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.

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.




by:

Helps when under heavy load and reduces “bottoming” out effects on rough terrain. Using this for towing a travel trailer approximately 8000 lbs. with a 2008 Ford Expedition.




by:

Just finished installing these on my 2014 Ford Expedition EL Limited. Very easy to install. Never removed the wheel to install. Jacked the vehicle up one side at a time and did the install. Haven't hooked to my 30ft camper yet to see how they work. Will update after my trip in July.




by:

Installed over a year ago on a 2020 Ford Expedition. I pull a 30’ travel trailer and the sumo springs made a big difference. Well worth the money, easy installation.




by:

Put these on my 2017 Ford Expedition EL equipped with the factory installed towing package. I tow a 2014 Winnebago 30 RE. I had used these on my previous Expedition. The tongue weight of the trailer is such that I got about 1 1/2" of "squat" when hitched (and with the weight distribution hitch correctly set). The Sumo Springs reduced the sag by about 1".
A bonus if you will is that these have no effect on ride when the trailer is not hitched to the vehicle.
These work well and are a great alternative to air shocks. They can be a bit tricky to install but with some patience and elbow grease you can get em on.




by:

I installed these on our 2020 Ford Expedition this past spring. Went on super easy using a little dish soap, much easier than I had heard from other reviews/videos. Works great to prevent squat while towing our travel trailer with a 900 lb tongue weight (scale weighed). I do notice a slight increase in stiffness/jitter from the rear when not towing and vehicle is lightly loaded, but nothing that makes me want to remove them.




by:

Only took about 20 minutes .it was a perfect fit for my 2017 expedition. My 20ft toy hauler rides perfect with this set up .




by:

I didn’t notice a change in ride. It decreased the squat between loaded and unloaded by 1/4 inch. It also raised the back by 1/4 inch. 2019 Expedition Max.




by:

Got em in! Not the easiest install, but they seem to stiffen up the ride. I’ll update after the next trailer trip...




by:

I installed these on the rear of my 2017 Ford Expedition EL, hoping it would help with the ride quality and handling while towing my 6,500lb travel trailer. The box did not come with instructions, but I downloaded them from etrailer's site. Installation was fairly easy, although I did have to take the wheels off. After my first trip with the trailer (400) miles, I didn't really notice any improvement with the handling, but hopefully they are helping take some of the stress off the rear springs. These are fairly expensive for something that has no noticeable benefit, so I don't think I could recommend them.




by:

eTrailer delivered once again! Great service, support, and the product was exactly as advertised. Installation was easy with clear instructions. The product seems of great quality. I have yet to try the car with the trailer connected, but from the looks of the installation it seems that the results will be as good as the experience thus far. I recommend eTrailer.com.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.




by:

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.

The Sumo Springs you actually need are # CSS-1168R for your Highlander. These will help to take out the sagging and ease some stress on the suspension.

    Suspension enhancement is great for vehicles that are carrying a heavy load in the cargo area of the vehicle. But if the sag is from towing a trailer a much better solution is a weight distribution system.

  • Will Coil SumoSprings Fit a 2012 Kia Sorento EX All Wheel Drive
    The Coil SumoSprings # CSS-1168R are designed to fit a gap between coils in a spring of 1-3/4 inches. For your 2012 Kia Sorento they could potentially be used if the space between the coils of the springs is 1-3/4 inches. They are listed as a fit for the 2012 Hyundai Santa Fe which is very similar to the Sorento (many of the same aftermarket parts fit both vehicles). But there was a chassis change in 2012 so the SumoSprings may not work unless that gap is 1-3/4 inches.
