Specs:
A heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear 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 front 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 rear 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.

2,800-lb Capacity. Upgrade your vehicle's front 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.when I received these front springs ( The rear are on back-order until freak'n March) having never used these things, the instructions say "take them apart" nowhere does it say "to get them apart, TWIST the adaptor plate off" ~~~ I guess Im not smart enough to figure THAT out. Installation looks super simple, when I get the stern springs installed, in a month, I'll write another, more detailed review. But for those who have never encountered this product, when you get them, TWIST (unscrew) the adaptor plate
Just got the sumosprings put on my 2017 f250, took it for a short drive the ride seemed better then it was with the factory bump stops. I also put on a set of timbern super duty bump stops earlier. I really like this product, truck rides nice and doesn’t sag when I hookup to my 14000 pd catering trailer when fully loaded. Both products well definitely make my truck ride better.
I love these Sumo “springs”. eTrailer never disappoints me. I had Stoops in Lafayette Indiana install them for me. I knew when I left the parking lot I was going to like them. Side to side sway is gone. Potholes are a slight bit harsher but is a small price to pay for the MUCH better handling I now have.
ordered the wrong size initially but after talking to a rep from SumoSprings and realizing my mistake I was able to exchange them for the appropriate size for my needs. Customer service was excellent, and they make a huge difference with the plow on without serious effects to the ride.
Extremely easy install! You will definitely have to have a floor Jack, there is no muscling the spring in without raising the frame.
Great price. Fast shipping
These are amazing! Softened the harsh ride substantially. Wish I'd found out about these earlier....
Excellent product, really helps to stop roll in the rv body
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.

Very straight forward installation. Simple. very noticeable difference under load. Towing with the gooseneck also an improvement, looking forward to the longer road trip test. So far pleased with the product and results
Review from a similar SumoSprings Solo in Vehicle Suspension
Parts arrived on schedule. At first I thought that the parts did not fit my truck, so I called customer service and they immediately started to send me a return label and refund. It turned out that I was wrong, and the parts did fit. I called them back cancelled the refund action.
Great friendly service!
I also found that the price I paid was much cheaper than [online store]. I highly recommend etrailer!
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.

I have always used airbags in the past and this is my 1st time using SumoSprings and I can say I will never go back to airbags! I run a heavy load on a 21’ 4Runner pulling a Teardrop with two motorcycles on stock suspension

I am happy doing bussines with Etrailer, I ordered the wrong Super springs for my Ram Promaster 2500 by mistake, called them up spoke to miss Paula and she was able to find and ship the correct one fot my Vehicle within a couple of days. She even send me a Return lable so I can return the other one back to the company. I look forward to continue doing bussines with this company.

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
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.
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.

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.

Senior citizen Installed in 30 mins on a 2022 f250 that hauls a 5th wheel. If I can do it must be an easy install. Use only one 1/2” spacer. Will test out in the coming weeks.
