1,400-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
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.
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.

1,400-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.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!.
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.
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.
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.
The SumoSprings were in stock, shipped on-time and were received in good condition. The installtion instructions were excellent, the install straighforward and I am so far completely happy with both the product and service.
Sumo Springs are one of the best investments you can make for your Tacoma or any lightweight pickup. They support your weight compliant trailer, travel trailer,and normal truck bed load much more safely. But best of all, your pickup will no longer sag down in the rear, which then allows the truck to evenly share the load you are hauling, and give you the safest, best handling, smoothest ride you can imagine, putting more of the load up front. Your tires will grip the road the way they are supposed to for a safe ride. No more dangerous swaying all over the road!!! Don’t forget to invest in a travel trailer sway bar hitch with your Sumo Springs. I’m a retired UPS driver. Almost daily I observed unsafe trailer setups with pickups and SUVS sagging down low in the rear; some nearly touching the pavement! Please. Think safety first. Truly enjoy your trailer, even your dump runs! Buy some Sumo Springs from etrailer. Check out the website at etrailer.com. I found it best to call them to pick the best set of Sumo Springs for your truck or SUV. Time to carry the load and hit the road safely with your rear mounted Sumo Springs from etrailer. Great prices too!!!
Worked well for me, as I normally carry about 200 lbs of tools and miscellaneous items in the bed. Before installation, I had a small amount of extra "bounce" from the rear that went away after installation of the Sumos. I also do some occasional towing of a 6X10 trailer, and the ride and handling were improved by the Sumos.
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. THANKS
I wanted a product that would lessen the harshness of bottoming out on the factory bumpstops when loaded, but not affect the ride quality when the truck was empty. These seem to be meeting both of those criteria perfectly. Installation was straight forward, took about 20 minutes with a 19 mm socket, 1/2" ratchet, and 1/2" torque wrench for final 52 ft lbs, on my 2017 Tacoma TRD Offroad. My typical "loaded" combined cargo/passenger weight is 700 - 800 pounds. I wasn't sure if these would be heavy duty enough, or if I should get the 1000# SSR-612-47 sumos. Glad I went with the 500# SSR-612-40.
Way to bouncy. I drove around the block and took them off.
These work out great on the Tacoma, while towing my snowmobile Trailer. It keeps the truck from sagging in the rear from the tongue weight of the trailer. Also works great when loading the bed ect. Doesn't seem to effect ride when there's nothing in the Bed.
Awesome product,It work out great to my 2018 Tacoma.Excellent service From etrailer.thanks
It arrived when expected, was easy to install and seems to have done the job. We haven't taken it on the road yet and not sure when we will but it looks good.
Very happy with purchase
Review from a similar SumoSprings Solo in Vehicle Suspension
I would have give it a 5star but the bolts are 1/4” I think it should be at least minimum of 3/8” or1/2” bolts to hold the sumo springs. I like them toed the camper handles very well. Wishi got these a long time ago worth getting. With out camper can tell that it’s there but rides ok. I wanted the same ride it not quite. I ask what the how high they are said 5” with bracket but it’s actually 6” with bracket see picture. I would recommend getting the sumo springs ssr-610-47.

2015 Frontier Crew cab Desert Runner (purchased the yellow Sumo Springs). Easiest install ever! 18mm deep socket and long breaker bar for breaking nuts loose. Removed factory bumpstop, install sumo bracket and retighten U bolts to 58 foot pounds. After installing both brackets, lifted back of truck up 4 inches to install sumo spring with blue lock tight on bracket bolt, tighten sumo spring onto bracket and lowered truck off the jack. Overall it raised the back of my truck bed 1 inch. Ride is stiffer with no bed roll in the turns. Loaded my 24 foot travel trailer with load leveler- equalizer bars and gained 3 inches (less “squat”.) Truck is level now vs nose high (without the sumo springs). Definitely an upgrade that was needed in 2015 when I first bought the truck!!!

I just finished installing the Sumo Springs to my 2020 Ram 3500. The install was super easy. Instruction were easy to follow and the whole thing took less time than I thought. I won’t know how they perform until I pull the 5er out of storage this spring, but I am ready. My only question and the reason for 4 stars instead of 5 was I thought they would sit closer to the axle than they did, may 2” from axle and I would have liked may 1” maybe I could have used another spacer and longer flat head screw to bring it closer but we will see when I put the weight on the truck. I included picks if someone wants to give me their opinion. So far I am really happy with them.
Review from a similar SumoSprings Solo in Vehicle Suspension
We pull an off-road teardrop camper with our 2013 Toyota Tacoma and were looking for a little help with the rear end sag when we have that hitched plus putting some weight in the back of the truck (firewood, water, etc). Our Tacoma is lifted (2.5") but the lift kept the stock springs with an added Deaver leaf to help with the notoriously soft Toyota springs. However, with the shell and ~300 pounds of weight in the back, it still sagged, especially with another 250 lbs of tongue weight from the trailer. The Sumos have eliminated that sag, even with bigger loads in the bed, eliminated body roll (also notoriously bad with Tacomas) and didn't destroy the ride for day to day driving. There might be a slight bit more stiffness when hitting speed bumps, but definitely not bad at all. If anything, I would say it IMPROVED the ride and handling. The springs themselves were simple to install, less than half an hour start to finish. Some reviews have said they were bumping the frame after installing but we had about 1/2" gap on both sides. The only "specialty" tool would be a torque wrench capable of 90 lbs to get it to spec. We considered Firestone air bags but after talking with the reps at e-trailer, we decided on these and couldn't be happier. Reasonably priced (half the price of air bags), no maintenance, great customer service...can't argue with anything at all.

2007 Workhorse W22 chassis, easy install, slight KJ knuckle busting on drivers side, but patience works.
Review from a similar SumoSprings Solo in Vehicle Suspension
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.
Review from a similar SumoSprings Solo in Vehicle Suspension
Instructions were adequate. installer has to contribute to the outcome with bolt cleaning, match marking axle saddle and finding out "u" bolt torque value. I think the mount should be radiused where the "u" bolt contacts it as opposed to the square edge. Was unnecessary to jack up truck to get clearance to screw on spring, I put a wood between frame and leaf and raised the box 1/2" with a wedge. I got the ride height I was looking for, the blue springs are very close to offsetting trailer tounge weight allowing for a bit of takeup with my Andersen hitch. Barely noticeable change in unloaded rear end stiffness.

When installing the springs I discovered that one of the mounting plates (1 out of 4) had 2 of the holes missed drilled and was unable to install. I had to send back to etrailer.
