Get the cushioning power of SumoSprings for your coil springs and keep your ride comfortable. The wedge-shaped springs fit between the individual coils of your existing springs and help support heavy loads on your rear suspension.
Features:
Specs:
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.
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.

Get the cushioning power of SumoSprings for your coil springs and keep your ride comfortable. The wedge-shaped springs fit between the individual coils of your existing springs and help support heavy loads on your rear suspension.Pretty easy to install. During my first drive with them installed I heard a lot of thumping even over small bumps, but it seemed to work itself out on the second drive. I think it helps level out the slight sag in the rear of the car, and the front wheel drive which used to slip frequently when towing gets better traction. Be aware that for a 2005 Highlander, there are no holes or zip ties, and you can't get the Helpers to stay much higher than the lowest coil. I think them sliding down is what eliminated the thumping.
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.
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.
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.

There still seems to be less squat with my camping trailer attached. It is leveled out a bit.
These sumo springs have helped out my 2021 Ford Expedition Max in our frequent towing of our 29’ Imagine travel trailer. Before installation, the ride while towing was a little “squishy” due to the independent rear suspension on the vehicle, but now that these are on the rear coils, the ride while towing is much more planted and firm. I was worried that this would affect the ride quality when not towing, but the same soft comfortable ride is still there as prior to the installation.
Quick and easy way to firm up the rear end...while trailering.
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.

Weve towed a 30 travel trailer about 5k miles since the purchase. The tongue weight is 650-700 lbs. They allow a bit more squat compared with the Sumo Springs I put on my F150, but theyre definitely better than nothing, especially when paired with a weight distribution hitch. Unlike the ones I put on my F150, though, these dont seem to affect vehicle ride quality when the car is unloaded. Overall, Im happy with them and would buy them again.
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.
I put these on my 2016 Expedition EL Ecoboost after buying a travel trailer. The truck had plenty of power but as anyone could exped the IRS Sucks under heavy load and our first trip from east bay to Anehime made everyone sick from all the sway. I'm here to tell you this is the best $80 I have every spent upgrading any of my vehicles. I have since sold that trailer and now tow a heavier 28' TT and it pulls amazing. surprisingly it only affects the spring rate at fuller compression which is great for towing. Normal driving with no trailer feels exactly the same.
Installed on a Ford Expedition to counteract boat trailer sagging the tow vehicle. They have worked great......very happy with the product.
I installed on a 2014 Ford Expedition EL. I should have done this last year, it made it handle like it was new again both loaded down and when it was just me driving. It also retained the stock ride feeling with no harsh or roughness to speak of. For the folks that have a strut style rear suspension and put any kind if weight in their suv's and/or pull a tralier, this is a must. Also, no mentionable increase in ride height.
Did a great job helping with squat and not impacting unloaded ride quality. I have these installed in my 2019 Ford Expedition FX4 with a leveling kit so any sort of load really highlighted rear squat. I am pulling a 36' long 7000lb loaded travel trailer and I would consider these a must have. Install was pretty straight forward, take the weight off the rear tires, soap them up a little bit and they slide in with a little effort.
Installed on the rear of a 2018 Expedition, I pull a travel trailer thought these might help out. Very easy to install. Raised the vehicle about a 1/4” in the rear.
Took some effort and ~45 minutes to get these installed on my 2915 Expedition. Immediately noticed a different lace in ride quality and rear clearance height.
Install was pretty easy. I installed on A 2019 expedition. Decided to get this product when I had to replace my rear struts. I installed before installing stuts on the vehicle. Install would have been a little more difficult if struts were on the vehicle IMO. The ride in the rear is definitely stiffer more like a truck but that was expected since the sumos stiffen the ride unloaded. Excited to see how it handles pulling my new travel trailer.
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.
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

I am looking at this and am also puzzled as to why it did not fit, because it should have. Were you able to jack up the van so that the axle hung free? I can see trying to install it without following this step and it not working. I am wondering if this step was overlooked by mistake?
I used these to stiffen the suspension on a ‘21 Sedona. They are easy to install and work great.
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.
I tow a 32ft travel trailer with my 2006 Ford Expedition. I am not over my max tow limit but I am close to it. while towing even with my weight distribution hitch I felt the vehicle had too much front lift and too much rear squat for my liking. After looking around and not finding a lot of towing accessories for my vehicle I found the Sumo Coil Springs and decided to give them a try. Install was pretty easy and I did remove my wheels to give me more room to work. after installing the Sumo Springs I found that stock ride height had increased by about 1/2" to 3/4" in the rear and the ride quality had not been realy changed. After hooking up my travel trailer I now have an acceptable rear squat of about 1 1/2" and the front lift is only 1/2" and the trailer tows great.

Hello Patrick, I still thing the springs are great. They seem to still function today the same as they did a year ago. The only thing I had to do to the was install better and more zip ties on the springs than what came with them in the box, to better hold them in their proper position.Thanks for the follow up.
We put these on our 2014 Highlander a year ago and it makes hauling our airstream Basecamp 16 so much better. We were looking at getting a wieght distribution hitche but they were so heavy they would’ve put our tongue weight over spec. this has been a perfect solution
Installation was a little challenging, but once I figured out the trick to get the spring installed the installation became easier. The springs off set 4 passengers and two bicycles that we also added with a hitch to our Honda Fit.

The Sumo Springs were a little challenging to install on my Honda fit but was able to get them installed. The Sumo Springs were installed in conjunction with the Draw-tite hitch and Swagman bike rack to level out rear of car with to ebikes installed. The sumo springs handles the roll and pitch during lane changes and turns.
Not as easy to install as noted in the documentation; Otherwise, they are performing as advertised. I have not lost the ride quality yet I noticed a difference pulling our fully loaded trailer with the Jeep or the bikes. Much better handling. I would have preferred air bags, but these are doing the job.

Excellent! Working as advertised all this time. Thx you.
Here's my story and I'm sticking to it. First off, the Toyota Highlander is built on a car suspension, not a truck suspension, so a lot of the towing accessories you can get for trucks do not apply. I have a boat and trailer that weight approximately 2200 lbs, and the tongue weight although not too big causes the rear end of my highlander to sink a bit more than I'd like, and you could feel the car suspension bounce a little bit too much when the trailer bounced. I purchased this product and had my mechanic install it. It did just what I expected, and the ride is much better now. Plus when the trailer is not attached, the little bit of rise makes the vehicle look meaner to the point where I might just paint sharks teeth on the front bumpers (okay maybe not, but I thought about it).
I installed the SumoSprings on a 2009 Honda Ridgeline to be able to tow a Winnebago 2106 trailer. With the springs installed I have had no problems towing. The Trar as I call it, part Truck and part Car does not dip / sag with the trailer connected. Practiced emergency braking and did not have any problems. I would recommend this product. Did not take any pictures with it connected, sorry. They were pretty easy to install, the soap and water helped a lot.

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