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.

Great for trucks with snowplows.These were difficult to install. Good thing I have strong hands. I do notice a firmer ride, which I need for hauling a truck camper. It seems to handle a little better, but slightly harsher when empty. Raised the front about 1/2”. Happy so far. Time will be needed for better evaluation.
These reduced nosedive hard braking when loaded significantly as well as leveling the front end when towing on my 4runner
Purchased these to take a little load of my strut assembly because of a heavy winch bumper and winch. Product works well....
Installed the SumoSprings Custom Helper Springs for suspension - Rear Axle on my Ram 1500. Easy install, if you follow their enclosed directions. It took longer to jack up the truck and secure it than the actual installation. Any negative comments that were written about the installation are most likely based on the ability NOT to read and follow the written directions. Took a drive after installation and immediately felt the difference in handling. Actually installed them to assist in the 30-foot travel trailer I am towing with a 1500 Ram. No doubt it is going to assist with the sway bars already on the trailer. In my opinion, it was a good investment for the price vs the results.
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.
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.
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.
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!
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.
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.
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.
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.
Have had these in for a year. Easy to install. I did have to trim some off to install, but super easy with a razor knife. Bought these to help level out my Pacifica and they’re awesome. Fully loaded and it still squats a bit but no where near as bad as it used to. No effect on daily driving. If you’re thinking about it, just do it.
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.
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.
Etrailer was very fast on delivery. The parts were just what I needed to stabalize my ProMaster van in crosswinds. I am very pleased with Etrailer
They seem to work as the back of my vehicle sag is not as noticeable with my trailer attached.
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!
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.
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
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.
I just received the springs today and haven't had a chance to see how they work because review is being sent out to quickly
Everything works great! I love products.
Here's a shot of the Sumo Springs installed on my 2005 Prius:
They definitely have helped with towing my Hike100 with my Toyota Highlander.
