spring in canola oil. Also 1997 crv rear will require about 3/4"-1" off of the helper spring before hand. The driver side took 15-20 mins the passenger less than 5. My car rear was sagging it sits level or slightly above level now in the rear. Mileage of vehicle is 73k shocks struts and springs are original. Curt class 3 hitch is also installed on vehicle. I am curious to see how it does while pulling a 5x8 trailer. Overall seems good only time will tell. Wondering how installing two on a side would do?


Comments
So far so good it eliminates sag while towing or having heavier objects in the vehicle.

Review from a similar SumoSprings Coil in Vehicle Suspension


I could not place the SumoSprings in the middle of the coil springs to start installation. Rather I had to start lower on the coil springs, where the spacing is wider, and then slide the SumoSprings up to the middle.
I used a screwdriver run into the holes for that purpose to help slide the SumoSprings to the middle of the coil springs. Otherwise, the installation went well. There seems to be less squat in the rear of my '04 Highlander when my camping trailer is attached.


Comments
There still seems to be less squat with my camping trailer attached. It is leveled out a bit.

Recommendation: Read the instructions, I did and took 1hr maybe. Also, use a dull wide screwdriver and slowly work around the coil.

Easy install. Took less than 20 minutes including the time to drive to a neighbor to borrow a floor jack and stands.

Definitely use soapy water liberally to help slip it into place.


Comments
This was an excellent buy. It helped with rear squat and stabilized the rear end of the vehicle to a surprising degree. Much less bouncy and reduced porpoising.

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.

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

Review from a similar SumoSprings Coil in Vehicle Suspension


I received the Sumo Springs Coil Helper yesterday and was able to install it in less than an hour on my 2007 Odyssey. May be even quicker if I had a better jack(i had to lift one side at a time). My van now has raised significantly. With a three Mountain bike rack, camping gear loaded with the roof box, the van's rear end was too sagged. I gained close to two inches after installation. I do notice a difference in the cushioning, but that is very marginal. Overall, I am very happy about this product and would recommend if your car's rear end needs a lift/ support. Installation was very simple with the hand soap applied. I will do a follow-up review after few weeks when I put a few hundred miles for my summer trips.

Review from a similar SumoSprings Coil in Vehicle Suspension


2009 GMC Sierra CC 2WD
It does take some
time and sweat equity to install. I think some may have a harder time if both tires are not off the ground at once. Lifting only one side, the front sway bar may transfer some of that compression to the tire in the air possibly causing that spring to have less room between coils.

They work as advertised however may need not be for everyone. I like how I can take corners at higher speed as if it is on rails (I also have the rear sumos). No nosedive during emergency stops. Not too intrusive when driving on smooth pavement but over rough or broken road can be tiresome over time. I guess they took a little more "spring" out then I was hoping for.

I am considering taking them out and installing a larger front sway bar.

Review from a similar SumoSprings Coil in Vehicle Suspension


before installing the SumoSprings in the rear of my 2015 Honda CR-V the rear ride height would be level and when I loaded my powerchair
(electric wheelchair) on the rear lift of my car it would sag 3"and be vry twitchy in the steering, it did not feel safe at all, after installing the SumoSprings it would ride level and be much more stable in the steering, when I unload my chair my car is at the proper ride height it did not jack up the rear end at all. I'm very pleased with the SumoSprings and would recommend them to anyone.

Review from a similar SumoSprings Coil in Vehicle Suspension


I was very pleased with the Sumo Springs for my 2015 Toyota Highlander Limited rear springs. Was a little worried if they would fit and if I could install them myself. Turned out to be fairly easy after watching a few YouTube videos. It's important to get the springs fully released by getting the tires off the ground an inch or so. Be sure to use safety jacks so you don't lose a hand or fingers. I had to jack up each side separately. Follow the directions by cleaning and spraying the car springs and spray Sumo springs too with soapy water. Was a little tough getting them started, but once in place would spin easily to get into position between the 2nd and 3rd spring and also to rotate to install all the zip ties. I loaded my hitch with 300# on a cargo carrier. Without the sumo springs dropped 1 1/2". With Sumo springs only 1/2". The 300# simulated the tongue weight of a camping trailer I am renting next week. 1" difference may not seem like a lot, but I was pretty pleased that such a easy, low cost fix that will allow me to tow up to the 5000# capacity rating of my SUV. I didn't notice any difference in handling when driving without any weight. My cargo carrier also has a 500# capacity so I'm good for traveling towing a camper or with my cargo carrier. As always, eTrailer was great about fast shipping. Ordered on Tuesday and arrived on Wednesday. eTrailer is my go to place for anything auto related.

Its still working great. Glad I installed the Sumo springs.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Raised rear of my 2021 Outback 1 1/4” and it also raised my front 1/4”.
Little stiffer in the rear and less dropping of rear during Acceleration.
People are always flashing me the high beams before, these should reduce the amount of high beams I get.
Would have given it a 5 Star But it would be nicer not to have to cut the excess off.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Review from a similar SumoSprings Coil in Vehicle Suspension


Just returned from our first trip after installation of coil spring suspension- front axle and SumoSpring Solo Custom Helper Springs-rear axle. A significant difference is noted in ride as there is less bounce and sway. Cornering is more sure and flattened this noted on many curved mountain and rural roads traveled in Western and Central PA. Turnpike travel was smoother as road tar strips were not as notable given a stiffer ride.

Review from a similar SumoSprings Coil in Vehicle Suspension


Initial reaction is positive - I installed front and rear sumo helper springs yesterday (5-23-19) and did a test drive around the block. The side to side pitching of our Transit Class B+ motorhome was greatly reduced. I still need to test on highway. I did not install the optional spacers that increase the ride height and reaction time of the rear sumo springs. The spacers will be added later if needed.

  • Comparison Between SuperSprings # CSS-1145 And # CSS-1145R
    Part # CSS-1145 and part # CSS-1145R are identical helper springs. They are designed to fit the rear only for your 2013 Dodge Durango. Originally these were designed for both the front and back and the R indicated they were to be used on the rear only. These are inserted between the coils of each coil spring on your Durango and help to reduce body roll and help keep your Durango level. As more weight is added the stiffer they become.

  • Ability of Coil Sumo Springs # CSS-1145R to Raise Ride Height of 2012 Jeep Grand Cherokee
    The Coil SumoSprings you mentioned, part # CSS-1145R will not change the ride height of your Grand Cherokee. They are meant to smooth the ride and help eliminate some sag caused by carrying heavy loads in the cargo area. In other words, the SumoSprings will not lift the vehicle, but will help resist against sag when the vehicle is under load. Various aftermarket lift kits are available in different heights. I would recommend doing a Google search on a lift kit for 2012 Grand Cherokee.
