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.
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.
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.

The Sumo Springs make the ride stiffer on rough asphalt roads. When the road is relatively smooth the ride is exceptable. They dont seem to handle the load like a air bag or progressive leafsprings but are working for my application right now.

I love giving reviews before I've had a change to tow my camper with them on. I did drive around the block after I put them on. I think the ride will be a bit harsher, but it should much better with a load on. I did try to remove the spare tire, that's when I found out I didn't get a jack or wrenches when the truck was purchase two years ago. Better now than when there actually needed.
by: Tom 05/12/2024
The Supersprings smoothed out the camper trailer ride especially noticeable on bumpy roads. A good product that does what it’s supposed to do. If I ever get another camper I’ll get Supersprings again.

Just installed the Sumosprings on my 2022 Tacoma,easy install, took about a hour.Truck rides the same with no load on it and will see how it does next time I tow the trailer.Shipping was fast and well packed.
by: Javan09/02/2024
This product absolutely solved the problem I needed it to; the truck no longer bottoms out violently over bumps if the bed is loaded. This is a cheaper solution than a lift.
There is a change in the behavior of the rear of the truck; but it's not detrimental to normal driving; it just has a different oscillation mode than the front. This is noticeable over whoops. It's not really a problem, but it's a noticeable change in handling off-road.

my sumo springs are great and do not worry about my bed hitting my tires. thanks
by: Robert 05/02/2024
Extremely easy to install. They allowed me to tow my daughter's trailer, which is much bigger than mine, they helped control sway and squat.
by: GonMV02/08/2024
These are great when they are fully loaded. I bought them to help when towing my boat and they work great for that. Unfotunately though when they are not loaded they're like a rock and my Tacoma TRD Offroad rides like its bottoming out at every little bump because they are much taller than the standard bumper. It feels like a rock when you come down onto them. I was hoping that the lighter weight version would not do that.

very simple install completed with basic tools in my driveway in les than an hour. These have done a great job leveling my Tacoma with a camper loaded or heavy loads. I have not towed with these installed yet but would expect great results and prevent rear sag

We installed the SumoSprings SSR-612-40and replace the OEM shocks with the Rancho RS9000 XL on a 2016 Nissan Frontier. When pulling a trailer (KZ Sportsmen Classic 160QB)the back of the truck sag only 1 1/4".I have used Sumosprings in the past and with great results.

Awesome experience with etrailer!

2016 Toyota Tacoma
Installed and the rear axel of a 2023 Toyota Tacoma TRD Off Road, no suspension lifts and stock tires and rims.
My Application: I regularly tow a tandem axel 16 foot cargo trailer on the weekends. The trailer stores and transports 3 dirt bikes and gear. It weighs about 3700 to 4000 lbs. I do occasional home projects as well where I'm hauling lumber, stone, (Typical truck stuff).
The cargo trailer was really causing my truck to squat more than I like. I'm well within the tow rating of the truck, but handling at highway speeds was not great. I ordered the lower capacity Sumo Springs as I didn't want to make the truck ride really stiff and bouncy. Installation of these was not bad. I do recommend re-torquing them after use as called for in the directions, mine needed it. They really helped address the squat problem when the trailer is connected. I was surprised how much they also reduced the sway when towing the trailer. The ride is stiffer, but not too much. I'm very happy and would recommend to a friend, and would purchase again.
by: Allan08/31/2023
Just finished changing out the old and putting these on my stock 2017 SR5. Took this old man probably 20 to 30 minutes to complete. Test drive feels like a totally different truck. The Tacoma sag is gone and actually feels like it raised the back end. Wife approved!!

I often pull my 3800lb boat with me 2021 Tacoma, I needed some extra help with the bouncing and sway control, these Sumo Springs are the best thing I could have done, it handles like a completely different truck now. 100% satisfied.

Toyota Tacoma
I put these on my 2020 Toyota Tacoma TRD Sport, primarily enhance the ride while pulling my 21 foot travel trailer. I can tell you they absolutely did that. The ride seemed a lot more confident, shut down any degree of porpoising, and felt sure on any turns. The ride also felt more rail-like at a higher velocity.
When not pulling a trailer, they eliminate any sense of roll, but on a Sport trim it really wasn't a concern. The only downside is the rather unforgiving jolt you you'll feel when you go over something like a speed bump. If you have anything in the bed of your truck while doing so, it will achieve a fair degree of vertical lift. Just make sure you're wearing your seatbelt and have your coffee well covered.
All in all I'm happy with these as an alternative to finicky airbags. And they were very easy to install, literally 20 minutes for an codger like me. Just set em and forget em.

I have an ARE Overland camper shell on my 2019 Toyota Tacoma. Installed these to help with the over all ride especially over hard bumps. Sounded like I was hitting the bump stops hard. Installed and ride did improve for the back. Also less body roll. P.s. George J is the best! Always on it when it comes to getting parts out!.
by: Mitchell05/01/2022
2021 Toyota Tacoma
I added these in my Tacoma to help pull my 3200lb (dry weight)camper. These in conjunction with the WDH made the rear of the truck drop 1/4 of an inch. I haven’t noticed any change in the ride while I’m not loaded.

We put SumoSprings (blue) shocks on our ‘21 Frontier to pull our Casita camper. What a world of difference it made for the better. The ride is smoother and we seem to have a better control of the camper being pulled. We love them. etrailer is THE place to get these.

The sumo springs are awesome!! I have them installed on my Nissan Frontier and tow a small RV... The ride is perfect, rear leaf springs do not sag as much.. Great quality product!!

Very easy and quick install. I was a little worried about the ride quality being affected, but there is no difference. The Sumosprings have helped the truck retain its ride hide while I have the bed loaded.

The Sumosprings have been working great! They were extremely helpful on a 2200 mile road trip this fall.

2017 Nissan Frontier
Installation on my Nissan Frontier was a breeze. My trailer has 4-500 lbs. of tongue weight, and these springs do a good job of reducing squat and sway. I would buy them again. The only reason for 4 stars is that when unloaded you only get about 3/4" travel before these springs kick-in. In the winter (cold temps) they are hard as a rock, and hitting even a smaller bump can be a real kidney-puncher. Almost as bad as a 1 ton truck. I wish there was an easy way to remove them for the winter when I rarely tow.
by: Jason 05/23/2023
2016 Toyota Tacoma
They work excellent with a heavy load in the bed and when towing my travel trailer but make the rear little harsh over bumps when not loaded. Not a deal breaker though, overall very happy with them. 2016 Tacoma SR.

Works. Makes the truck level without adding airbags,spring loaded shocks. Etc.
by: Alex03/11/2018
I was shopping for a set of Sumosprings for my truck. I got a great price and excellent service from etrailer. They kept me updated on the status of my order and the Sumosprings arrived in a very timely matter.
I highly recommend etrailer and will be doing business with them in the future.

- Jounce Bumper Helper Spring Options for 2021 Toyota TacomaSome 2021 Tacoma were equipped with 3 leaves in the springs, some with 4, so you'd just need to take a quick peek at what you have to determine which Timbren kit you'll need, as I have no way to look up how your truck is equipped. For a 4WD with 4 leaves in the spring pack, use # TTORTUN4, for 3 leaves use # T72FR. For 2WD vehicles with 4 leaves, use # T62FR or # T72FR for 3 leaves. This being said, the Timbren systems offer much more support than what you'd actually need to counteract...
view full answer... - Comparing Leaf Help Springs And Jounce Springs For A 2023 Toyota Tacoma 4WDJounce springs will sit on the frame and come into contact with the axle as the suspension compresses. Typically the vehicle manufacturer will place a rubber-type material here to prevent the harsh bump between these two components when heavily loaded or hitting rough terrain. These manufacturer jounce bumpers are usually pretty small and only get used when the vehicle is loaded down so upgrading to larger ones like SumoSprings will have them activate sooner and provide you with more load...

This will be an excellent blend of support and ride quality that won't make the vehicle unpleasant to ride in.

The one you choose will depend on your usage for your Frontier. The SumoSprings # SSR-612-40 is the lighter option with a weight capacity of 1,400lbs. Do remember that these will not increase your payload or towing capacities but are designed to assist the factory suspension. These are the ones that I recommend for those that are only hauling lighter loads occasionally and don't always...
view full answer... - Recommended Suspension Enhancement for a 2021 Nissan FrontierI do have an option for you but there are currently no air bag suspension enhancement options for a 2021 Nissan Frontier. Instead, I recommend the SumoSprings Solo Custom Helper Springs part # SSR-612-40 which provides support while towing or hauling while also not negatively affecting ride quality too much.
view full answer... - What Suspension Enhancement do You Recommend for Reducing Sag on My 2021 Toyota Tacoma?You are definitely on the right track with the SumoSprings. For your 2021 Toyota Tacoma, I recommend using the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-612-47. The reason why is because this model of SumoSprings will provide your Tacoma with 1,800 pounds of load-leveling support compared to the 1,400 pounds of support of the # SSR-612-40. This load-leveling support will definitely help decrease the 1.5 inch sag. Also, the SumoSprings # SSR-612-47 provide progressive load...
view full answer... - SumoSprings Custom Helper Springs For a 2024 Nissan Frontier King CabYou will want to select either the 1,400LB # SSR-612-40 or 1,800LB # SSR-612-47 SumoSprings Solo Custom Helper Springs for your 2024 Nissan Frontier King Cab. The only difference between these is the amount of capacity they are capable of supporting and the color of the part itself. If you are only occasionally hauling heavy loads the lighter option would work the best for you. These will have the least affect on the quality of your ride when unloaded as well.
view full answer... - 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...
view full answer... - Super Springs SumoSprings for Rear Axle of 2016 Toyota Tacoma I checked with Super Springs and the SumoSprings Solo Custom Helper Springs # SSR-612-40 that you referenced are indeed the correct springs for your 2016 Toyota Tacoma.

I have attached the written installation instructions that you can check out as well.

With that being said, for higher capacity springs on your truck to give you the support you need and eliminate sag, I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-612-40.

These are designed to be held in place under the U-bolts of a spring over axle and will likely not attach to your 2020 Toyota Tacoma with a spring under axle. I do not see that they have kit for your Tacoma with a spring under axle. If you can send me photos with measurements of your axle to frame I can check with SuperSprings to see if they have a different kit that may work with your Tacoma.

- Recommended SumoSprings For 2016 Toyota Tacoma Carrying 1045lb Truck Bed CamperI 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.
view full answer... - SumoSprings for 2019 Nissan Frontier Pro-4XHi Jeffrey; we don't carry lift kits but you can definitely use SumoSprings on just the rear of your 2019 Frontier. The # SSR-612-40 you were looking at would be perfect for additional support and what I recommend. I also recommend double checking your rear suspension. I'm not sure what you mean by a "bit of weight" but if you're bottoming out all the time you may have some other parts that need replacing.

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. Both systems are confirmed to fit your 2017 Toyota Tacoma. With this in mind, any jounce style spring...
