Most OEM coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. 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. Insert these helper springs in between the individual coil loops in your front coil springs to help defeat driver fatigue and to better support heavy front loads.


Coil SumoSpring installed between rungs of coil spring

Each doughnut-shaped spring has H-shaped channels at the top and bottom that fit to a rung of each coil in your front coil springs. Inside each round spring, a core of microcellular polyurethane foam adds cushioning between your coils. The cushioning absorbs shock, but also works progressively to better support front loads, and it keeps the front end more level. Unbumpify your ride with these SumoSprings for coil suspensions.

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.

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


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


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.

Did exactly what I needed it to do.
Luckly
I am supper strong to put this on.
Recommendation: Read the instructions, I did and took 1hr maybe. Also, use a dull wide screwdriver and slowly work around the coil.

Review from a similar SumoSprings Coil in Vehicle Suspension


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.



Comments
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


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 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


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.

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


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


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.

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.

OEM springs not strong enough.
After
installed feels a lot stiffer and raised the back 2". Material looks really good. Installation done in 40 min using a nut driver, a flat head screw driver and hand soap. I did have to take wheel off it just makes like easier.

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.

Review from a similar SumoSprings Coil in Vehicle Suspension


I have a 2008 Sienna that I pull a pop-up camper with. However, the Sienna sits really low in the back as is. With a trailer attached, the receiver would practically drag on the ground. After researching several different solutions, many of which being really expensive options (lift kits, etc.), I landed on the Coil SumoSprings. While advertised for performance, I read that they provide a bit of lift and prevent the springs from bottoming out. Installation was a bit tricky due to not owning a lift, but with the wheels and tires off (and an excessive amount of soapy water), They slid into place. The van sits almost 2 inches higher in the back. With the van fully loaded, a roof bag full on top, and the camper attached, the rear sits right about where it did without the springs when it was empty. These things are amazing! However, they were only about $60 when I purchased them last year. The price is much higher now, but still less than the other options I researched. I am super happy with the solution!

I drive a 2022 Ford Expedition Max. Installation was a breeze; it took longer to take off my wheels than to install these. Be sure to soak them in soapy water and they'll slide right on. The plan is to tow a 30' trailer. I have not towed yet but will update after some experience.

  • Recommended Ball Mount for a 2010 Toyota RAV4 With Factory Towing Package
    For your 2010 Toyota RAV4 Factory Hitch, you'll want about a 3 inch rise. You can confirm this by measuring from the ground to the top of the trailer hitch, and measuring from the ground to the bottom of the coupler. Then, subtract the higher number from the lower number. It does sound like you've gotten this about right though. If yours is a 1-1/4 inch hitch, I recommend the Draw-Tite Drawbar, part # 36063. This will give you a correct, 3 inch rise with a 3/4 inch ball hole diameter....

  • Front Trailer Hitch Receiver For Transporting a Dirt Bike With a 2004 Toyota Tacoma
    Yes, the Draw-Tite Front Mount Trailer Hitch Receiver # 65041 will be sufficient to carry your 280lb dirt bike with the 60lb carrier on your 2004 Toyota Tacoma. I do recommend using the Coil SumoSprings Custom Helper Springs # CSS-1125F to provide additional support to your front suspension. The front suspension on your Tacoma is not designed like the rear suspension that is there to carry additional weight. The SumoSprings will insert into your current coils and provide additional support...

  • Installation of SumoSprings Custom Helper Springs on 2012 Chevy Suburban
    The Coil SumoSprings Custom Helper Springs # CSS-1125F are a fit for your 2WD 2012 Chevy Suburban 1500's front axle and can install with or without the removal of the strut from your truck. They will adjust progressively so you'll get more stiffness from the springs the more weight you put on and they'd do a good job of helping support the extra weight from a brush guard and winch. I've added a link to a video review and installation of these springs for you to take a look at.

    The SuperCoils Custom Suspension Coils # SSC-30 fits the larger E-250 and E-350 vans but it isn't compatible with your 2010 Ford E-150. For your application I recommend the SumoSprings # SSF-106-47 as well as the Coil SumoSprings # CSS-1125F. These install in your OEM coil springs and also replace the bump stop on your van. They don't require any maintenance either so once they are installed you don't have to mess with them anymore. I have attached some review videos and written instructions...

The RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS54FR will not be impeded by the lift on your vehicle. This is also rated up to 3,000 pounds and will definitely help with sagging while towing. This can also be used in unison with the Roadmaster Rear Anti-Sway Bar # RM-1109-176.
