Insert these helper springs in between the individual coil loops in either your front or rear coil springs to defeat driver fatigue and add better support for heavy loads. Most factory front coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. 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 clearing snow or driving to a campsite.


Coil SumoSpring installed between rungs of coil spring

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 front or 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.

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.

My experience with these are still good. I did notice that one side had rolled off the coil despite having the zipties still in place, but they still work as well as I could have expected. I still experience some sag while towing a trailer, but it is not as bad as if I did not have these installed. This vehicle seems to be very sensitive to tongue weight even when the trailer is empty



by:


OEM springs not strong enough.
After
installed feels a lot stiffer and raised the back 2". Material looks really good. Installation done in 40 min using a nut driver, a flat head screw driver and hand soap. I did have to take wheel off it just makes like easier.



by:

2005 Honda Cr-V, they went on pretty easy, it was a tight fit but no trimming required. I jacked the car up on some stands, had both sides installed and zip tied in 45 minutes..



by:

Sumo springs installed without removing tires, just used a 2 ton floor jack to lift the rear tire off the ground to put the lift spring in a negative relaxed position. Then followed instructions and cleaned springs with dish soap and water, also used solution on sumo lift coil. Coil snaked between lift springs without any problems. Placed Ty’s per instructions using a needle nose pliers to pull tyes securely in place and cut off any excess tye. Sumo are working great .!! If you haul a trailer get these springs lifts the really do work according to advertisers info.



by:

Delivered on time. Installed on 2015 Kia Sorento. Super easy. Took the tires off the rear to install. Left the tires on for fronts. Having a much, much better ride now. Went from a sloppy rolling mess to a much more controlled experience. Highly recommend.



by:

Always great service with you guys. Suggestion would be the ability to add a PO to orders. We deal with the VA a lot and we use the Veterans last name for ordering.



by:

Great product, fast delivery.



by:

Great product these coil are simple and quick

by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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!



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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!



by:

They seem to work as the back of my vehicle sag is not as noticeable with my trailer attached.



by:

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.



by:

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



by:

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.

  • Correct Number of Coil SumoSprings Custom Helper Springs Needed for 2020 Toyota Highlander
    The Coil SumoSprings Custom Helper Springs part # CSS-1145 for AWD or part # CSS-1125 for FWD will use one spacer per coil spring, you cannot use two per side nor would you want to as the ride would be too stiff but there is not enough room anyhow. These will be great for towing or hauling heavy load and they are currently the only option we have to help with rear end sag/squat.

  • Suspension Enhancement Recommendation for a 2006 Honda Pilot
    For your 2006 Honda Pilot I have a suspension enhancement solution that I can recommend, but the part # CSS-1125 would not be it since it is not confirmed as a fit. Instead you would want the Timbren system part # THROD2. This does not fit in the coils at all so you would not need to compare it's dimensions to what you already have.

    I may have an option for you, but at this time there is not a rear suspension enhancement option confirmed to fit your 2016 Audi Q5. If you can measure the distance between the middle coils on your rear coil springs, there may be a Coil SumoSprings option that will fit. The Coil SumoSprings like the # CSS-1125 install in the middle of your coil springs and support your factory suspension by up to 30%, and would help to prevent rear suspension sag when towing a trailer.

  • Suspension Enhancement to Prevent Sagging While Towing With 2021 Toyota Highlander XLE
    Yes, the Coil SumoSprings Custom Helper Springs # CSS-1145 will help prevent the sag you are experiencing. These will provide additional support and use progressive load control so they get stiffer as you add more weight. The # CSS-1145 will work for the AWD model. If you have the FWD model then you can use the # CSS-1125 instead. Proper installation of the SumoSprings will not damage your vehicle or void the warranty.

  • What is the Difference between the SuperSprings Coil Insert # CSS-1125 and # CSS-1125R
    The SuperSprings Coil Spring Inserts, # CSS-1125 and # CSS-1125R, are the same exact part and both will fit your 2011 Honda CR-V EX-L. The actual part number from SuperSprings is CSS-1125, but we put an R or an F on the end of the part numbers for these products to indicate if it is used for Rear coils springs or Front coil springs on a particular vehicle. For example, on your CR-V, these springs are used on the rear coil springs, so we put an R at the end of the part number. These springs...

  • Coil SumoSprings Helping Sag On 2019 Subaru Outback Wagon
    The SumoSprings # CSS-1125 will help your front and back suspension from sagging as much on your 2019 Subaru Outback Wagon. Putting these on the rear axle will help your suspension from compressing as much which in turn will help your front end from raising up so bad.

  • Will the SuperSprings Coil SumoSprings Fit a 2015 Volkswagen Passat TDI
    The SuperSprings Coil SumoSprings, # CSS-1125, will fit your 2015 VW Passat TDI. You are correct that the Firestone airbag kit, # F4176, will not fit the TDI models, but based on the coil spring dimensions you provided in the attached diagram, these SumoSprings will work for you and help level the rear end of your Passat with the weight of the bike rack and bikes.
