A heavy front load can make your ride sag and throw off braking and steering. These SumoSprings Solo helper springs add up to 4,000 lbs of support at 50-percent compression to help keep the front end level and steady. They work with your factory suspension to bear the extra weight, improve control, and keep your headlights aimed where they should be.
Whether you’re carrying a lighter load or maxing out your front axle, these springs automatically adjust. The microcellular urethane compresses easily at first for soft engagement, then stiffens as the load increases—up to 80 percent compression under heavy weight. That progressive rate means fewer harsh hits on rough roads and better stability when things get heavy.
When one side of your vehicle dips or a curve leans you over, each spring reacts on its own to keep things balanced. This reduces body roll, helps with off-center loads, and keeps your front end planted through corners or uneven terrain. Steering feels more predictable and controlled, even when carrying extra gear up front.
Built from extra-high-density microcellular urethane, these helper springs handle temperatures from -25 F to 200 F and resist oil, salt, and UV damage. They compress vertically with minimal side expansion so nearby parts stay safe from contact. With no air lines, tubing, or pressure to monitor, you can install them once—no drilling required—and just drive.

Speaker 1: Today, we're taking a look at the Sumo Spring solo custom helper springs for the front axle. Now, this is a custom fit design, so to ensure that this is a fit for your vehicle, you can use the Vehicle Fit Guide which is located at etrailer.com.Now, these helper springs are designed to upgrade your vehicle's front suspension for improved driver control and overall comfort. They also do a great job at supporting heavy front end loads to help keep your vehicle level. They absorb bumps and road shocks, and they really help minimize the amount of sway that you experience in the front of the vehicle. They feature progressive load control. So, these springs will compress according to the weight of your cargo.
For lighter loads, the springs compress by as much as 80% for maximum support, and they work independently from one another to compensate for those off center loads and reduce body roll during sharp turns.They're constructed of a durable extra high density micro cellular urethane designed to work in temperatures ranging from negative 25 degrees Fahrenheit to positive 200 degrees Fahrenheit, and it resists damage that's typically caused by oils, road salts, and UV rays.Now, with these installed, they feature minimal lateral expansion. So, that means that these springs compress vertically instead of off to the side, so they aren't easily damaged when operating in tight spaces. My favorite feature is that they're maintenance free. There's no tubing to run or air pressure to monitor like with air springs. You install them and you forget about them.
With this part number, you'll get everything laid out here on the table. You get your springs, you get all the necessary brackets and hardware, and you get a tube of Thread Locker.Simple, no drill installation. The brackets are made from durable steel and feature a nice powder coated finish on them. The hardware's plated to resist rust and corrosion as well. Parts made in the U.S.A.
Weight capacity at 50% compression is 4,000 pounds. Just keep in mind the Sumo Springs will not increase your vehicle's weight carrying capacity, so be careful not to exceed that. That's going to do it for today's look at the Sumo Spring solo custom helper springs for the front axle.

30 Minutes for all 4?! That's got to be some kind of record, Dennis! Glad the process was nice and easy and I hope they serve you well. Let us know if you do end up needing to go to the heavier duty yellow option as well, we always like to get real life experiences from people. : ) Any more trips planned for the year?
