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.Shipping was fast and packaged well. The material looks and feels durable and easy to install but is a little loose on the springs, and not as snug as I thought. Although once I did a test drive around the neighborhood it tighten itself on the coil springs and hope it stays that way!
I used these to stiffen the suspension on a ‘21 Sedona. They work great and are easy to install.
2021 Highlander front with drive V6. Product is right on the money for description. My Bass boat is 3900lbs, definitely took a 1-1/4 out from the sag. Also, extremely less bounce. I would prefer to have air bags, though no one makes them for my year. This is a great alternative.
I have a 2015 Subaru Outback. When towing it went from a mushy rear end to a nice stiffness. Max tongue weight is 275# and with 220# on a recent trip (~2000# trailer weight) it only squatted the rear end about an inch (after rolling back and forth to let it settle).
Previously I was getting instability above 60mph especially when hitting the bumps at the ends of bridges. On my recent trip I was able to hit 80mph with the car feeling totally planted.
When totally empty you do get just the smallest hint of a 'truck like' ride but I typically carry some tools and other stuff all the time and that dampens it.
For install I found it helped to sort of feed the sumo into the coil as you kinda roll your hand over the part juming into the groove.
Installation was a bit more difficult than anticipated, however, for an 81-year-old guy, most everything is. The SumoSprings work just fine. I feel like they've reduced the sway and increased stability while hauling our Tab320 trailer with our Subaru Outback. Service from eTrailer was fast.
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.
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?
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.
Did not fit the 2022 Subaru Outback as advertised making these a total cash grab on etrailers part. Buyer Beware. Incorrect fitment guide means expensive mistake.
Install went fairly easy once I figured out the best spot to put the jack to lift the van. Really helped to have an oil filter wrench to get the old springs off the back. Took it out for a drive after an much better cornering and much less effect from wind and 18-wheelers. This was on a fairly windy day. No big difference in softness of the ride.
I was very excited about these for my 4x4 2015 Nissan Frontier. I am not completely displeased with them because they do make a mild difference over bumps, but they aren't worth over 100 bucks no way, the fact that I had to CUT THEM to fit due to them being too long made me feel like the company does not due their research when manufacturing them. It was so long that it lapped the beginning on it, so in order to have them installed as shown on the instructions I had to cut nearly 3 inches off... Which meant I had to comely install them, mark then uninstall, cut to fit, then install again. For an item to cost this much I expected better build quality.
Bang for buck it's not worth it, it's overpriced and I wouldn't recommend them for that cost.
I ordered these for my RAM Promaster 3500 because I had heard from fellow owners that they are a worthwhile addition, for increased stability on the road. The instructions are good, and they weren’t too hard to install myself. They are kind of expensive for a couple of rings of dense foam/plastic, but I guess they must be petty heavy duty. I look forward to my next trip to see how they perform.
The Sumo Springs installed easily and definitely hold up the back of the vehicle better and also firmed up the ride , now I want them for the front also. Great product!
They seem to work as the back of my vehicle sag is not as noticeable with my trailer attached.
Not easy to install. Took to a trailer shop for installation. Seem to stabilize my vehicle when towing, haven't towed after dark yet to see if oncoming traffic flash their lights at me.
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.
The installation was quick and easy. I did remove the tire to ease in the installation, it just made it easier for me. It took longer to stage the pictures for the review than install them. I took a measurement I think I gained a 1/4 to 1/2 inch in lift and doesn’t seem so floaty
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.
Took a chance and ordered rears for my 2021 AWD Pacifica even though the AWD model wasn't listed. After cutting a couple of inches off they fit perfectly! Coils are tight so you'll need to unbolt the bottom shock bolt to gain an extra inch of decompression. Once installed there's no difference in ride hight or ride with the van unloaded. Once loaded up it gives the extra support needed to prevent scraping my muffler pulling in and out of driveways. I know this mod voids the warranty, but it was a chance worth taking.
This was put on the rear of a '23 toyota highlander to help with it's lack of weight capability. It has helped and it didn't affect the ride quality.
I did not remove the front tire as I add more than enough room to slide them in. Quick and easy install. The front did not need to be trimmed.
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.
Everything works great! I love products.
Here's a shot of the Sumo Springs installed on my 2005 Prius:
They were very easy to install. Yes I use the instructions. They help keep from blinding people from my headlights when I have people in the rear seats. Great product.
