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.

Ford F-250 Super Duty

They do a good job at supporting the the rear end of my F250 for towing my travel trailer. More affordable and simpler to install than air bags. I also installed the EZ lift springs. They work great together.

Working Great
David F - 07/28/2022


Installation took about half an hour. The fifth wheel with a gvw of 15000# used to sink the truck box significantly. After installing the Sumo Springs there is a minimal sinking of the truck. I highly recommend!

2016 Ford F-250 Super Duty

Excellent product. Delivered on time. Very easy install. My '16 F250 squatted slightly with my camper on, sunk 2" at the factory jounce bumpers, and slightly swayed on curves. Problem solved. You may only need to slightly lift the truck by putting a car jack under the hitch, as I did. I only needed to raise mine 3-4" and no need to remove wheels. Also, it is easy to reattach the factory bumpers to a harmless location under the frame. So, if you sell your truck in the future you can easily find and reinstall the originals....and keep the Sumos for your next truck....if they fit.


Great product, definitely gets my truck leveled out with our 5th wheel trailer! Easy to install, would highly recommend Sumo Springs.

I would highly recommend etrailer, there customer service unsurpassed, great products, great company!

2015 Ford F-250 Super Duty

This is probably the best thing I could have done for my truck. The install was easy. Without these, the truck would drop 3 1/2 inches in the back with the RV on. Now only one inch. The truck is a 2015 F-250.

After a year of use, Im very happy with the Sumo springs. Much better ride and nobody flashes their hi beams at me anymore because the truck rides nearly level even with the weight of the 5th wheel on.

Ford F-250 Super Duty

Fast customer service. I easily install them on the rear of my two thousand five F-250 4x4 with factory overload springs. Since installing it is a much smoother ride when unloaded and now only squats about 1 1/2 inches when pulling 7500+ pound camper. The hardest part about installing these was removing the factory bump stops.

Ford F-250 Super Duty

I purchased the Sumo Springs due to rear end sag on my F-250. They pretty much fixed the problem which was caused by too-weak springs in the first place IMO. No change in the ride quality either loaded or unloaded detected. Prompt shipment & knowledgeable sales staff. Very helpful.

1998 Ford F-150

Customer service was very friendly,helpful,and professional. Receive my order on time. I Would strongly recommend your service to anyone who have the need for your products..


Etrailer was quick and accurate, shipping was fast! Highly recommend!


Don’t even notice they’re there, meaning when they’re engaged the ride is still smooth and not stiff




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.

They are working great in my 12 tundra still would recommend them. I tow 8000lbs camper handles great at times I probably wished I got the next step up but might be to hard when not towing. Will see next time I need to get some for next truck. Wish they have measurements to know how high they are from the lighter ones to the heavier ones.

Review from a similar SumoSprings Solo in Vehicle Suspension

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

after a year i could buy them again. great performance and no issues.

Review from a similar SumoSprings Solo in Vehicle Suspension

I had Sumo helper springs installed on my Winnebago Sprinter RV both front and back. It made an amazing difference! It no longer felt like riding in a Conestoga wagon…swaying side to side and bouncing everything to the floor. The ride is now smooth. Driving was easier. Turns are suddenly level instead of feeling like I might turn over. I could not be happier with these products! And it only took 20 minutes to install all four!

Review from a similar SumoSprings Solo in Vehicle Suspension

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!!!

Yellow for the super heavy load and daily driving I have the black middle weight springs. Easy swap out when I need the yellow Heavy Duty.

Review from a similar SumoSprings Solo in Vehicle Suspension

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.

Fantastic, the Sumo’s are working as promised. Helps with sag, smooths out the ride and provides support from sway. I couldn’t be more happy. This year we will be adding Sumo’s to the 5er to help in the back, super excited about this upgrade.

Review from a similar SumoSprings Solo in Vehicle Suspension

They help. My 2016 F250 feels more stable towing my 8500 pound travel trailer along with the EZ lift springs, plus Bilstein shocks.
A good combination upgrade I can afford and install myself in my driveway.


Review from a similar SumoSprings Solo in Vehicle Suspension

I installed these myself on a 2020 F150 XLT 4x4 in half an hour. There was no need for a jack or jack stands because the ride height of the stock suspension allowed just enough room. As you can see in the photos, the assembly is about 9” tall, the same distance between the frame and the axle. The ride height remained the same as before using the 1” spacer! The instructions did fail to mention that a 15mm socket is needed to tighten the new hardware.

I do have a concern about the shape of the spring at the axle being unlike the oem bump stop. Why couldn’t the spring have the same contour so that deflection would be minimized? I say this because of the very close proximity of the brake lines and wiring harness to the helper spring, especially on the driver’s side. It would be interesting to film the movement of the helper spring as this vehicle is driven over rough roads to see just how close it comes to the brake lines. I’m not completely satisfied in the design, so we’ll see how this goes.


Review from a similar SumoSprings Solo in Vehicle Suspension

The SumoSprings Helper springs have too much clearance between the spring and the axle. Probably because I have helper springs on the rear axle which raises the Sprinter somewhat.


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!

The springs still work as they should. They are nice because they dont seem to affect the ride quality when the camper is not on the truck. Very happy with my purchase.

Review from a similar SumoSprings Solo in Vehicle Suspension

Made towing TT with my Toyota Tundra much better. My camper has a tongue weight over 900 pounds. Made bridge crossing and overpasses much smoother.


Review from a similar SumoSprings Solo in Vehicle Suspension

The massive ride feel improvement, I have a topper and drawers in the rear of my Tacoma. With the SumoSprings and medium-duty Old Man Emu leaf springs, the truck does not feel any hint of bucking or kicking anymore.


Review from a similar SumoSprings Solo in Vehicle Suspension

As advertised very easy to install these Sumo Springs on my 21GMC 1500. I only installed the plate not the 1” spacer. I tow an RV and expect the ride to be more balanced and able to carry more “stuff”. Ride after install is still smooth but on larger bumps I can notice stiffness. Very satisfied right now


Review from a similar SumoSprings Solo in Vehicle Suspension

The sumo springs have been a very good addition to my Toyota Tacoma DCLB. I added a leaf and changed the shocks at the same time I added the sumo and the truck rides about a half inch above the sumo. I definitely can feel the sumo kick in when I compress the rear on bumps etc. non loaded. It’s not a bad thing but I don’t get the same travel but I also don’t slam on the bump stop. With that said, both driving with a loaded up truck and trailering has been much better than before. I can definitely tell the sumo doing its job. I towed a 4000lb boat the other day and the truck behaved perfectly.

  • SumoSprings Suspension System Recommendation for 2000 Ford F-250 4x4
    I tend to recommend people go with the lighter duty SumoSprings since they will give the best ride quality loaded and unloaded. They still will give you the support you need but not at the cost of a decent ride. So I would recommend the # SSR-114-47 for your 2000 F-250 since it will give you 1,500 additional lbs of support.
