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.

2014 Toyota Tacoma
I installed these, this month, on 2 pickups. A 2005 Toyota Tacoma witha 6' bed so it properly supports a slide in bed camper built by Scout. The other pick up is a 2014 Ford F150 Super crew w/6' bed. These Sumo springs corrected the trailering issues I had with my rear end dipping or drooping evertime I hitched a large boat, my 18' utility trailer or even my 16' sled trailer. I installed these along with new rear shocks and now the truck rides level when loaded. Very very happy with the ride, yes it does bounce a tad more but I am fine with that part. The Tacoma bounces a bit more unloaded too but when the camper is in, ride is perfect and level. I would buy these again and are very easy to install.

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.

2019 Ford F-150
Very easy to install. I had zero issues and it took me about 20 minutes. Pictures shown are a 2019 F-150 with max trailer package and zero weight in the bed. Test drive with no weight in the bed made the ride feel smoother and the back end was noticeably more muted when going over bumpy roads. Typical behavior without the sumo springs would have been a much bouncier ride.

2019 Ford F-150
Easy install. 0 maintenance. Keeps my 19 f150 crew from sagging badly when I have a atv in the bed and a trailer on the hitch. Helps give a more controlled towing experience. Would purchase again.
The 1000lb were perfect for me. Ride quality unloaded or loaded is still great.
by: Jeff09/09/2022
On my previous truck I had airbags, which I replaced 1x due to leaking. In addition to extra effort when pulling my travel trailer I was looking for something more maintenance-free and found these SumoSprings. It only took a few minutes to install and I've used these SumoSprings throughout the summer and find them to be just what I was looking for, they're perfect for use with my trailer or when I have a heavier load in my truck - I highly recommend these.

Ford F-150
My F150 seemed to have super soft rear springs. After adding a topper, any payload made it squat. The Sumo Springs have really helped stop that from happening. I'd recommend them to anybody that ever plans on putting anything in/on the bed of their truck or towing a trailer. You get the performance of airbag overloads without having install an air compressor or plumbing.
by: Hunter 09/12/2022
Easy to install and makes a big difference in how the truck rides when pulling our 5th wheel trailer.
by: Trevor04/28/2022
Put these to the test shortly after install with 1in. Spacer on my 2-1/2in. Leveled 2020 F150 FX4. 20ft heavy duty dual axle trailer - on it,a Bobcat 4wd tractor, bucket, and leveling blade attached. Plus tools, sacks of topsoil and rock in bed of the truck and on trailer. Truck sagged a little off of level but handled it beautifully... Even on rough Louisiana roads! Definitely recommend these springs!

Ford Flex
Better than I thought. Ride just fine, I'm over an inch off the leaf springs. I run a load dis hitch and the sumo springs are for back up. It's the leaf spring flex and body roll in cournering I wanted to minimize. Works as I wanted and saves my springs and shocks.
by: William06/21/2018
I have had sumo springs on my last truck and love them. You get the performance of air lifts without the air compressor and plumbing. Very easy to install and maintenance free. eTrailer delivered exactly what I ordered in 2 days. Excellent service!

2018 Ford F-150
I installed these on my 2018 F150 4x4. I did not use the 1" spacer, unloaded I have 1.25" gap between the axle and the Sumo spring. Unloaded I can notice the firmer rear suspension when hitting large bumps, but I can't tell a difference on small bumps. When towing a trailer this helped a lot to reduce the bouncing up and down in the rear that I used to get. I feel more in control when towing with these and I'm happy with them.

I used the 1000lb Sumo spring in a 2020 f150. They work great for hauling a camper. They don't destroy the ride quality like a Timbren (I previously had these in the same truck)

2019 Ford F-150
I have just installed the springs on my 2019 Ford F150 FX4 & immediately noticed a difference in ride quality. I haven't pulled my trailer yet but expect less rear sag & improved handling. Excellent product for price, ease of installation & improved handling.
by: Jeffrey 05/27/2021
Seems to be made well, final fit is good, took a minute to figure out mounting due to this item must fit a wide range of application.

view full answer... - Comparing Blue Vs. Black SumoSprings for a 2017 Ford F-150The loaded tongue weight of the trailer will likely be over the 1,000 capacity of the blue SumpSprings part # SSR-117-40 so I recommend the black SumoSprings part # SSR-117-47 for a 2017 Ford F-150. The tongue weight capacity of the trailer (loaded) is the best way to choose between the two.

view full answer... - Recommended SumoSprings for a 2013 Ford F-150 4x4 With the 3.5L EcoBoost EngineFor your 2013 Ford F-150 4x4 with the 3.5L EcoBoost engine, I recommend using the SumoSprings Solo Custom Helper Springs part # SSR-117-47 which are rated for 1,500 lbs. The reason I recommend going with the 1,500 lb system over the 1,000 lb system (part # SSR-117-40) is because it's better to have too much capacity than not enough. The SumoSprings are also made of a much softer material than their counterpart, the Timbrens so they won't have that jolting feeling while you are unloaded...
view full answer... - Will Adding SuperSprings Suspension Enhancement Raise The Rear Of A 2016 Ford F-150When suspension enhancement like the # SSR-117-40 are used, they do not raise the back end of the truck. These only provide support when you carry heavier loads and help when you travel over roads where the suspension may bottom out. Installing these suspension enhancement kits will not increase the vehicle capacity and are designed to be used with a suspension system in good working order.
view full answer... - Rear Suspension Enhancement Product for 2019 Ford F-150If your weight distribution system is set up properly, and you're using the correct system whose capacity can handle the fully loaded tongue weight of your trailer, you shouldn't still have a much of a problem with the rear suspension sagging. Before purchasing a rear suspension product, I'd recommend consulting the installation instructions and revisiting the setup procedure for the weight distribution system you're using to ensure that everything's been set up properly. I'd also recommend...
view full answer... - Will Adding SumoSpring Rear Helper Springs Create a Bouncier Ride on Unloaded 2014 Ford F-150If you take a look at the instructions I have linked for SumoSprings # SSR-117-40 you will see that, when unloaded, the springs make little to no contact with the rear axle on a 2014 Ford F-150. If may seem a little more stiff when going over bumps. So it will have a small effect on the unloaded ride quality.
view full answer... - Best Suspension Enhancement for 2018 Ford F-150 Towing TrailerThe best suspension enhancement solution we have for your 2018 Ford F-150 4x4 that you'll be towing with is the RoadActive Suspension Kit part # RAS3611-YHD which is easy to install, adjustable in support, maintenance-free, and unlike other options actually improves ride quality loaded and unloaded whereas other options are known to make the ride rougher.

They offer a bolt-on fit and work well to reduce sag while towing or hauling. The 1,000 lbs of support they provide will be more than enough for your setup. Just make sure the tongue weight of the trailer and weight of cargo in the bed over the rear axles does not exceed this rating.

The closest thing to SumoSprings I have, that will fit your vehicle, is the Timbren Rear Suspension Enhancement System part # TFR1504E. This fits the rear axle of your 2021 Ford F-150. They will help to reduce body roll and to provide additonal support when you need it. I have included...

The SumoSprings Solo Custom Helper Springs # SSR-117-40 are maintenance-free and have a 1,000 pound capacity and will upgrade your Ford F-150's rear suspension system. The springs have a simple, no-drill installation and work in temperatures from -25 F to 200 F. I attached a review video link below.

In regards to the SumoSprings, you will always want to have a safety margin and the above will be perfect for your setup. The springs have a progressive load rate so the 1,500 model with 850+ lbs will have a smoother ride than the 1,000 lb model with 850+ lbs.
