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.
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.
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.
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.
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.
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 .
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.
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.
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.
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.
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.
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.
Great product, easy to install. I use them as back up for my air springs. Work great without air springs too. Thanks.
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.
I installed the helper springs and they have worked greatly, hauling my 4 wheeler around in the Nissan - thanks.
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.
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
Pain getting old u bolts off after being on there for ten years but sumo springs went in easy with new u bolts purchased separately. Looks like the sumo springs will work well.
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.
install was simple and they seem to do as expected would definitely recommend
Great product. I have Sumo Springs on the front and rear on both of my trucks. Does wonders for daily driving and handeling.
These work perfect on my 2017 Tacoma, almost no sag when pulling my cargo trailer conversion. Ride is a little stiffer for everyday use.
I have used these several times with great results, great product, great service
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.
They work well and were easy to install
