1,500-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
Towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

1,500-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.I would have give it a 5star but the bolts are 1/4” I think it should be at least minimum of 3/8” or1/2” bolts to hold the sumo springs. I like them toed the camper handles very well. Wishi got these a long time ago worth getting. With out camper can tell that it’s there but rides ok. I wanted the same ride it not quite. I ask what the how high they are said 5” with bracket but it’s actually 6” with bracket see picture. I would recommend getting the sumo springs ssr-610-47.
Product was for a 2016 Toyota Tundra TRD Pro. I purchased these in preparation to haul a 25ft travel trailer. I was concerned that the installation of the Sumo Springs would affect the unloaded ride, so immediately after install I took the truck for a test drive and purposefully looked for and hit wholes along my drive. I am very pleased to report that the unloaded ride was not affected in the least. I have not picked up my travel trailer as of yet to report on how they did keeping the truck level with the trailer connected, but will provide an update once I have trailer and some additional miles on these. So far very pleased though delivered within the two day requirement I had.
First of all etrailer.com has shown again they have the best customer service. There's a reason I keep going back for my truck/trailer needs.
The 1500# SumoSprings I ordered (SSR-610-47) for my Frontier installed very easily. The total install took about 20 min. Having an impact gun definitely helped. Getting the U-bolt nuts off without one would be a bear. I opted for the 1500# to assist with squatting when I pull my 5K# camper. I am using an e2 WDH but its still squatting a bit too much for my taste, these should help with that. The ride without a load is stiff but not harsh. There's virtually no body roll like there was before even with new shocks. I'm looking forward to my first camping trip of the year and will update after that trip which will be about 250 miles round trip.

After a year Im still really liking this product. On my tow vehicle 2015 Nissan Frontier I ended up removing the very top section of the spring so that unloaded there was an inch gap between the spring and the frame. Before as stated the ride was stiff but not harsh because the springs made constant contact but werent compressed. That 1 inch airgap allowed for stock ride while unloaded but when a slight load when I stand on the bed for example it would make contact and provide all the benefits. For the Frontier Sumo could shorten it by one pillow and it would be perfect. Still highly suggest these for any mid size Frontier, Tacoma, Colorado, Ford Freaking Ranger or 12 ton truck you are towing with.
I had these replaced on my 2016 Tundra SR5 4WD CREWMAX that I tow a 28 ft travel trailer. I had my local mechanic install, hour later, done. Test drove it on country road, WOW. It drove like a sports car. The rear end took the bumps and dips no problem. The new stop basically takes up all the clearance between the frame and the axle. The response of the new urethane stop is progressive; no load, slight interaction and the more up/down action of the truck, the more the reaction. Tundra owners know that the rear leaf spring suspension is soft, car like. I am gearing up for a cross country trip w/trailer this October. I'll update this review later. I chose etrailer over the online big box store, same price, free shipping, delivered a few days later.

Worked great. California to Connecticut and back, all types of terrain and roads, truck n trailer behaved flawlessly. Even with my WDH and sway control adjusted properly, you will find yourself driving thru a dip in the road which could make your trucks rear end bottom out, which is why I opted for the Summo springs I dont need or want a 2500 series truckThis product works as it was designed and Im happy with it.
This was the answer to my rear sag when the trailer was attached. My wife never said a thing about the ride on our trip and I did not notice any difference. It probably took me 45 minutes to bolt the SumoSprings on the truck not bad at all. Good product.

Very satisfied. It is just what I needed.
Got the SumoSprings 3 days after placing the order. Installed them on my
2009 Toyota Tundra in about 45 minutes, saved about 2.5" to 2.75" of sag
with my trailer hooked up. Had 3/4" space between frame and spring
when operating without trailer.

I am sorry but I no longer own the Tundra, but I did purchase a Timbren Suspension Enhancement System from Etrailer just over a year for my Tundra replacement.
Worked well to take the front end bounce out while towing. Did very little to help with the rear squat on my 2010 Tundra towing 8k pounds. In the process of removing and installing airbags.

Thank you for your review. To me, it sounds like you need a weight distribution system. This system will distribute the tongue weight of your trailer. To learn more read below: https:www.etrailer.comfaq-weightdistribution.aspx

Just a little bit bouncy in the freeway when trailer is hooked. I believe it’s the concrete not being flat. Otherwise, it’s great! Squat is gone and driving the truck with the trailer is much much better. Thank you for the recommendation!
The springs do work fine on my 2013 tacoma , really help prevent sway when pulling my 15ft travel trailer . needed to cut some foam off the top to get some clearance for the shocks to work .

After a year or so the sumos are working fine under all of the trailers and loads I have been able to haul or pull
I installed the black ones on my Tacoma a little more than a year ago. For the most part I am happy with them. They work great when pulling the trailer, keeping everything level. When driving without a load the truck rides as comfortable as it did before installing the Solo Springs as long as the temperatures are above 20 degrees. When temperatures fall below 20 degrees things get noticeably rougher however.
These Sumo springs are the real deal! Installed them on my Nissan Frontier that I tow a trailer with and instead of the rear dropping 2 1/2 inches it now only drops less than an inch. Originally tried to buy another big brand name but it said it wasn't compatible with my truck. These Summo springs are second to none. Took about 45 minutes to install. Very happy. Highly reccomend.
Easy installation product performers just as it should.
100% stock 2017 Tundra SR 4WD V8. Bought these to provide a bit more stability when towing 27' 8600 GVW tag along camper usually running around 8000lb actual weight. Weight distributing hitch w/ sway control. Wasn't horrible before but wanted suspension stiffened up some. Easy to install if you have a torque wrench and the most basic of hand tools. Did exactly what I wanted it to do.

Still working great.
I called etrailer and asked which sumo spring I should purchase. I explained my trucks set and which trailer I was going to tow. I was told get the 1500 black sumo springs. Ok I believed that the person I spoke with was knowledgeable. WRONG! My tundra now rides like shit-super stiff rear suspension. I called back, could you please exchange for the 1000 blue springs? I am told no, but maybe I could sell the black sumo’s online? what a load of shit! etrailer wont back the advice they give or the product for a un-happy customer. I am out $250 for the springs and $100 for OEM u-bolts( tundra) I am now stuck driving my Tundra with horrible rear kick and stiff bounce. Goodby etrailer, never again.

I will have our customer service team reach out to you. The Sumo Springs do have a 30 day satisfaction guarantee.
The Sumo springs work well for keeping the back end of the truck level, However, the Sumo springs have made the ride stiffer which was unexpected from their descri[tion. Overall I am pleased with my purchase.
No pblm installing them on my '03 tundra. Hv used my truck for hvy loads constantly (alfalfa, firewood, lumber) and they are far superior than the air shocks i had previously. Would buy again.

Awesome! Still doing the job load after overload! Will not hesitate to add them to my next truck.
Easy to install simple bolt-on upgrade for better heavy load management for my 2008 Nissan Titan. After mounting these on my truck I noticed that my shocks were in need of replacement (i.e. 120,000 miles on the original shocks). The extra support of the Sumos made me more aware of the old age of my shocks.
I installed Sumo Springs on the front and rear of my 2019 sprinter van conversion for noticeable improvement of ride quality. Less sway and more control.
We have a Sprinter class C RV . Because the wheelbase is a bit narrow we experienced a lot of sideways roll even with a HD sway bar. The Sumo Spring Stablizer made a huge difference with the ride quality and stability. Highly recommend them as an inexpensive alternative to air bags.
This was the easiest thing to install i was done in ten minutes and that was only because i had the wrong size socket when i went under the truck and had get go get the other size. they clear very well. I will have my trailer on my truck soon and i know that this will work very well. I have tried many other things in the past i wish i had found this much sooner. this is on a 2016 toyota tundra and i pull a car trailer from time to time,
the trailer is a tilt trailer and is heavy duty so it has some tongue weight, This will solve the problem i have with the truck sagging in the rear
This product fit my 2010 Toyota Tacoma perfectly. The Sumo Springs were easy to install and I expect them to help support any heavy loads I carry by taking some of the load off of the leaf springs. They will also help keep my truck level regardless of the load I am carrying without making the ride any harsher.
Product was easy to install.Three months later I retighten them, they were just as tight as when I installed them. My camper rides and trails better.No dip in the middle.My trucked is rated for my camper but sometimes I have more weight in the back of the truck than I was expecting no trouble any more.
Easy to install and worked perfectly. The difference in truck bed sag was amazing after installing and hooking up the trailer. Handling and headlight up-tilt were corrected by installing this produce.
I have a 2009 Titan and these fit perfectly. Easy to install only about 30 minutes tops. Great addition for my truck to help handle bumpy roads and help reduce the bounce from my travel trailer. Crazy fast pandemic shipping. I would definitely recommend buying and buying from etrailer. Will absolutely be shopping with your company again.
These work perfect on my 2017 Tacoma, almost no sag when pulling my cargo trailer conversion. Ride is a little stiffer for everyday use.
Simply Amazing, i ordered these from my Nissan titan to help with the SAG of my travel trailer. Before I had these, my truck would sag 3 1/2 inches considering my trailer was completely loaded and had a 450 pound tongue weight. After I installed them, my truck only sags about a half an inch. The control and ride with these is just simply amazing. Insulation was a breeze, Took less than 45 minutes for both sides.

They are working great in my 12 tundra still would recommend them. I tow 8000lbs camper handles great at times I probably wished I got the next step up but might be to hard when not towing. Will see next time I need to get some for next truck. Wish they have measurements to know how high they are from the lighter ones to the heavier ones.
