2,300-lb Capacity. These maintenance-free microcellular urethane springs upgrade your vehicle's front suspension. Some specific applications may require drilling.

Specs:
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.
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.
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.
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, with the exception of Jeep Wrangler JKs, which may require a single hole drilled for each side.

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.
Haven’t installed them yet but have heard good things about them. The help finding them from etrailer has been great.
