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.

2016 Toyota 4Runner
These sumo springs work great on my 2016 Toyota 4Runner. When towing a 3.5k lbs load, the rear sag was significant and negatively impacted the handling. Now with these Sumo springs the rear sags only about 1" when the trailer is hooked up.
by: Albert02/25/2023
2019 Toyota 4Runner
This review is based purely on the installation. It took as long to jack up my 4Runner, place jack stands under the frame, and remove the tires as it did to install the Sumo Springs. I installed these to lessen the squat of the 4R while towing my boat and my camper (WD hitch used while towing the camper). The Sumo Springs sit just above the real axel which should greatly reduce the squat and lessen the bounce while towing. Went this route based on other 4Runner owner's reviews.
by: Nick 03/22/2024
Takes the roll/bounce out of the 4 Runner with the stock suspension.
I have two K-9's that add about 240lbs to the rear. This assist in reducing the sag.
I also installed them for the front to control the nose dive during braking.
by: Brent10/11/2021
I gave the SumoSprings an initial rating of 4-stars because they do work as advertised. During the first thousand miles I've driven since installing them on my 2019 Toyota 4Runner, I have noticed they contact the rear axle much sooner than the OEM bumper stops which serves to quickly increase the suspension's resistance to any further downward motion of the truck's body - which not only dampens excessive rear end "dipping" on rough terrain, but also works well to prevent any appreciable rear end squatting from the tongue weight of my heavy 2-axle utility trailer.
I reduced my initial rating by one star because, while they centered on the mounting bracket holes in the same manner as the OEM bumper, I wasn't able to center the SumoSprings over the rear axle even after pushing them as far forward as the elongated bolt holes would allow.
Since the center of the SumoSpring pad (midway in the adjustment range of the elongated bolt holes) is in exact vertical alignment as the center of the OEM bumper, the only explanation would be that the 4Runner's coil-spring rear suspension has a slightly arced rear-axle "full travel" range as it rises upward from the lowest to highest position. If that "full travel arc" moves the axle to its rearmost position when the suspension is at full compression (where it contacts the OEM bumper), the "full travel arc" would then move the axle about 1/2" forward during the downward portion of the arc back to the normal ride position.
Therefore, since the surface of SumoSpring's long cushion pad is very close to the axle when it's in the normal ride position, that would explain why the SumoSpring at its farthest forward adjustment position is still about 1/4" to the rear of being centered on the axle(even though the SumoSpring in that position is now a bit further forward from vertical center of the OEM bumper).
However, since the rear axle's upward travel moves it slightly to the rear (and more toward center-mass of the SumoSpring's cushion pad), perhaps it won't suffer any premature deterioration or failure - but only time will tell about the SumoSpring's durability and longevity.

After 70,000+ miles of both highway and off-road driving with and without a trailer in tow, I am upgrading my original rating to 5-stars because the bluemedium SumoSprings have performed exactly as advertised and show no signs of degradation in either wear, appearance, structural integrity or any noticeable deformation after being hammered unmercifully by the tongue-weight of the trailer I frequently tow along with the “moonscape” off-road terrain and even worse conditions of the roads I usually travel . Even though the SumoSprings still lacked ¼” from being perfectly centered on my 2019 4-Runner’s rear axle housing after installing them as far forward as their elongated slots would allow, my assessment of the suspension’s compression arc moving the third-member a bit to the rear on its upward swing proved to be true since the “shiny spots” of the contact points on the rear axle housing are well-centered. Unlike a Jeep Wrangler with an extremely stiff “hay-wagon” ride and having “no butt” or cargo space that protrudes more than a few inches past its rear wheels to strike the ground after traversing a sharp terrain -off, the largerlonger 4-Runner with a more comfortable ride has a lot of rear body protruding past its rear wheels – especially with a trailer hitch draw-bar attached. The 4-Runner’s hard-rubber OEM bumper stops allowed almost 5-inches of upward rear suspension travel before “bottoming out” which occasionally caused the underhung spare tire or hitch drawbar to contact the ground in extreme off-road terrain -offs or sudden roadway dips when towing a loaded trailer. However, the SumoSprings worked magic because there was only ½” clearance between them and the rear axle housing under normal conditions, and the rear axle housing gently touched the SumoSprings when the trailer was hooked up – which almost completely eliminated rear-end squat on a sharp off-road -off or sudden roadway dip without making the 4-Runner ride like a hay-wagon, farm tractor, 1950 International pickup with overload springs, Jeep Wrangler, etc. in the process. After another 250,000 miles or so, I’ll put SumoSprings on my next 4-Runner – good show guys!!!

Way faster delivery than I expected. The Sumo Springs are great
by: Peter08/17/2023
These make all the difference towing a camper with my 4Runner. The rear sagged badly prior to installing sumo springs. Excellent investment. I was able to install them without removing the wheels, but the limited workspace made it challenging. Would be a piece of cake with the wheels off.

Remarkably easy to install and nearly eliminated all the squat on my 4Runner while towing. Provided more confidence in an evasive swerve I was forced into as well. I’m very happy I have them.

Fairly easy to install on GX 460 and does not change the unloaded ride quality. I installed without jacking it up or taking off the tire, but it was cramped space.
by: Don P04/14/2023
2017 Toyota 4Runner
I just returned from my first trip since installing the Sumo Springs on my 2022 Toyota 4 Runner and the improvement while towing my 3200 lb travel trailer was amazing. The squat was non existent and the overall handling felt more confident. The installation was easy, but I do recommend removing the wheel. This was a simple fix that works!
by: David 07/26/2023
Leveled up my tow vehicle nicely. Softened up a little bit overtime which makes the empty ride more comfortable over speed bumps.

Quick delivery, easy install, works as described
by: Dwight 11/06/2021
2010 Lexus GX 460
Better overall ride quality than the Timbren rubber springs I originally had installed. The Timbren are excellent for heavy loads and I may hang on to them for that reason. The Sumosprings were even easier to install than the Timbrens, so I'd recommend the Sumosprings over the Timbrens based on ease of install as well. It would make it easy should you find yourself needing to switch back and forth. It'll take you 20 minutes at the most to change both sides. This includs getting out the tools, jack, jack stands, wheel chocks,and putting everything away when done. Time is about the same with or without removing the wheels.
My GX460 is self leveling, but it doesn't hurt to give the suspension a little help towards longevity (Air bag repair can be pricey on the GX). Picture shows the limited work space with the tire on the vehicle while on the ground. Please note that with the vehicle raised there's a lot more room to work and access from the bottom as well. I didn't find the need to work from underneath the truck.

Hi this is Brandon Gager I ordered the sumo spring. Was there supposed to be a blue one & a black or driver & passenger side
by: Justin 07/07/2022
2010 Toyota 4Runner
This worked perfectly for what I needed my 4Runner no longer sags with the trailer and without the trailer it actually corners tighter with less sway and ride smoother.
And this directly mounted in the exact bump stop location with the same mounting hardware in fact they sent hardware I guess so it fit on other vehicles but it was a direct replacement of The bump stop on my 2010 4Runner

Can’t beat the Sumo Spring fir the price! Stabilized my 4 Runner body roll and kept it from sagging when towing my boat. In my opinion, these are a no brainer.

So far, so good. Much more support than the OEM bumpers. Hopefully they will last.

- Will SumoSprings Solo Springs Work With Toyota's Kinetic Dynamic Suspension System? Nope! The SumoSprings Solo Custom Helper Springs - Rear Axle # SS68DR you're looking at are going to work with all models of the 2019 Toyota 4Runner, so it'll work just fine with the KDSS option. These springs at 50 percent, have a 1,400-lbs capacity, has a simple no-drill install, and is made in the USA.
view full answer... - Can 2004 Toyota Sequoia Limited Carry Motorcycle CarrierI would recommend verifying with Toyota or your owners manual but it appears your 2004 Toyota Sequoia has a tongue weight capacity that would be able to handle the weight of your motorcycle and carrier as-is. A new hitch wouldn't be needed. I would recommend going with some additional suspension support which for that you'd want the SumoSprings kit part # SS68DR which can provide an additional 1,400 lb of suspension support.

These helper springs are going to help keep your 4Runner level when towing, help absorb bumps, shocks and minimize sway. They also have a no-drill installation and are maintenance free with no tubing to run or air pressure to monitor.
view full answer... - Is It Normal For SumoSprings Helper Springs On 2019 Toyota 4Runner To Touch Axle Under Light Loads? Yes, it is normal for the SumoSprings Solo Custom Helper Springs # SS68DR for your 2019 Toyota 4Runner to rest on the axle pads with some extra weight on the suspension. These springs were designed with no weight to just sit above the axle. As these springs are much softer than other suspensions such as Timbren they do not require as much clearance since they will not drastically diminish the ride quality.

These are a light capacity helper spring, and if you are off-road without a load in the back, you will feel them engage, but it won't be extremely jarring. With normal driving, however, short of going over a speed bump or pothole or really bad roads, there won't be an issue of these springs affecting your...

SumoSprings also have a minimal impact on unloaded ride quality so you won't notice a difference when you aren't towing. They have a no-drill installation and come with a limited lifetime warranty.

These won't affect your daily drive but will offer the support you need when you are going Overlanding. If you were only using your 2018 Toyota 4Runner as a daily driver I'd say stick with the 1,400 lb kit since there isn't really a need for the extra support.

Not only will the SumoSprings prevent sag from the tongue weight of your travel trailer being applied to the rear suspension of your 4Runner, it'll also minimize sway and body roll in turns.

As this fits into the rear coil springs on your 4Runner there is no need for any spacers. If you off road your 4Runner I recommend going with the SumoSprings Solo Custom Helper Springs # SS68DR.

There currently is no way of using a weight distribution hitch with the Lock N Roll hitch you have.

Thank you for the detailed feedback. When the SumoSpring is installed you will want to position the bracket so that it is offset outboard towards the wheel. This product does have a limited lifetime warranty against defects.
