When towing or hauling, rear sag can throw off steering and braking. These SumoSprings Solo Custom Helper Springs add up to 1,800 lbs of support at 50-percent compression to keep your ride level and steady. They help your factory suspension handle weight by compressing up to 80 percent under heavy loads, which keeps your tires planted and your headlights aimed right where they should be.

Every bump and dip doesn’t have to feel harsh. The microcellular urethane springs compress easily for lighter loads and firm up automatically as weight increases. That progressive load control means a softer ride when you’re empty and solid support when you’re loaded down. It cushions shocks, reduces bounce, and makes long drives with trailers or bed cargo a lot more comfortable.
When uneven loads or sharp turns want to throw you off balance, each spring works on its own to keep both sides stable. This independent action helps cut down body roll and sway so your vehicle feels planted through turns, crosswinds, or uneven driveways.
Built from tough closed-cell urethane, these springs resist abrasion, oils, road salt, and UV rays while performing in temperatures from -25 F to 200 F. They compress vertically with minimal side expansion so they won’t rub nearby parts or wear unevenly. And since they’re maintenance-free with no air lines or pressure adjustments to worry about, you just bolt them on and go.
Installing extra suspension support doesn’t have to be complicated. These jounce-style springs are custom fit for a straightforward, no-drill installation using basic tools. You get reliable rear suspension enhancement without running tubing or managing air systems—just solid support that’s ready to work every time you load up.

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this SumoSprings Solo Custom Helper Springs set. This is gonna help improve your driver control and comfort by upgrading the rear suspension on your 2016 and newer Nissan Frontier or Toyota Tacoma. This is going to replace your factory bump stops. It's gonna help to absorb bumps and shocks and minimize your sway to help keep your vehicle level as you're towing or hauling a heavy load. Now, most people are familiar when you're talking about suspension enhancement, they think of airbags and obviously these are not airbags, so there's gonna be some benefits and some drawbacks when you compare the two, but one major difference is that these are going to be very minimal maintenance, really no maintenance at all.
So, with your airbags, you're gonna have to add air. If you have a heavier load, let air out, so it's not too firm if you have a light load. Now, these are going to be constructed of a durable microcellular urethane. So, you're not gonna have to worry about airing them up or letting the air out. They work on a progressive load control design, so the springs compress according to the weight of your cargo.
So, for your lighter loads, the springs will compress easily to give you a nice soft engagement and a less bumpy ride. For your heavier loads, the springs are gonna compress by as much as 80% to support your load. These will have a weight capacity of 1,800 pounds. Keep in mind, that's not gonna increase your vehicle's weight carrying capacity. It's very tempting to think that that 1,800 pounds means that you're gonna be able to carry 1,800 pounds more in your truck, but think of it less like a second set of hands that's helping you lift more weight.
Think of it more like a back brace. So, it's there to help support your suspension system, take some of that strain off of it so it can last longer. Now, another major benefit to these is that it's gonna be very simple to get them installed. Basically, just fit right in place of your original bump stops. They do include instructions to walk you through that process step-by-step.
They also include a couple of different sizes of spacer here and the hardware that you'll need to accommodate those spacers to make sure that you have the proper spacing for your vehicle and these are custom fit brackets. So, again, you're not gonna have to do any drilling or anything like that. So, it's gonna be a very simple installation, as opposed to your airbags that will require you to run airlines and different things. So, it's much more involved installation, where this is gonna be very simple for you. Now, the one downside to these over your airbags is that they really are just kind of a set it and forget it sort of set up. So, you're not gonna have much control over how much support you're getting. So, with your airbags, if you want more support you can add air in, get a little bit more. These are just going to be what they are. So, you're not gonna be able to control them very much, but they are independent from each other. So, that's gonna help with your side-to-side movement. It's gonna help reduce your body roll and sway as you're taking turns and that sort of thing. So, they are gonna do a really good job for you without giving you that, whether you want to consider it a headache or a benefit of having to add air and take air out. These do have minimal lateral expansion, so they are going to compress vertically instead of off to the side. So, it's gonna help prevent any damage when you're operating in tight spaces. So, overall, really great option here to just kind of, again, improve your driver control and comfort. These are made here in the USA, so you can trust they are gonna be good quality and they also come with a limited lifetime warranty. So, if you we're to have any issues with them, you're more than welcome to reach out to us here at etrailer.com, but overall, a great way to help to support your suspension system, take some of that strain off of it, make sure it lasts for a nice long time. That completes our look for today, and again, I'm Michael with etrailer.com. Thanks for watching.

Glad to hear the install wasn't too bad, Michael! Definitely let us know how the ride is once you take it out for a drive! What are you using your Van for? The tires look pretty beefy.

The springs are working exactly as expect. I have need up to the mountains numerous times and to Monerary to the Sea Otter bike fest. They have reduced the body roll and helped keep the truck stable on the mountain roads or when loaded down for camping. Im very pleased I added these Sumo Springs to my Tacoma.

Glad to hear they are helping, Cory! If you are feeling them going over speed bumps, I think taking one of the spacers out is a good idea. Especially if that is happening when you are unloaded. Speaking of which, what are you towing?

Hey John, thanks so much for the detailed response and photos. That really helps other folks on the page. I'm glad install went well and you're liking them! I have these sumosprings on my Nissan Titan and it's a huge upgrade for towing!

One of my favorite things to recommend Kevin, the feedback is always so great on what a difference they make! What are you mainly towing that needed the extra support?

Excellent, I also tow a 6x12 cargo trailer which the Sumos do a great job of maintaining a level ride. I also installed Sumos front and rear on my 32 Tiffin motorhome. It utilizes the Ford F53 chassis and I believe they compliment that chassis well. Im definitely a big Sumo fan.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?
