When snowplows, winches, or heavy bumpers weigh down the front end, these helper springs keep things level and controlled. Each insert uses an inner core of microcellular polyurethane foam that progressively stiffens as weight increases, giving the front suspension extra support without affecting normal ride comfort. The more you load it, the firmer it gets—keeping the front from squatting and helping steering and braking stay consistent.
Long hours on rough terrain or bumpy roads can be hard on both you and your suspension. These wedge-shaped inserts fit between the individual coils to cushion impacts and absorb shock. The added cushioning smooths out jolts from potholes or uneven ground so your ride feels more composed, reducing driver fatigue during long work days or snow-clearing sessions.
Extra weight up front can make a truck lean or feel loose in corners. The Coil SumoSprings help reduce body roll by supporting each coil independently, keeping the front end more stable through turns and crosswinds. The suspension stays balanced and planted, improving overall control whether you’re pushing a plow blade or winding down a mountain road.
Harsh weather and heavy use can destroy ordinary rubber parts, but these helper springs are built to handle it. The durable microcellular polyurethane resists damage from abrasion, oil, road salt, and UV rays, and they withstand extreme temperatures without cracking or wearing out. They install easily between your existing coils and require no maintenance once in place—just dependable support every time you hit the road.

You mentioned that they had too much play and I wanted to see if you could send a picture of them installed.

The instructions stated that when you install them that you put the bottom on and move up or down on the spring until top is snug and pop in bottom. On my truck even on the ground there is no area where this happens.

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?
