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.

  • Towing Capacity and Recommended Upgrades for 2017 Ford F-250 to Pull 5th Wheel Trailer
    The first thing I recommend doing is simply making sure that your 2017 Ford F-250 has the towing capacity needed to pull the Grand Design Solitude 373FB Trailer. There are a variety of aftermarket components that will allow the truck to operate better and easier within its towing limits, but nothing that can actually increase the towing capacity set by the Ford. Based on my research the Grand Design Solitude 373FB has a GVWR of 16,800 pounds. This is the most it can weigh when fully loaded....

  • Comparing SumoSpring Options for 2020 Ford F-350 Towing a 5th Wheel Trailer
    Really the only difference is that the SumoSprings # SSR-127-47 have a 1,500 lb weight capacity while the SumoSprings # SSR-127-54 have a weight capacity of 2,800 lbs. So one just offers more support for your 2020 Ford F-350 and would offer better performance for heavier loads. Since your 5th wheel has a pin weight of about 2,500 lbs I recommend going with the kit # SSR-127-54 so that this can help with all of the pin weight. It's important to note that all suspension enhancement systems...

  • SumoSprings for 2023 Ford F-250 Towing Winnebago Voyage
    Hi Tim; the yellow SumoSprings # SSR-127-54 will be able to handle that weight but it sounds like you will be really close to their limit. Between the tongue weight, truck bed weight, and the long distance towing I think you would be better off adding the SumoSprings Rebel Custom Helper Springs # SSR-128-47-2. These have a higher 5,000 lb capacity which would be better for your application. They also have a 2 piece design which gives a smoother ride when you aren't towing or hauling....

  • How To Determine The Correct Capacity SumoSpring For A 2022 Ford F-250
    Suspension enhancements don't increase the capacity of the suspension and are typically chosen based on the load that the truck will be handling. Too high of a capacity tends to give you a rough ride quality when unloaded because the enhancement is too stiff. Too low of a capacity and you'll have sag, uneven wear on your suspension, and bad handling. SumoSprings offer a much softer progression so they're one of the best options to handle the load and still give you a good unloaded ride...

    Here is a list of the bump stop replacements we have which fit your 2024 Ford F-350. If you can tell me how you plan to use your F-350 I can give you my personal recommendation for the option which works best for you.

  • Best Suspension enhancement Kit Recommendation for 2024 Ford F-250
    The best suspension enhancement kit we offer for your 2024 Ford F-250 is the SumoSprings kit part # SSR-127-54 which will give you the best suspension support to prevent sagging and also not make the ride quality overly harsh.

  • Recommended Suspension Enhancement For A 2022 Ford F-350 Dually
    I can certainly point you in the right direction. I agree with you that the 2,800 sumo springs # SSR-127-54 will not be enough for the kind of weight you are pulling with your 2022 Ford F-350. They may help slightly with sagging, but you would be overloading the springs and that is never recommended. A Timbren # TFR350SDJ would be much more appropriate for this application. These are 8,600 lb capacity rubber springs which will absolutely help eliminate sagging, and improve your ride quality...

  • Are Timbren or SumoSprings a Better Option For a 2024 Ford F-250 Super Duty?
    Personally I feel the SumoSprings Solo Custom Helper Springs # SSR-127-54 are a better option for more users on a 2024 Ford F-250 than the Timbren # TFR250SDJ. The SumoSprings are more more progressive and will provide a better ride quality when unloaded or only carrying light loads. I only recommend going with the Timbren springs when you always carry heavy loads such as replacing your bed with a contractor box loaded with tools.

  • SumoSprings Suspension Kit Recommendation for 2024 Ford F-250
    For your 2024 Ford F-250 you would want the SumoSprings kit part # SSR-127-54 which is a confirmed fit that can give you an additional 2,800 lbs of suspension support. It will give you a great blend of support and ride quality that will get rid of suspension sag while also not giving you a harsh ride quality.

  • Recommended SumoSpring for 2022 Ford F-350
    I suggest the SumoSprings Solo Custom Helper Springs, # SSR-127-47 if you will be using this to tow but also as a daily driver. This is the better option to provide maintenance-free helper springs and still provide the factory comfortable drive when not loaded. These have a 1,500 lb. weight capacity while the SumoSprings, # SSR-127-54 have a weight capacity of 2,800 lbs. The SumoSprings Solo Custom Helper Springs, # SSR-127-47 compress according to the weight of your load. The sturdy...

  • Comparing The Solo And Rebel SumoSprings Options For 2022 Ford F-350 Super Duty
    Between the SumoSprings Solo Custom Helper Springs # SSR-127-54 and the SumoSprings Rebel Custom Helper Springs # SSR-128-40-2, I do prefer the Rebel. The Rebel's 2 piece design allows for better compression and movement with the axle, giving you a better and more comfortable ride. The higher capacity, though pretty small, does also lend itself towards more heavy duty trucks, like your 2022 Ford F-350. This means they will suit your needs better and will be the better option. I also like...

  • What are the Best Rear Sumo Springs for my 2016 Ford F-250?
    For your 2020 Ford F-250 Super Duty there are two SumoSprings options that fit your truck like you mentioned. There's the 2,800 lb kit part # SSR-127-54 and the 1,500 lb kit part # SSR-127-47. Basically you want to go with the lightest duty kit that will work for your application. Going heavier than you need will give you a harsher ride quality than you'll want loaded and unloaded. You didn't mention the pin or tongue weight of your trailer, but unless you are at the max capacity of around...

The Sumo Springs Solo Custom Helper Springs - Rear Axle # SSR-127-54 are made of a durable, high-density microcellular urethane and have a 2,800 lbs weight capacity, though they will not increase your vehicle's weight-carrying capacity.

  • Recommendation of Suspension Enhancement for 2022 Ford F-350 Super Duty With Truck Camper
    For your application where the truck will be under constant load, jounce-style springs are a good option. I recommend going with the higher rated SumoSprings, # SSR-127-54. These have a 2,800 pound capacity and will do a really great job of bringing the truck back to level and smoothing out your overall ride. This is a simple no-drill installation and once they are in place you don't need to worry about performing any maintenance or making any adjustments to the springs.

  • How To Pick Out SumoSprings Suspension Enhancement For 2020 Ford F-250
    Unless you are near or at maximum capacity for your truck tongue weight, it would make sense to use the lighter of the two, # SSR-127-47 instead of # SSR-127-54. This will provide you a smoother ride overall but especially when you're vehicle is not loaded. Either way the SumoSprings are a substantial upgrade from the factory bump stops, longer in design, and are more sturdy to absorb shock and progressively stiffen under loads.

  • What Are the Differences Between Sumo Springs Solo vs. Rebel?

Also, the design is a bit different. Where the Solo Custom Helper Springs are a one-piece design, the Rebel Springs are a two-piece design that is separated in the middle that allows for unlimited suspension travel. One piece attaches to the frame of the truck, and the other attaches to the...

  • Which SumoSprings Kit for 2020 Ford F-250 Towing Fifth Wheel Trailer
    The SumoSprings part # SSR-127-47 that you have now might be your best option but it depends on if you are happy with the amount of sag reduction it provides currently and the ride quality. It's a balancing act between support and ride quality so if you need more support I would go with the higher rated # SSR-127-54. You said the truck is sitting level now which most likely means it's sagging since the rear end of the truck probably sat up higher without pin weight on it. I would anticipate...

  • How Will the SumoSprings Helper Springs # SSR-127-54 Affect Ride Quality On 2018 Ford F-350 Unloaded
    With the SumoSprings Solo Custom Helper Springs # SSR-127-54 for your 2018 Ford F-350 you do get a 1" and 1/2" spacer. These spacers will allow you to increase or decrease the air gap between the axle and SumoSprings. The larger the air gap the less noticeable the springs will be on your ride quality when daily driving. When daily driving you may notice a slight increase in stiffness when hitting large bumps as your suspension is already going to be very stiff with a 1-ton truck unloaded....

  • Choosing Sumo Springs or Timbrens For 2020 Ford F-250 Towing 10,000 lb 5th Wheel
    You would indeed get a softer ride using the Sumo Springs # SSR-127-54 as opposed to the Timbren # TFR250SDJ. The Sumo Springs offer 2800 lbs of support versus the 8600 lbs offered by the Timbren springs. Given that the pin weight of your 5th wheel wouldn't be more than 2000 lbs, the Sumo Springs will be absolutely perfect, providing the proper amount of support with a better ride quality than what you experienced with the Timbrens.

For your application I recommend the part # SSR-127-54 if you only tow your 7K trailer occasionally or the Extra Heavy Duty # SSR-129-47-2 (2WD) or # SSR-128-47-2 (4WD) if you tow often enough that it is like a constant load.
