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.

Video Transcript for An In-Depth Look at the SumoSprings Solo Custom Helper Springs-SS38DR

Hi, everybody, Andy here with etrailer.com. Let's take a look at the SumoSprings rear axle solo custom helper springs. Now, these springs are designed to fit your 2010 and newer Isuzu N-Series. And on custom-fit parts such as these springs, I do recommend taking advantage of our vehicle fit guide. Simply input the year, make, and model of your vehicle and our fit guide will confirm if these will work for you, or if we have something comparable that will work for you. So as you know, 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 the front of your axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. So these SumoSprings are gonna upgrade your vehicle's factory suspension to level your vehicle, improving the driving performance, and keeping your ride comfortable. These 2,800 pound capacity helper springs 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. And the closed cell urethane material allows for a smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration. Now, these springs can compress by as much as 80% to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which is going to level your vehicle and ensure that your front tires are making better contact with the road.

So a level ride means that you have improved driving control, it ensures safe head lighting, and it helps to minimize sway. The springs also supports your factory suspension, which helps prevent sagging, and it's gonna reduce that bottoming out. These springs are gonna 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, and this also helps compensate for an off center load. So these microcellular urethane springs are tough, they're gonna resist abrasion oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from negative 25 degrees Fahrenheit, all the way up to 200 degrees Fahrenheit.

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. These jounce-style springs are made here in the USA. And again, they are custom-designed to fit your Isuzu N-Series. Again, 2010 and newer, and they are going to install very easily. What's nice about these No drilling is required and it does include the hardware, which I have loosely attached here as well as these one-inch spacers. So you're gonna have everything that you need to install these. Easy install instructions are included to guide you through that installation process. And the weight capacity at 50% compression, again, is 2,800 pounds. But I do wanna point out that SumoSprings do not actually increase your vehicle's weight carrying capacity. So you wanna make sure that you're not exceeding the manufacturer's recommended weight limit. These do have a limited lifetime warranty. And that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
