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.

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.
Thomas - 09/20/2021Did 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.
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.
Michael T - 08/15/2015I 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.
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
Brooke M - 12/15/2022I 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.
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
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.
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.
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.
They leveled out the Expedition with the 1985 Avion on the back of the vehicle for towing
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.
Joe O - 01/27/2022I 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.
Products were as described and the install video made it a cinch!
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.
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.
Excellent product, 2019 Expedition tows with much more stability.
Install was bad and they helped raise the back of my van. I would have given them 5 stars if they raised the back of my van even higher.
Worked great and didn’t affect the ride quality.
These were a big help on an overloaded minivan. I carry a heavy hitch mounted bike rack and 4 mountain bikes, and then load up for a normal week's vacation of camping. The Helpers worked like magic, and kept the back end from bottoming out and helped give a little extra clearance when it comes time for backing out of descending driveways and speed bumps. They installed easy, and greatly improved the ride, and performance of the van. Well worth the time and money spent. Go for it, especially if your packing too much fun into a family minivan.
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.
A. f - 09/01/2019I have had these for a year now. They were easy to install. I pull a 6500lbs. travel trailer with my Ford Expedition. And a 3500lbs. enclosed trailer. After install I have noticed less rear sagging in rear. And I have not noticed a big difference in ride Quality when not towing.
I installed the SumoSprings on my 2017 Expedition. I have the heavy duty towing package, but the weight of my travel trailer is close to the limits for the Expedition. I bought these to raise the rear of the vehicle under load and to reduce bounce on the roadway. Installation took about an hour and following the directions they went in fine. Note: Use soap and water to clean springs as they say but also make sure you have the spring wet with soap and water to ease the installation. Taking the tires off, definitely helps in installation. Taking measurements before and after showed that I gained 1.5 inches height on the rear of the vehicle under load. I look forward to taking the trailer on the road to see if there is an improvement in handling. I expect an improvement since the front is now lower under load.
I have a 2015 Toyota Highlander with a hitch mounted cargo box and am moving and vacationing at the same time. Therefore have a lot of weight in the vehicle, though not even close to the max vehicle weight or axel weight. However the vehicle significantly sags in the rear. I'm glad I found theses helper springs as they did make a significant difference in reducing the sag (probably by an inch) and therefore handling of the vehicle (steering, body roll, etc.). I was actually very surprised at the difference it made in the handling. To note, I drove with the load without the helper springs from VA To SCand then with the helper springs from SC to OH before reviewing. They were also very easy to install. I only jacked up the rear end and slipped them on (without soapy water) in less than 15 mins with zip ties. The results from the product were well worth the purchase and will be recommending to friends and family.
In regards to Etrailer, they ended up being out of stock after I purchased the item and they quickly called to let me know and when they'd become available (only a couple days for them to get the product, no big deal). Always great customer service.
