Get the cushioning of SumoSprings for your coils. These wedge-shaped springs fit between the individual coils in each spring of your vehicle's front suspension for better load support and a more comfortable ride. Great for trucks with snowplows.
Features:
Specs:
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.
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.

Get the cushioning of SumoSprings for your coils. These wedge-shaped springs fit between the individual coils in each spring of your vehicle's front suspension for better load support and a more comfortable ride. Great for trucks with snowplows.These seem to make a big difference on the sagging front end of my '08 Ram 1500. Tip: Use LOTS of dish soap and install on a warm, sunny day. My first attempt at installation was on a cold day and the springs were inflexible and would NOT go on. They went on easily when warm.

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.
Helps with trailer squat tremendously - Installation was very difficult to expand strings wide enough
They don't seem to be the right ones for my silverado 1500 4x4. Too much play between spring even without lifting vehical?
These springs did not really change the unloaded ride quality. They also added about 1/2 of lift to the front of my truck. I wasn't expecting that, but it worked out for me. I installed a 2 inch front leveling kit about a year ago and I wished I went with a 2.5 leveling kit.
Product came as described, fast shipping, works great. Bought it to stiffen front end because of snowplow. Thanks
Easy to install, didn't affect ride, made carrying my plow much better.
Works Great

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
About all I can say for these is that they did raise the back of my Expedition EL about a 1/2". However, they didn't stay in place for even a year. As far as helping the ride of the truck with the travel trailer, I *think* it helped, but I really don't know if it is anything more than the placebo effect. I removed them before having Bilstein 5100 series shocks installed, with the spring collar set to raise .4", which did make a noticeable, positive difference in the way the truck handled when towing.

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.

I installed these on a 2020 Honda Passport (vehicle not listed in the fitment for this product). Installation was quick and easy. These worked great to help control the squat and reduced the bounciness when the trailer was loaded. After installation, I towed a single axle enclosed trailer (6'x14') with the contents of a single bedroom apartment from New Hampshire to Michigan and I am glad I made this choice. With them installed, I have noticed a very slight stiffness when not towing a trailer, but I intend to leave them on.

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
I have a 2014 Ford Expedition EL Limited that had tail squat while towing a 30 ft travel trailer even with a popular top of the line load leveling hitch set up. Air bags are a very expensive and difficult install for this model of large SUV. I followed the directions and with enough soap and a good jack to raise the car and extend the spring to its most extended position it was an easy install for each side. all I needed was about 1-2 inch to get level and it worked. Nice and level ride and a great feeling also not to blind everyone with my headlights while towing in the dark.
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?
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.

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

Didn’t fit my 2015 Ford Transit Connect cargo van. , my fault I didn’t return it I tossed box before trying to install part. Then I forgot about it while dealing with family emergency and having to move. Again maybe I looked up and ordered wrong part
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
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.
Review from a similar SumoSprings Coil in Vehicle Suspension
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.
