Rear Suspension Support

SumoSprings helper springs are great for pickup trucks. Towing or hauling a heavy load can cause 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 truck's weight. 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 factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.

The innovative 2-piece design of these Rebel springs allows for unlimited suspension travel. This means that there will be more movement in your suspension when you're unloaded or off-roading, which makes your ride smoother and more comfortable.


Each spring has 2 pieces. One piece attaches to the frame of your vehicle. And the other piece attaches to the axle, typically above your existing factory leaf spring. The pieces come together to provide support when you are towing or hauling a heavy load. When you're unloaded, they separate so that they don't restrict the movement of your suspension. The closed-cell urethane springs also act like a shock absorber to dampen road vibration.


SumoSprings compressing under load

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 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 expand and 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.


This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

Video Transcript for All You Need to Know About the SumoSprings Rebel Custom Helper Springs

Ellen: Hey, everybody. I'm Ellen here at etrailer.com, and we're going to be taking a quick look at the SumoSprings Custom Helper Springs for the rear axle of your vehicle. Now, these are going to be a really great solution to alleviate a lot of issues that people have whenever they're towing anything heavy with their vehicle, putting maybe a trailer on the back of your truck, a fifth wheel, or pulling a camper behind with a hitch ball. What these are going to do is they're going to help to support your suspension. They're going to give you some better handling overall, and they come in two parts.So unlike airbags that are going to do similar things, these aren't going to hamper the travel of your suspension. That can be kind of one of the drawbacks to getting an air suspension or airbags in your vehicle.

Not only that, but they also require a lot of maintenance to keep them up. So these are pretty much maintenance free. Once you put them in your truck, you don't have to ever worry about them again. They're just there. They do their job.

But what they will do is they have a progressive compression. So the more weight you put on them, the stiffer they get to push back against that. So it kind of dials it in for your load. So you don't have to worry about it being too stiff. If you're just going down the road and hitting a normal pothole or anything like that and not towing, it shouldn't be a really stiff or fast engaging type of feel.This also makes it easier for whenever you're getting any kind of maintenance done on your vehicle.

So that's another drawback to airbags is that sometimes if you are getting maintenance done, your suspension needs to hang and that can actually damage the bags. So you don't have to worry with this. They already come separate on their own. So they're a really easy way to alleviate a lot of issues with body roll or rough ride on your vehicle while you're trying to tow.So let's look at them a little closer and talk about what comes in the kit. You're going to get a spring for either side.

And, again, this is for the rear axle of your vehicle. There'll be an axle strap that's going to go around that and then the hardware to get everything installed. So there's no cutting or drilling required with this. It just goes right in place and should be a pretty easy install. Might take a little bit of time to just kind of get in to the spot and get everything in place where it needs to go.The springs themselves are made out of a micro cellular urethane. So that's really durable. It's able to withstand any kind of damage from oils road salts, UV rays, it really doesn't cause any issues with these guys. They're able to work from extreme temperatures of negative 25 degrees Fahrenheit up to 200 degrees Fahrenheit. So it really doesn't matter where you're using these, they should be up to the task for that. Also, something that's nice about these is that there's not a lot of lateral expansion, so they're not going to pancake out. They should stay relatively compact. So even as things are pushing down on them, they're not going to cause any issues with your existing suspension or with your wheels and rub on anything.There's also, again, no worries about any kind of maintenance. You don't have to run any air tubes to these and worry about those. So even if you're going to be going off road with these, you can rest assured that they're not going to hamper how far your suspension can travel. Just going to be these two pieces that bolt on, kind of as a replacement for your jounce bumpers, so they are a jounce style spring, and they are made in the USA. This is a fit for the 2011 through the 2016 Ford F 250 and F 350 Super Duty and for the 2014 through '16, that's for the two-wheel drive.Now, if you want to get a kit for these, that would be matching for the front, you can also find that here at etrailer.com. That would be one that would fit those same year models as well. So that'll kind of alleviate some of the other issues that you might be having. The weight capacity that these can take at 50% compression is 3,000 pounds. That does not increase your overall weight carrying capacity, so keep that in mind. It doesn't increase your payload or anything in your vehicle. So you always want to go off of the manufacturer's recommended weight and never exceed that. They are covered by a limited lifetime warranty.And that's really about all there is to it for our look at the SumoSprings Rebel Helper Springs. I hope this video has been helpful in deciding if this is the right solution for you. We do have a lot of other accessories here for towing and all kinds of stuff. So check it out. Thanks for watching.

  • Recommended Helper Spring System for Gooseneck Hitch Equipped 2014 Ford F250
    Your best helper spring option will depend on what all you use your truck for. If the primary use is towing a 5th wheel, I'd honestly go with something like the SumoSprings # SSR-139-40-2 for 4WD trucks or # SS29MR for 2WD trucks. The SumoSprings product offers 3000 lbs of additional support and is ideal for gooseneck or 5th wheel towing situations where the weight applied to the rear suspension doesn't vary much. The SumoSprings won't affect your ride quality until a load applied to...
