When the front end starts to sag under a heavy load, steering and braking can feel off. These SumoSprings Solo helper springs add up to 1,400 lbs of support at 50-percent compression to keep your front end level and steady. They help your factory suspension carry the extra weight so traction and control stay consistent, even with gear or equipment up front.
Rough roads and uneven loads don’t have to mean a harsh ride. These microcellular urethane springs use progressive load control—compressing easily at first for soft engagement with light loads, then firming up as weight increases. The result is smooth contact that cushions bumps and absorbs shock while keeping your ride comfortable no matter what you’re carrying.
When corners, crosswinds, or uneven ground try to throw you off balance, each spring works on its own to keep its side stable. That independent action helps reduce body roll and sway so your vehicle feels planted through turns and steady on the highway.
Built from tough microcellular urethane, these springs resist damage from oils, road salts, and UV rays, performing reliably in temperatures from -25 F to 200 F. They compress vertically with minimal side expansion to fit safely in tight spaces. And since there’s no air pressure to monitor or lines to run, they’re completely maintenance-free once installed.
These custom-fit jounce-style springs install easily without drilling. Once in place, they work alongside your factory suspension to level your ride, minimize sway, and prevent bottoming out—so you can load up with confidence and hit the road without extra hassle.

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at the SumoSprings Front Axle Solo Custom Helper Springs. Now, these are custom fit for the vehicles that you see there on your screen. I would recommend taking advantage of our Vehicle Fit Guide here at etrailer.com. Input the year, make, and model of your vehicle and our Fit Guide will let you know if these will work for you or if we have something comparable that will work for you.
So as you, no doubt, know, a heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. So what this means is that your front 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 rear axle, your rear tires make less contact with the road, which causes problems with traction, steering, and braking. So SumoSprings are gonna upgrade your vehicle's factory suspension to level your vehicle, improving drive performance and keeping your ride comfortable. These 1,400-pound capacity helper springs are going to provide progressive load control.
And what that means is the more you load them, the stiffer they become. With the lighter load, the springs will compress easily for soft engagement and a less bumpy ride. 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, the springs can compress by as much as 80% to support a heavy front load and to help your factory suspension bear up under that load. This is going to even out the weight, which levels your vehicle and ensures that your rear tires are making better contact with the road.
A level ride means that you have improved driving control, ensure safe head lighting, and it helps minimize sway. The springs also supports your factory suspension, which is going to help prevent sagging and reduce bottoming out. So the springs work independently from one another to support each side of your vehicle. This action helps reduce body roll when you make a sharp turn and this also helps compensate for off-center loads. Now, 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 and temperatures ranging from negative 25 degrees Fahrenheit all the way up to 200 degrees Fahrenheit. So these springs compress vertically with minimum expansion to the sides. So they won't be damaged by nearby mechanical parts and they're going to fit safely in tighter spots. And unlike air springs, these SumoSprings are going to require no maintenance or adjustment. These Jounce-style springs are made here in the USA and they are custom designed to fit your vehicle and they're going to install easily, no drillings required. And as you can see, it comes with the necessary hardware to install these. An instruction sheet is included to walk you through the installation process. And again, I mentioned earlier that the weight capacity at 50% compression is 1,400 pounds. However, these springs will not increase your vehicle's weight carrying capacity, so you do not want to exceed your manufacturer's recommended weight limit. These do have a limited lifetime warranty. And that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
