A heavy front load or rough trail can throw off handling and steering. These SumoSprings helper springs add up to 2,300 lbs of front axle support at 50-percent compression to keep your suspension level and steady. The microcellular urethane absorbs bumps and shocks, helping your factory suspension handle extra weight without bottoming out. You get better control and a smoother ride even when the terrain or load gets uneven.
The springs compress in stages depending on how much weight you’re carrying. With lighter loads, they compress easily for soft engagement and a comfortable ride. As the weight increases, they firm up by as much as 80 percent to provide extra support and stability. That progressive action keeps your front end from diving too much on bumps while still soaking up vibration when the road gets rough.
Each spring works on its own to support the side it’s on. That independent action helps balance off-center loads and reduces body roll when turning or crossing uneven ground. The result is steadier steering response and less sway when the path tilts or the surface changes.
Made from microcellular urethane, these springs handle temperatures from -25 F to 200 F and resist damage from oil, road salt, and UV rays. They compress vertically with minimal side expansion so they fit safely in tight spaces without rubbing nearby components. With no airlines or air pressure to maintain, they deliver consistent performance trip after trip with no upkeep required.
Installation is straightforward with a bolt-on design—some setups may need a single drilled hole per side. Once installed, there’s nothing to adjust or refill. The kit includes two jounce-style springs, two urethane bumpers, an installation wrench, and all necessary hardware so you can get solid suspension support without the hassle of air systems or routine maintenance.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the SumoSprings Custom Helper Springs for the front axle of your Jeep with a three inch lift. This is a custom fit part. It is designed to fit the 2007 to 2017 Jeep Wrangler JK Models, fits the 2018 and newer Jeep Wrangler JL models and the 2020 and newer Jeep Gladiator models. Now on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now these are off road specific helper springs.
These will upgrade your vehicle's front suspension for improved driver control and comfort. Now this kit here is for vehicles with a three inch lift or more. That's why it'll include these urethane bumpers for that extra lift. These will keep your vehicle level when you're off-roading, helps to absorb any bumps and shocks, even minimizes sway, and they offer progressive load control. That means these springs will compress according to the weight of the cargo.
So if it has a lighter load on it, the springs compress easily at first for a nice soft engagement and less bumpy ride. And if it has a heavier load on it, the springs will compress by as much as 80% for support. And these springs do work independently from each other, helps compensate for any off-center loads, reduce body roll during sharp turns, and they are made of a microcellular urethane. They do work in temperatures from a negative 25 degrees Fahrenheit to 200 degrees Fahrenheit, and they'll even resist damage that can be caused by oils, road salts, UV rays. They offer minimal lateral expansion, meaning these springs compress vertically instead of to the sides, so they aren't easily damaged when operating in tight spaces.
And what's nice about a kit like this is they're maintenance free, so there's no tubing to run or air pressure to monitor, like with your air springs. These are a very easy bolt-on installation though some of the specific applications might require drilling. It will include everything shown here on the table. The two jounce style springs, the two urethane bumpers right here, the installation wrench with the bolts, and a little tube of thread locker. These parts are made in the USA.
Now the weight capacity at 50% compression is 2300 pounds. But I do wanna mention that the SumoSprings will not increase your vehicle's weight carrying capacity. But that should do it for a look at the SumoSprings Custom Helper Springs for the front axle of a Jeep with three inch lift.
