When you’ve got extra weight up front like a plow, winch, or heavy gear, the front suspension can sag and ride harsh. The Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Front Axle fit between the coils to add cushioning and support. Their microcellular polyurethane foam core adjusts progressively—the more load you add, the stiffer they become—so your ride stays level and controlled even with heavy front loads.
These wedge-shaped helper springs sit between each coil loop to absorb shock and vibration that would otherwise travel straight through the suspension. The extra cushioning helps reduce driver fatigue on long days behind the wheel and takes out some of the harshness that comes when your stock coils are compressed tight under weight.
Loaded or not, these helper springs reduce body roll and help level your truck for more stable handling. By giving your front end extra support, steering feels tighter and more predictable when cornering, braking, or driving through uneven terrain.
Each doughnut-shaped insert features H-shaped channels that slip over the rungs of your coil springs. They install easily without special tools and require no maintenance once in place. Designed to work with a suspension system that’s in good condition, they enhance support without increasing your vehicle’s weight-carrying capacity.

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.

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.
