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 have not installed them yet but they look just as described and am looking froward to seeing how they work. Plenty of instructions provided. Thanks!

2019 Toyota Tacoma

Couldn’t have been a simpler install! Total time was less than 15 minutes which included digging the floor jack out, blocking the tires and cleanup. Makes a heck of a difference in keeping the nose of the truck up when towing trailer or hauling 16 golf cart batteries.

Ev T.

Still awesome. A year later, have hauled up to 16 golf cart batteries with no issues due to the weight. A real help in getting the work done without the fear of bottoming out.



by:

Excellent product. Excellent service thru etrailer. The sumo springs make a huge difference in control while towing our small camper.

easy to install. Have ~500 pounds in my tacoma bed between a cap, sleeping platform/drawer system and cargo. These took up about 1/2” of sag and improved the ride

Installed easily on my '16 Frontier 2wd, came with great directions! Noticeable reduction in body roll while cornering and less squishy feeling from rear suspension with load. Thanks to CSR Ashley for her help!

Great customer service



by:
2017 Toyota Tacoma

The product shipped from e trailer as ordered and arrived as promised. Both went on easily for this 71 yr. old, but the metal mounts are heavier than those that came off so had to let out a little more thread than OEM. They lifted the rear of my '17 Tacoma TRD Off-Road about 3/4". The pickup does not 'rock' as much in turns and is a little stiffer over highway bumps. I've not hauled a load yet to give an honest opinion on that function of the springs. No complaints about the product and cudo's to etrailer for their sales and shipping folks.

Works as hoped and advertised. Easy to install, keeps the Tacoma level when pulling travel trailer. Stiffens ride when pickup is empty, but the trade off is acceptable.

So far they work great. Very happy

Product arrived quickly and was very simple to install. Exactly what I was looking for! Thank you etrailer!

Arrived on time. Easy to install. Only took about 45 minutes to put on my 2022 Nissan Frontier King Cab 4x4.

Toyota Tacoma

First of all I am not a technical person and purchased these solely on the advice provided by etrailer.
I have been towing a 25' travel trailer with a somewhat undersized truck(6 cyl Toyota Tacoma) and was experiencing some excessive 'bounce'. These SumoSprings addressed this issue quite well with no stiffness or effect when not towing. Completely satisfied with my purchase and appreciative of etrailer for the excellent advice.



by:

I've not installed them yet, but I rated four stars for customer service, I did order the blue by mistake and after one call and a speaking to a human quickly the return process was expedited, and the Black sumo springs arrived in just a few days . I expect them to perform well as verified in reviews by others.



by:
2010 Toyota Tacoma

Arrived sooner than expected. etrailer has always been top notch. The sumo springs really seem to be good on my Tacoma, half price of air bags . I have always ran air bags and kept a minimum of 10 psi. These seem to ride about the same as the bags did with 10 psi. Got the black sumo mediums to heavy . Seem great with 400 pound tounge weight. They did lift my truck about half an inch. I have bed topper and about 150 pounds in bed. I would recommend.



by:
2017 Toyota Tacoma

I installed the helpers on my Tacoma to help with the load of a car trailer hauling our old pick-up to car shows. They also help to keep the truck level when hauling loads of fire wood. The only issue that I have is that when empty, it gives the truck a stiffer ride.

Thank you Etrailer for your quick service and follow-up on your products.



by:
Toyota Tacoma

The SumoSprings for my 2020 Tacoma Off-road installed with ease in less than an hr. Very nice product. Will be a welcome addition when loading up the bed or pulling the utility trailer. Thank you Etrailer for the customer support.



by:
Toyota Tacoma

I've had these on my Tacoma for a year and they are great. Easy to install, and eliminates the "bottoming out" that I used to get whenever going over bumps, with a truckbed full of bikes or camping gear.



by:
2020 Toyota Tacoma

Product was easy to install it took me about 40 minutes, could be done in less time if you have impact. I have not pulled my trailer yet since I have installed it but it definitely looks like it will take the load of my 14-ft enclosed trailer. I installed them on a 2020 Toyota Tacoma to help with the squat in the rear of truck.



by:

Ordering was easy!!! Shipped right to my home address without any problems. Installed them same day as they arrived. About 30 mins from start to finish. They work just like they are supposed to!!! Very satisfied and will recommend they to everyone I know!!! Great job peeps!!! Keep up the great work!!!

  • SumoSprings or Timbren Suspension Enhancement For a 2017 Toyota Tacoma Pulling Car Hauler Trailer
    I recommend the Timbren Rear Suspension Enhancement System # TTORTUN4 over the SumoSprings Solo Custom Helper Springs # SSR-612-47 for your 2017 Toyota Tacoma TRD Sport. The Timbrens have a much higher weight capacity at 6,000lbs versus the SumoSprings at 1,000lbs. This will give you a better ride level and stabilization when you are towing your car hauler. A Equal-i-zer Weight Distribution System # EQ37100ET may be a better option if you only need the suspension enhancement when you are...

  • Recommended Rear Suspension Enhancement For 2019 Nissan Frontier Pro 4X Carrying 4 Wheeler In Bed
    We have just what you are looking for. I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-612-47 which has an 1800lb load leveling capacity which will prevent the rear suspension of your 2019 Nissan Frontier Pro 4X from sagging so bad when your Polaris Sportsman 800 is loaded up. This kit will also keep the factory unloaded ride quality so no need to worry about stiffening up the suspension too much. I included a video of the # SSR-612-47 for you to take a look at.

  • Recommended Suspension Enhancement for 2017 Toyota Tacoma with 2" Lift
    I have a solution for you, but because SuperSprings does not offer a lift spacer for the SumoSprings, using the # SSR-612-47 may not be the best solution in this case because of your lift. Instead, I recommend using the Timbren # TTORTUN4L which can be used with lift spacers like the # A25723-90AH00, which will help compensate for your 2" lift. The Timbren system won't effect your unloaded ride quality and allow the springs ample room for movement. I've linked some brief review and installation...

  • Recommended SumoSprings For 2016 Toyota Tacoma Carrying 1045lb Truck Bed Camper
    I would be happy to help! Since you already have a 2000lb Hellwig helper leaf spring installed in your 2016 Toyota Tacoma I recommend going with the SumoSprings # SSR-612-40. These will give you an additional 1400lbs of load leveling support while carrying your 1045lb truck bed camper, and will not affect the unloaded ride of your truck so no need to worry about them being too stiff. I included a video of the # SSR-612-40 for you to take a look at.

  • Height of SumoSprings SSR-612-47 and SSR-610-47 for Toyota Tacoma
    I checked with SumoSprings and the height of the spring is 4-1/2 inches for both the SumoSprings Solo Custom Helper Springs # SSR-610-47 and # SSR-612-47. These springs do fit different model years of Tacoma, and for your 2019 Toyota Tacoma, the correct fit are the SumoSprings Solo Custom Helper Springs # SSR-612-47. These will fit both the 2WD and 4WD versions of your Tacoma; I have added a link below to a video review for you to check out as well.

  • Suspension Enhancement for 2016 Toyota Tacoma Towing Trailer with Bed Cargo
    Based on how much you'd be carrying and towing the SumoSpring you'd want is the # SSR-612-47 which has the 1,000 lb capacity. But your best option is the RoadActive Suspenion kit part # RAS4514-SAT which gives you the support you are wanting while improving handling and stability beyond what the SumoSpring offers and do so without negatively affecting the ride quality.

  • Height of SumoSprings Solo Helper Springs for 2016 Toyota Tacoma
    I went out the warehouse and measured the 1,000 pound SumoSprings your 2016 Toyota Tacoma and they're right under 5 inches at about 4-15/16 inches. These are custom fit for your Tacoma as long as it has the factory suspension. If you've modified it at all let me know and see if we have another option that'll work for you.

  • Height of SumoSprings for 2024 Nissan Frontier
    The height of the SumoSprings Solo Custom Helper Springs # SSR-612-47 is 4-1/2". These are designed to have a 1/2" - 1" gap so if you have a lift you will need to measure to make sure they will fit. If the gap is more than 1" then they wouldn't work properly since the vehicle will have to sag even further before they engage. I have attached an installation video below for your reference.

  • Is Weight Distribution Needed With Suspension Enhancement on 2018 Toyota Tacoma?
    Those are very good questions and let's start with the capacities of both systems. The SumoSprings Solo Custom Helper Springs # SSR-612-40 has a 500 lb capacity and SumoSprings # SSR-612-47 has a 1,000 lb capacity, which means that is the highest amount of weight that the springs will actively still help your 2018 Toyota Tacoma's suspension. Anything over that and you won't see the benefits of the system. If 3,500 lbs is the max weight of your enclosed trailer when it is loaded then your...

  • Recommended SumoSprings for a 2022 Toyota Tacoma 4WD
    For your 2022 Tacoma you are going to want the SumoSprings Solo Custom Helper Springs item # SSR-612-47. These attach directly above the leaf springs so the block between your axle and leaf spring won't affect the springs function. I have linked the instructions below along with a review video.

  • Recommended SumoSprings for 2018 Toyota Tacoma with TRD Package
    For your 2018 Toyota Tacoma TRD 4wd the correct Sumo Springs are the Sumo Springs Custom Solo Helper Springs # SSR-612-47, which will replace your factory bump stops with a durable microcellular urethane bump stop. These are designed to help level uneven towing loads and fight sway, and are a great addition for any truck that is towing or carrying heavy payloads. I've linked a review video of these for you to check out.

  • Height of SumoSprings for 2023 Toyota Tacoma
    The height of the SumoSpring Solo Custom Helper Springs # SSR-612-47 is 4-1/2". Since you have a lift on your 2023 Toyota Tacoma you will need to measure to see if they will fit or not. There should be 1/2" - 1" gap once installed for the SumoSprings to work properly. If the space is larger that means your truck would have to sag that much more before they engage. Basically you wouldn't be getting the support you're looking for.

    If the loaded tongue weight of your trailer will be around 640 pounds, the better option between the two SumoSprings systems that you mentioned will be the higher-rated # SSR-612-47, which features a weight capacity of 1,000 pounds. The # SSR-612-40 that you also referenced has a weight capacity of 500 pounds so it may be a bit under-rated when hooked up to your fully loaded trailer.
