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.


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 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.

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.

2013 Subaru Outback Wagon

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.



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

Coil 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.

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.


Comments
Continue to be pleased with the SumoSprings on our 2005 Subaru Outback. The alternative was to spend $800 for new heavy duty rear struts. They work well to prevent bottoming out when towing a camper and dont seem to effect the overall ride quality when not towing a trailer.

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.




by:
2011 Subaru Outback Wagon

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




by:

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.

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.




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.

  • Will Rear Suspension Enhancement Springs Increase the Tongue Weight Capacity of a Vehicle
    Rear suspension enhancement will not increase the tongue weight capacity of a vehicle. They will only reduce the amount of sag in the rear suspension. I looked up the owners manual for your 2008 MKX and it looks like the maximum tongue weight capacity for your vehicle 350 lbs no matter what additional components are used. My recommendation would be to reduce the tongue weight on the trailer. If your travel trailer has anything mounted on the tongue such as propane tanks or storage bins,...

    The # CSS-1094R Coil SumoSprings helper spring would indeed help reduce some of the minor sag caused by the tongue weight of a trailer being applied to the rear suspension of your Touareg. The product mounts in between the coils of your existing rear springs to provide additional support and dampening. They will also help reduce body roll experienced in turns.

  • Will Installing The SumoSprings CSS-1094R On A 2020 Subaru Ascent Lift The Rear When Unloaded?
    As the Coil SumoSprings # CSS-1094R will fit in between the slats of the coil spring on your 2020 Subaru Ascent, it will not lift the rear up at all. However, they will definitely help if the back of your vehicle is sagging as they will supplement your factory springs and give them a little support when needed.

    The SuperSprings Coil SumoSprings would be an excellent addition to your 2010 Subaru Outback Wagon to help reduce sag when you are carrying your motorcycle.

    Since your 2014 Subaru Outback is not rated for use with a weight distribution system the best option would be a suspension enhancement kit that fits your vehicle like the Coil SumoSprings part # CSS-1094R. But no option will give your vehicle/hitch a higher towing capacity to tow beyond the capacities of your vehicle.

  • SumoSprings Suspension Enhancement Recommendation for a 2009 Subaru Outback Wagon
    Yes, there are SumoSprings available that are confirmed to fit your 2009 Subaru Outback Wagon. If you have the H6 engine you would want the part # CSS-1069R. If you do not have the H6 engine you would want the part # CSS-1094R. Other customers who have bought these two part numbers have left reviews saying the install was pretty easy and that removing the wheels helped. Soapy water can also be used if the spring is being stubborn.

  • Suspension Enhancement Recommendation For 2004 Chevrolet Tahoe 4x4
    Personally, since you are in the market for a smoother ride, I recommend the Coil Sumo Spring Custom Helper # CSS-1094R, which, as an added bonus will help support heavy loads on your rear suspension. The Coil Sumo Spring, unlike the AirLift # AL60769 that you referenced, will not have to be adjusted or monitored. I have attached the installation directions, but, basically, they simply fit within your existing coil springs and secures with zip ties.
