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.

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. 491949

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 274638

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. 561547


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.

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. 467194

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. 323053

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. 735105

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. 635969

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. 596474

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. 555739

  • 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.

  • Solution for 2017 Toyota Tacoma that Has Suspension Sag When Towing
    For your 2017 Toyota Tacoma the correct SumoSpring kit is the part # SSR-612-47 and not the kit you mentioned as that is for the older models. This will reduce the sag but what you might be better off with is a weight distribution system since that reduces the sag too but in doing so helps improve braking and handling as it distributes some of the tongue weight up to the front axle. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of...

    The compatibility of the SumoSprings Solo Custom Helper Springs part # SSR-610-47 with a lifted 2019 Toyota Tundra TRD will come down to the type of lift. If the distance between the jounce spring and contact point has changed then these would not be a good option.

  • 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.

  • 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.

  • 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.

    Weight distribution (WD) systems actually take on the weight of any cargo behind the rear axle of the tow vehicle (your 2010 Toyota Tundra) as well as the tongue weight (TW) of the loaded trailer. This is why you are finding that your WD system isn't performing as well when you load down the bed of your pickup. For example, the Equal-i-zer # EQ37100ET has a TW range of 600 lbs - 1,000 lbs.

The # SSR-610-47 that you are referring to is a heavier-duty application with a 1500 lb capacity at 50% compression, and I recommend these if you will be doing a lot of hauling since they have a much stronger capacity, but for occasional hauling the 1000 lbs springs are more ideal and won't give as bumpy a ride when unloaded.

    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.

Your tongue weight of 460-lbs is going to vary depending on how the trailer is loaded, so you could end up occasionally...

  • 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.

    For your 2015 Toyota Tundra I would recommend the heavier duty SumoSprings part # SSR-610-47 since you will be towing and carrying such a high amount of weight. The lighter duty part # SSR-610-40 would still help, but not nearly as much as you would need the HD version would be the one to use. You would only notice either of these springs if you were to hit a pretty large bump when unloaded.

  • What Do Different Colors of SuperSprings Jounce Springs Mean
