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.

Video Transcript for SumoSprings Solo Custom Helper Springs Review

Speaker 1: Today, we'll be taking a look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle. You'll want to use eTrailer's fit guide to determine the correct kit for your vehicle. This is what our SumoSprings look like when installed. Yours may look a little different depending on your vehicle.They're gonna replace our factory jounce stops and sit right between our frame and our rear axle. So whenever we're carrying a heavy load, they're gonna give us that extra support that we need. The way our SumoSprings are gonna work is when our suspension starts to sag from the heavy load, these are gonna absorb a lot of that weight.They are gonna work independently from each other so it's gonna help with those off-center loads.

Our springs are gonna have a progressive rate to 'em. So if we have a light load, they're gonna compress softly, still giving us that comfortable ride. But the heavier load we put on 'em, the more they're gonna compress and the more firmness they're gonna have to them.Now comparing to our factory jounce stop, you can see there's a big difference in height. These are gonna give us a lot more compression, whereas our factory jounce stops are really just preventing the axle from hitting the frame.We have a water tank at the bed of our truck as a heavy load or to simulate the tongue weight of a heavy trailer or a fifth wheel. So as I take the truck through my test course, I can definitely tell that there's a load back there.

The engine doesn't seem to be strained that much, but the bumps are extremely harsh and I can definitely feel it resonating through the seat.When I come to the slalom course and I'm going through the turns, it definitely has a lot of body roll and I just generally feel like I need to slow down because it feels likes it's leaning a lot and it's not responding quickly enough to the turns.Now that we have our SumoSprings installed and I have the same load back there, when I'm driving through our course, I can immediately tell a difference. It's much of a smoother ride. Going over the bumps really doesn't feel like anything's back there and it's just a lot more comfortable.When I come into the slalom course, it definitely feels a lot more stable and it doesn't seem to sway as much side to side and it just generally feels like it wants to go faster.These are made of a durable micro cellular urethane that works in temperatures from -25 degrees to 200 degrees Fahrenheit, and resists damage caused by oils, road salts and UV rays. Compared to air bags, these are maintenance free option with no tubes to run or air pressure to maintain. Both will help level your load and provide a smoother ride.

Airbags can be adjusted to suit your needs whereas the SumoSprings are a fixed option.That completes our look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle.

Fantastic. has no impact on ride with no weight in truck. I installed them on my Toyota Tundra 2007 following a frame replacement. they sit about 1-2 inches off so they do not engage until loaded. significant difference with any load over 500 lbs. easy to install. 722454

Product was delivered and was a breeze to install! A friend happened to be around when I got started and we had them both installed in less than 20 minutes with the help of a car lift available to us. Didn't quite raise the bed of the truck as far as I hoped it would, but still a great product! Guess that's just the Baja Edition? But did find out I might need different shocks so that will be my next step soon. 508762

Great product ! Does all it claims and more than i expected. I leave my 5th wheel hitch mounted yr. round and haul bins of sand when I plow in the winter, so it's helping all the time. I can see and feel a difference in hauling our 30 ftr. Doesn't change the ride at all like just about anything else you'd need to do to get the help these give you. Easy install too! 347625

Still goin strong. I’ve had numerous campers even a Tundra owner inquire about what I’ve done to level my truck for the load. It totally out does more springs! When and if they fatigue, I’ll buy em again.

2009 Toyota Tacoma

Purchased for a Tacoma 4 dr, long bed, with a fiberglass cap. I have the TSB/recall replacement spring pack. With this set up I had a decent ride, and better support over the OEM springs, but still see that the springs provided only minimal improvement when loading in the bed say 300-500#. If so loaded (camp gear, MC gear, 2-3 persons in cab) on moderate unpaved roads the OEM springs were at max load and had we too much frame sag. WITH the addition of the SumoSpring kit I found my truck when UNLOADED handled the same, but did have less body roll in the rear. At rest the frame rail is just touching the SumoSpring and wheel well to ground is 36 1/2" with P245 tires. When LOADED as detailed above, the rear feels firmer, has less body roll, and does not sag to excess like the OEM spring pack. Very satisfied with results. A very nice enhancement at a excellent price point. Kit is simple to install and should require no regular service/adjustment. 353831

Re levels the poor Tacoma leaf springs. But definitely stiffens the ride on the off-road Bilstein shocks. If you carry a reasonable amount of weighted recovery gear at all times like I do, these are worth adding to your suspension. I installed them in 20 minutes. 561552

Truck type: 2008 Toyota Tacoma SR5 Prerunner 2 WD Installation: Easier than an oil change. Took me about 8 minutes per part. I lifted the truck's receiver hitch 3 or 4 cm before starting. 19mm deep socket was the only tool needed. Did not even remove the U-bolts, simply loosened, removed old OE rubber pyramid bump part, and replaced with the SumoSpring parts. Results: fender height was normally 36.5". With RV on at 400 pounds hitch weight, compression was 4" before SumoSpring. After install, compression is 1.5". Leveling problem solved. As for ride without RV, I found an old bumpy concrete street nearby, ride quieter and smoother. On corners, truck is more stable and does not rock as much due to "centrifugal force". Overall: I like what I'm seeing. Will write again once I road trip the RV. 574225

2013 Toyota Tundra

Installed the SumoSprings foam helpers on rear of 2013 Tundra to smooth out the bumps in the interstates when pulling our 7600 lb travel trailer. Transaction and shipping from E-trailer was seamless as always. Installation took maybe 30 minutes and I didn't even remove the wheels. Unloaded and solo, there is maybe 1/8" clearance between the frame and the top of the pads so they engage very quickly when load is added. When I add my 950 lbs of tongue weight, the rear sag of the truck is reduced from 3.5 inches to 2.75 inches. This reduced sag required a re-adjustment of my Equal-izer WD hitch which was by far the most time consuming work. With adjustments made, the ride is noticeably better on the interstate. The loaded ride is a little more firm but the hard bounces generated from my frame hitting the stock spring jounces is eliminated. Unloaded I can't really tell any difference in ride. I researched air bags and the other non-air-bag spring helpers, but I believe this product was the best addition for the Tundra. Tundra's do not have a lot of cargo capacity anyway, and Sumo told me they design this particular product for the Tundra specifically to create a balance between reasonable cargo loading and stiffness/ride quality. They said that is why this product looks different for different applications - they design each piece for the specific truck and load/spring characteristics. 154660

My Nissan frontier would ride on the bump blocks when loaded so I installed these sumo springs and I have been very happy. They have made my truck much more useful to me even when I am using it off road on our farm or pulling a trailer. I would recommend these to anyone who needs a little more support in the rear springs for heavy loads. The installation was very easy as my Nissan did not even require me to jack up the vehicle, I simply loosened the leaf spring U-bolts and installed the new Sumos. then I retorqued to the specified value on the U-bolts and that was it was very easy on my truck. Also the price was very reasonable for the value received, I will definitely shop at etrailer again. 736192

Bought them because if I loaded two dirtbikes in my Nissan Frontier, it would bottom out occasionally. 1 bike and the truck was fine. They are pretty good for two bikes loaded, but make the ride a bit rougher when the truck is empty. Since I only load two bikes twice a year, I think I would have been better off leaving it as it was, and drive slower those times. If you load down the truck once a month or more, get them. It does ride harsher but not extremely so, enough to jiggle the coffee in your hand when you are sipping it. 721007

Install was easy, air impact driver helped for sure. Firmer ride empty than expected, but not overly so. From watching videos and reading adds did not expect to notice difference unloaded. Loctite was dried up in tube, was in process of install when I realized that. The true test will come when loaded or RV trailed is being towed. 2005 toyota tacoma trd 680871

Toyota Tacoma 2011 4 door short box Sport Great product. Other reviews said that it was easy to install Ya right, It was easy to install to much of my dismay. When it is installed it said that you have some space between the leaf spring and the sumo spring I did not, it is in contact with the leaf spring on my truck at all times. The ride is a bit stiffer when empty but it gives the truck a little rake that I like. Now when I have about 700-1000 in the back I have no problem with sag and the truck rides smooth. If this Tacoma ever wears out I will put one of these on my next Tacoma. 635661

Great service and prompt delivery from etrailer. I haul a small backhoe on a trailer with my Nissan Titan. The SumoSprings solve the small amount of rear sag I experience when hauling but do not affect ride during everyday driving. The product is great and I would recommend them to anyone experiencing similar issues. My first purchase from etrailer has exceeded my expectations. I would recommend them as well. 604797

So far, so good. Installation on my 2014 Tacoma went very well. The truck now sits about 3/4" higher in back and feels a little firmer in the ride. I plan to hook up my RV trailer this week. It looks like these will work just fine to eliminate the "tail sag" that so many Tacoma owners report. 526827

Overall the product was very good and easy to install. I used red Loctite on all the hardware components and I have not had any issues. I will say the product helps to reduce sagging with heavier loads in the bed of the truck. The springs did increase the rear ride height to that of slightly higher than the front end. When the truck is unloaded the ride of the truck is a little more stiff than I prefer. I would buy this product again. 524478

Awesome product. They have taken some strain off the leaf springs during long heavy drives. Biggest difference has definitely been the added stability on the freeway. It has also helped minimize body roll when cornering at speed. Might have to invest in pair for the front of the truck! 479254

I put these on a 2016 Tacoma Off Road that tows a 4000 lb travel trailer. They have little or no effect on the truck when empty, but limit the suspension travel with the 450 lb tongue weight of the trailer. I far prefer them to air bags, which ave always eventually leaked down. 439574

Beginning in April 2015, I have loaded my 2014 Toyota Tacoma PreRunner pretty heavily every year and make the trip back in forth between Houston and Austin in support of the MS150 bicycle ride. Last year I could tell just how loaded my truck really was and it felt unstable. It was after that, that I installed the SumoSprings. This year my truck was just as loaded but the ride was much more stable and there was very little sag in the suspension. I'm sold. 375227

My Sumo Springs Supersprings are working out Great on my 2016 Tacoma. At first they felt a little stiff, but I soon got used to the way the truck rides and I'm very happy. Last Spring I needed to get some paving bricks for a small project in the garden and I found an ad for "About 100 Bricks" on Craigslist not too far from home. By the time I got the load of bricks in the truck, the actual number was closer to 300. Boy, was I glad that I had the Sumo Springs installed on the truck! I did take it easy on the ride home, but the Supersprings did the trick. I regularly use my truck to carry equipment for my small business and while it not as heavy as 300 bricks, my truck rides nice a level and I don't bottom out when there's a pot hole or a bump in the road. My thanks to Sumo Springs and Etrailer. 343816

Product arrived in great shape and packed well from etrailer.com. Installation was simple and went smoothly. Real test will be a couple of weeks out when I tow the camper and truck out to Big Bend fully loaded. Even unloaded, the truck felt a little less bouncy, they dampened the suspension a bit. I'm looking forward to a full test in a few weeks. 337400

    I called my contact at SuperSprings and they informed me that in order to obtain the specifications as to how many foot pounds of torque needs to be applied to the factory u-bolts, you would need to obtain your VIN and contact the manufacturer. Another option you have would be to contact your local repair shop who has access to a program called, "ALLDATA". Unfortunately, these are the only options I have for you to determine the correct torque spec for the factory u-bolts on your 2011 Toyota...

  • How Much Clearance Between SumoSprings # SSR-610-40 and Frame on an Unloaded 2015 Toyota Tundra
    It's going to vary some from vehicle to vehicle just because of how your truck rides. However, I reached out to SuperSprings and they told me that a half inch to an inch of clearance between the spring and the frame is fairly standard. The SumoSprings Solo Custom Helper Springs # SSR-610-40 including the brackets are 6 inches tall. So if you need to determine exactly how much space will be between the spring and the frame of your Tundra you can always measure.

  • Are the Light Duty and Heavy Duty SumoSprings the Same Height for a 2015 Toyota Tundra
    Yes, I would say that is a fair assessment of SumoSprings # SSR-610-47. the capacity is higher as well at 1,500 pounds. And of course it also fits a 2015 Toyota Tundra. Both it and # SSR-610-40 even share the same instructions.

  • 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.

  • Will Sumo Springs for Toyota Tundra Slide Off Bumper Stops
    I spoke with my contact at Super Springs and she said the SumoSprings Custom Helper Springs Kit # SSR-610-40, which you referenced, are designed to replace the factory bump stops. The springs are bolted to a mounting bracket held down by Ubolts so they are very secure. Additionally, when you have a load on the springs they will be compressed. So no, the springs will not slide off when going down the road with a load. I have included a link to the installation details for you to check...

  • Which SumoSpring Kit for 2017 Toyota Tundra
    I'd go with the lighter duty SumoSprings for your 2017 Toyota Tundra for the reason you mentioned. The heavier duty ones will be much harsher. I only recommend the higher duty ones for people who plan to be at the capacity of their vehicle most of the time when travelling. The part # SSR-610-40 would be the better option. You'll most likely have to use lower spring bar tension with your weight distribution system as well.

  • Height of SumoSprings Campatible with 2008 Toyota Tacoma PreRunner
    The Super Springs SumoSprings Custom Helper Springs # SSR-610-40 are confirmed to fit on your 2008 Toyota Tacoma. They will install in place of the existing factory bump stops and measure 6 inches tall. There should be some space (approximately up to an inch usually) between the helper springs and the frame when they're installed so they will not raise your truck. I've attached a video of the springs being installed on a 2007 Tacoma for you to see.

  • Suspension Enhancement Recommendation for 2008 Toyota Tundra
    We have just what you would need. The Timbrens like part # TTORTUN4 will give you additional suspension support without the hassle of dealing with air bags but they do have a reputation as being somewhat harsh. What we have found is the SumoSprings like part # SSR-610-40 give you the easy, maintenance free support without the harshness associated with the Timbrens. This would be our recommendation.

  • Is It OK For Super Springs SumoSprings to Touch Frame of 2005 Toyota Tacoma when Truck is Unloaded
    Typically, you do want a bit of space between the spring and the truck frame when the truck is unloaded. However, if your Super Springs SumoSpings # SSR-610-40 touch the frame of your 2005 Toyota Tacoma when it is unloaded it will be okay. The only thing you may notice is a bit stiffer of a ride since the springs will engage more quickly once the truck is loaded. From the install photos taken when we installed these springs on a 2007 Tacoma, it appears that truck had very little to...

  • Jounce Bumper Suspension Enhancement Recommendation for a 2015 Toyota Tacoma

  • Suspension Enhancement Recommendation for a 2008 Toyota Tacoma
    Both the Timbren Suspension System part # TTORTUN4 and the SumoSprings part # SSR-610-40 (which only have a 1,000 lb capacity),have been confirmed to fit your 2008 Toyota Tacoma, but I would recommend the SumoSpring kit over the Timbren because they tend to provide a smoother unloaded ride quality over the Timbrens. There is a guy here that has had both setups on hit Ram truck and he like the SumoSprings much better. He said he could hardly tell they were installed when the truck was...

  • Suspension Enhancement Recommendation For 2005 Toyota Tundra 2WD
    For your 2005 Toyota Tundra I recommend The SuperSprings Vehicle Suspension, part # SSR-610-40.

It helps prevent sagging and bottoming out when carrying heavy loads. This system is easy to install by replacing the bump stops on your vehicle. There is no drilling required for installation. They will not affect the ride of your Tundra...

  • Weight Distribution and Helper Springs for a 2008 Toyota Tundra 2-Wheel Drive
    Weight distribution should be used any time the gross trailer weight is at least 50 percent of the gross vehicle weight. In this case the trailer is more than half of the truck weight so I do recommend weight distribution. Weight distribution basically uses the leverage of the spring bars to apply the tongue weight of the trailer more evenly to all axles of the tow vehicle and trailer so it will help with stability and rear end sag. Suspension enhancement products help on the truck side...

    The SumoSprings Solo Custom Helper Springs - Rear Axle part # SSR-610-40 will work well to eliminate the rear sag of the 2020 Toyota Tundra TRD Pro 4x4. I confirmed with SumoSprings that these springs are a fit for your model.
