Heavy gear or equipment up front can make your ride nose down and affect steering and braking. These SumoSprings Solo helper springs add up to 1,000 lbs of support at 50-percent compression to keep the front end level and stable. They help your factory suspension handle the load, absorb bumps and shocks, and keep your headlights aimed where they should for confident driving.
Not every trip has the same weight, so these springs react to what you’re carrying. With lighter loads, they compress easily for softer engagement and a smoother ride. Add more weight and they stiffen up—compressing by as much as 80 percent—to keep things supported and under control. The progressive action means a steady feel whether you’re just cruising or hauling extra weight.

When a curve or side wind tries to push you around, these springs work independently to keep each side planted. That independent action helps reduce body roll when you turn sharply or drive on uneven ground, keeping your ride stable and predictable through corners or gusty stretches of highway.
Made from durable microcellular urethane, these springs hold up through harsh weather from -25 F to 200 F. They resist abrasion, oil, salt, and UV damage that can wear out other materials. Minimal lateral expansion keeps them compact so they won’t rub against nearby components. And since they’re maintenance-free with no air lines or pressure to check, they’re ready to go day after day without extra work.
You don’t need a lift or special tools to get these on. The custom-fit design mounts easily with no drilling required. Two jounce-style springs come in the kit so you can upgrade both sides of your front suspension and get back on the road with better support and control.

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?

That is awesome to hear! It must be such a relief to not have to put so much energy into controlling the wheel while driving now.

Appreciate you leaving a review Austin, It's always nice when a product exceeds expectations and these springs have been highly rated. Are you typically off road or do you plan on towing?
