Rear Suspension Support

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.


Installed spring when it is not compressed

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.


Installed spring when it is compressed

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.


Durable, Custom-Fit Springs

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.

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.


Comments
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.

Nissan Frontier

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.


Comments
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.

Toyota Tacoma

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.

2016 ToyotaTundra

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.




by:

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.




by:

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 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.


Comments
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.

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.

2017 ToyotaTundra

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.

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.


Comments
Very satisfied. It is just what I needed.

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

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.

Great product, easy to install. I use them as back up for my air springs. Work great without air springs too. Thanks.




by:
2010 Toyota Tacoma

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.

Nissan Frontier

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.




by:
2016 ToyotaTundra

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




by:

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.

Great product. I have Sumo Springs on the front and rear on both of my trucks. Does wonders for daily driving and handeling.

2019 Nissan Titan

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

    If you are still experiencing sag after installing the helper leaf springs, I recommend to use the heavy duty SumoSprings Solo Custom Helper Springs part # SSR-610-47 1,500 lb capacity to help eliminate the sag. The great thing about the Sumo Springs is their porous construction allows for progressive load control which means the intensity of their compression matches the weight of the load.

  • Recommended Suspension Enhancement for 2015 Toyota Tundra Towing a Camper
    I recommend using the SumoSprings Custom Solo Helper Springs # SSR-610-47 because they're designed to help reduce sag while towing, reduce body roll and they don't affect your ride quality when you're not towing. These springs are designed to be progressively load bearing, so they'll compress more as greater weights are applied to them so they're ideal for people who bumper tow and carry loads in their truck bed.

  • Fit of SuperSprings SSR-610-47 Solo Helper Springs on 2014 Toyota Tundra w/ 1 Inch Lift
    According to my SuperSprings representative, the 1 inch increase in ride height provided by the block won't do much to change the effectiveness of the # SSR-610-47 Solo Custom Helper Springs. As you can see in the photo I've provided, The spring sits about an inch below the frame member on a Tundra with a stock ride height. Your 1 inch lift will mean that the truck's suspension will need to compress a bit more before the Solo Springs come into effect.

  • Will SumoSpring SSR-610-47 Have a Gap Between Vehicle Frame When Unloaded
    They are 6 inches tall. You do want a bit of distance between the SumoSpring and where it would contact the vehicle. This allows the ride quality to not be affected when the vehicle is unloaded. You don't want the SumoSpring # SSR-610-47 making contact all the time as that will give you a very bumpy ride quality.

    The SumoSprings part # SSR-610-47 would be exactly what you are looking for.

  • Timbren or SumoSprings Recommendation for 2018 Toyota Tundra
    I prefer the SumoSprings kits over the Timbrens for your 2018 Toyota Tundra. The reason I do is because the Timbrens have a reputation as being harsher when the truck is unloaded. So for your truck I would recommend the # SSR-610-47 which will give you the suspension support you want but without making your ride quality harsh when the truck isn't loaded.

  • SuperSprings Rear Axle Helper Springs for 2016 Toyota Tundra 4WD Towing 7800-lb Car Hauler
    Your Big Tex trailer with a 7800-lb loaded GVWR probably has tongue weight (TW) in the range of 900- to 1100-lbs so the SuperSprings rear-axle kit # SSR-610-47 you referenced is what I recommend. This 1500-lb-rated jounce spring kit will lend enough support to the rear suspension on the Tundra without being too stiff. Since the exact position of the Land Cruiser on the trailer can affect your tongue weight having the little bit of extra capacity is a good idea.

  • Suspension Enhancement Recommendation for a 2010 Toyota Tundra
    The # SSR-610-40 is the light duty SumoSpring available for your 2010 Toyota Tundra. These will have 1,000 lbs of support whereas the # SSR-610-47 would be considered the heavy duty version and would add 1,500 lbs of support. For you I would go with the heavy duty version. You should not that suspension enhancement does not allow you to carry loads heavier than what the current vehicle capacity is. It just provides more support to allow you to carry your capacity as safely as possible.

I prefer this one to the 1000-lbs version # SSR-610-40 in case you may be carrying any additional cargo or you use your truck for carrying loads when not towing.

  • Differences Between SumoSprings Kits for 2013 Toyota Tundra
    The difference between the two SumoSprings Solos kits for your 2013 Toyota Tundra is the weight capacity for either. The part # SSR-610-47 provides 1,500 lbs of suspension support and the # SSR-610-54 has 2,800 lbs of capacity. Since you said you wanted a smoother ride the lower capacity # SSR-610-47 is the way to go. Heavier rated springs will make the ride bouncier or rougher.
