When heavy gear or accessories push down on the front end, steering and braking can feel off. These SumoSprings Solo helper springs add up to 1,250 lbs of front suspension support at 50-percent compression to keep your ride level and steady. They pick up the extra weight so your factory suspension doesn’t have to, helping improve control and keeping your headlights aimed where they should.
Road chatter and uneven pavement can make the front end bounce. The microcellular urethane design compresses easily for lighter loads and stiffens as weight increases. That progressive load control cushions bumps and absorbs shocks, giving you a smoother ride whether you’re carrying heavy gear up front or running light.
When a curve or a gust tries to push you around, these springs react independently on each side to keep the vehicle planted. That separate movement helps balance off-center loads and cuts down on body roll through corners so steering feels stable even on uneven ground.
Each spring is made from high-density microcellular urethane that resists oil, salt, and UV damage and works in temperatures from -25 F to 200 F. The vertical compression design limits side expansion, so the springs fit safely into tight spaces without rubbing against nearby parts. There’s nothing to inflate or monitor—just simple, maintenance-free load support that installs with no drilling required.

Today we're going to take a look at the SuperSprings Heavy Duty SumoSprings Solo Custom Helper Springs, this is for the front axle. Has a 2500lbs weight capacity. Now, this is a custom-fit part. It is designed to fit many different vehicles, so what we like to recommend is to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, these helper springs will upgrade your vehicle's front suspension, for improved driver control and comfort. Supports heavy front-end loads to keep your vehicle level, it'll help to absorb any bumps and shocks, and it'll help minimize sway.
It does use a progressive load control, which means the springs compress according to the weight of the cargo. Lighter loads, the springs will compress easily at first for soft engagement and a less bumpy ride. Then, if the load is heavier, the springs will compress by as much as 80% for support. Now, these springs are designed to work independently from each other, to compensate for off-center loads and reduce body roll during sharp turns. It is made of a durable, high-density microcellular urethane. It is designed to work in temperatures from a -25F to 200F.
It is also designed to resist damage that can be caused by oils, road salts, and UV rays. Has a minimal lateral expansion, so the springs will compress vertically instead of to the sides, so they aren't easily damaged when operating in tight spaces. They are maintenance-free: There's no tubing to run or air pressure to monitor like with air springs. It's a simple no-drill installation. Comes with the 2 Jounce-style springs that are included.
This part is made in the USA. Comes with a nice set of detailed instructions that show you how to install it on your vehicle. A few specs on this: The weight capacity on them is, at 50% compression would be 2500lbs. This is designed to work with a suspension system that is in good working order. A note I want to let you know is that the SumoSprings will not increase your vehicle's weight carrying capacity, so you do not want to exceed the manufacturer's weight limit of your vehicle. That should do it for the review on the SuperSprings Heavy Duty SumoSprings Solo Custom Helper Springs for the Front Axle, with a 2,500lbs weight capacity..
