When heavy gear or front-mounted equipment starts to weigh down your suspension, these Coil SumoSprings helper springs step in to keep things level. Each insert fits between the coils in your front suspension and adds progressive support—the more weight you carry, the stiffer they become. That means your ride height stays steady and steering response stays consistent even with added front-end load.
Bumps and jolts can wear you down fast, especially when the stock coils are already compressed. The inner core of microcellular polyurethane foam cushions every hit, softening harsh impacts and taking the edge off road shock. You’ll feel less bounce and vibration through the steering wheel while keeping better control over uneven roads.
When you corner or hit the brakes, the last thing you want is a front end that dives or leans. These inserts help reduce body roll by adding firm, even support across both sides of your suspension. With extra stability built into your coil springs, your truck feels more planted and predictable through turns and quick stops.
Made from durable materials that resist oil, UV rays, road salt, and abrasion, these helper springs are built to handle extreme temperatures and constant use. Once installed, there’s no air pressure to check or fittings to maintain—just dependable performance every time you hit the road.
Setup is straightforward—each spring inserts between the individual coils of your front suspension without special tools or extra parts. Once in place, they work quietly in the background, adding comfort and support without changing your factory ride height or requiring ongoing maintenance.

Ive had these on my van for a year now, and they are working quite well. I find that the ride is very smooth, without any sway, under all conditions - including high wind. I think the effect is subtle, and the rear Sumo Springs probably have the larger effect. But the front ones add that extra level of performance improvement, and Im glad I have them.

Wow, that sounds like such a difference in so many ways, Connie. I bet being able to have a normal conversation as well as a smooth ride makes the journey between destinations so much more enjoyable. What kind of travel plans do you have for the summer?

Took the van on a 4000 mile trip and all worked wonderfully especially on the highway in windy conditions.

One year later we have nothing but praise for this. Greatly smooths the ride and provides stability during windy conditions. Van made it easily 16,000 miles across the U.S., up the Alaska Highway and Dalton Highway to the Artic Ocean. Highly recommend.

Glad to hear they made that much of a difference! It's always kind of surprising how much so simple a thing can make such a difference! ^___^ Sounds like quite the road trip as well! Where all did you guys go?
