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.

Always great customer service and speedy delivery.
SumoSprings easy to install, no issues.



by:

Added 2” spacers on each side so the Sumosprings touch my frame. Relatively easy to install, but centering on the frame was a challenge as the directions tell you to touch the wire harness bracket. I elected to be slightly off center so the bracket did touch to prevent movement and wire damage. Also, once initial installation is performed, you must remove to tighten, which is not in the directions. Overall, the ride has not changed at all and it helps eliminate the drop from my trailer. Highly recommend!



by:

Always the fastest shipping, outstanding customer service and high quality products.



by:

Received very quickly. Exactly what I wanted and ordered. Thank you!!!



by:

Very easy to install and worked well.



by:

These springs perform as advertised. They were easy to install on my 21 Bronco and I have not been disappointed. I've pulled a trailer from Texas to Utah multiple times with my Bronco and I have not experienced any squatting. I also haven't noticed any decline in comfort of my ride. I highly recommend if your looking for helper springs for trailering.



by:

Great product, fast shipping!!!!



by:

Good product unfortunately it did not solve my ride issue but not at fault of the helper springs. Just bad engineering by GM. The helper springs were very easy to put on, less than an hour to put both front and rears on.



by:

Package arrived intact only 5 days after ordering. Contents undamaged and well packed. On my new 2024 Toyota Tundra the installation was very simple, straight-forward and easy. In my garage I raised the rear of the truck with a floor jack, gathered my tools and started about 45 minutes after the package arrived. Took me about 20 minutes on the drivers side because I lacked any previous experience with this product. Only took about 10 minutes for the passenger side because I was more comfortable after doing the drivers side. I didn't even have to remove the rear tires. Keep in mind that I am a very mechanically inclined yet 68 year old guy laying on a creeper underneath a wet truck. The mounting brackets are very heavy-duty and thickly painted. Actually heavier duty than the originals. Bolt holes in the brackets were exact matches for my Tundra. After lowering the rear of the truck back down there is still approx. 3/4" clearance ( previous 6" clearance measured at the original factory bump-stops prior to removal) between the bottom of the Sumo helper and the axle rest. This is about the amount of clearance I was hoping for---make contact at about 5-1/2". Leaves me about 3/4" free travel during everyday, unloaded driving. Without the Sumo's my truck sagged 3" with 575 lbs camper tongue weight. Raining outside so I'm not going to hook up my camper just to measure the difference today. However, if it now sags even 1 to 1-1/2" less than before, I'll be a happy camper (pun intended).
I gave this a 5-star rating because I received everything exactly as advertised. Also because I can see how this product will absolutely make my camper-towing experiences much more pleasant and safe. And the Limited Lifetime Warranty certainly was a factor. I usually don't take time to write reviews but I was so impressed with the overall quality of this particular product and the ordering process that I felt I owe them that much as a tip.



by:

Easy to follow instructions. Maybe 45 minutes to install using no power tools. Use an 18" long extension on a deep socket allows you to tight U-bolt nuts without removing the wheels. Otherwise plan on removing the wheels to make your life easier. Also the driver side is the tighter space to work in. Do that side first. Passenger side is super easy and a great way to finish the project.

Haven't towed the camper yet to see if it reduced the squat or not.



by:

Installation and function as advertised.



by:

Installation was pretty straightforward. The addition of this product did make my truck ride a little stiffer, but not rigid by any streatch. Hooked up the trailer today. Two things that I noticed right away; 1. The truck no longer squats with the trailer attached. 2. The annoying tail sway at highway speed has been greatly reduced.



by:

Since putting these on, it has made an incredible difference in the ride and handling, you do not realize how crappy the stock OEM parts are compared to these.
My 2024 Toyota Sequoia handles fantastic and without the SAG and lean



by:

2023 Tundra SR5 TRD Sport. Install was pretty easy, do take the tires off, makes it a lot easier. Just note that the bolts towards the back of the truck will need to be put in and started prior to the other 2 bolts due to the spring partially covering the hole. See the pics and you can see this. But I did finally tow my 9k camper with these installed and it took out the sag of the truck and the floating side to side was next to zero. And the stuff inside the camper wasn't tossed around near as much as it was without these springs installed.



by:

They really improve the cornering, and trailer sag.
If your at all a DIY person you'll have no problem installing these helper springs.
The only reason I don't give them a five star review is that their just installed andvI want to see how they hold up.

  • Recommended Suspension Enhancement For 2024 Toyota Tundra Crewmax
    Hello David, thanks for reaching out. Between the TImbrens and the SumoSprings for your 2024 Toyota Tundra I definitely recommend the Sumos. They have a progressive spring rate so you don't get as rough of a ride when you are unloaded. Since your hitch weight will be about 635 lbs, I recommend the blue Sumos part # SS46PV which are the 1,400 lb capacity. This will give you that nice middle ground between suspension support and ride quality. They are super easy to add on too. Just keep...

  • Which SumoSprings Kit Fits 2024 Toyota Tundra with 4 inch Lift
    Hey Kirk, for the SumoSprings kit part # SS46PV that fits your 2024 Toyota Tundra you'd need to use the Timbren spacer blocks part # A25723-90AH00 to take up that extra space created by the lift. You'd need 4 of these per side as these are 1 inch spacers.

  • SumoSprings for 2025 Toyota Tundra 1794
    Hello again Monty; I would get the black SumoSprings Custom Helper Springs # SS66PV. These have a capacity of 1,800 lbs so it gives you a bit over the blue without overdoing it. SumoSprings are a great choice if you don't want to go with the air bags since they have a minimal impact on ride quality. That is another bump stop in your picture to help prevent bottoming out. The SumoSprings will engage long before that would so it won't impact their functionality.

  • Do I Want Sumo Springs or Timbrens to Pair with My Weight Distribution Hitch?
    Hello Barry, Since you already have a weight distribution (WD) hitch and are only experiencing a little rear sag, I recommend going with SumoSprings. I typically only suggest Timbrens for those who are towing heavy loads regularly, as they can create a noticeably harsh ride when the vehicle is unloaded. Given that the sag is “not much but noticeable,” the SumoSprings Custom Helper Springs Rear Axle # SS46PV (blue) should be a great fit. These are rated for 1,400 lbs, while the yellow...

  • Will SumoSprings Kit SS46PV Help 2025 Toyota Tundra with Camper
    Hey Carlos, the SumoSprings kit part # SS46PV would be a great idea to help provide your rear suspension with additional support when you are carrying the heavier camper that you have. Basically it would just allow your air suspension to not have to work quite as hard while also improving handling and reducing sag.

  • Will SumoSprings Fit 2023 Toyota Tundra TRD With Lift Kit
    Hey Joshua! All of the SumoSprings like # SS46PV are designed to fit the Tundra at stock height. SuperSprings does not offer additional spacers to make up for the height difference so these won't work on your Tundra TRD with the lift. What you can use instead is the Timbren Suspension Enhancement System # T45MR. You will also need the Spacer Kit for Timbren Suspension Enhancement System # T33AV. If you don't like the Timbren the only other option would be to add an air bag system like...
