Heavy gear like a snowplow or grille guard can make the front end sag and throw off steering feel. These Coil SumoSprings Custom Helper Springs fit between the turns of your front coil springs to add extra support right where it’s needed. The microcellular polyurethane foam core cushions and stiffens progressively as weight increases, helping your suspension stay level, absorb shocks, and keep your ride comfortable even with heavy front-end equipment in place.
Stock coils can bottom out or jar you over bumps when loaded down. Each helper spring has an inner core of microcellular polyurethane foam that compresses gradually, soaking up vibration and impact instead of transferring it into the cab. The more weight you add, the firmer they get, so you keep traction and control without sacrificing comfort on rough surfaces or uneven roads.
When your front suspension starts to dip or roll, steering and braking can feel unpredictable. These inserts add stiffness between your coils to help control body movement through turns or sudden stops. With extra load support up front, your truck stays balanced and settled, giving you more confidence when maneuvering with heavy gear mounted or when driving on winding roads.
These helper springs are molded from durable microcellular polyurethane foam that resists abrasion, oil, road salt, and UV damage. They hold up through extreme temperatures without cracking or fading. Once installed between the coil rungs using the H-shaped channels, they stay firmly in place with no maintenance required—just dependable performance every time you head out to work or clear snow.
Adding support doesn’t take a full shop setup. These inserts install by hand between the individual coil turns on your existing front suspension—no special tools or permanent modifications needed. With two helper springs included in the kit and no maintenance required once in place, it’s a simple way to toughen up your suspension for heavier loads up front.

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?

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.

Hey Robert. These do fit a wide range of vehicle old and new. They are fitted based off the spacing between the coils on the vehicle so it is very possible that your year of Colorado would be the same as an older vehicle. I know it's been a year but, If you can measure the gap between the middle coils to the nearest 1/16" with your vehicle as level as possible and unloaded, I can look into this for you.
