Chevrolet / GM Heavy Duty Coil Springs
ATS Springs offers a full line of heavy duty coil springs for Chevrolet and GM trucks and vans. These upgraded coils are engineered to support increased front-end weight while restoring proper ride height and suspension geometry.
By installing heavy duty coil springs, you can eliminate front-end sag caused by added equipment and improve load support on the front suspension. These HD coil springs are especially beneficial for snow plow applications, heavy bumpers, winches, and other front-mounted accessories.
Understanding Coil Spring Suspension
What Is a Coil Spring Suspension?
A coil spring suspension uses steel coil springs to support the weight of the vehicle, absorb road impacts, and maintain ride height. On many Chevrolet and GM trucks, coil springs are used in the front suspension to provide controlled ride quality and precise steering response.
The coil spring works together with:
- Control arms
- Shock absorbers
- Steering components
to keep the front axle properly positioned while allowing vertical movement over bumps and uneven road surfaces.
Why Coil Springs Sag Over Time
Factory coil springs are designed for stock vehicle weight. Over time—or when additional weight is added—the springs can lose tension. Common causes of coil spring sag include:
- Snow plows
- Heavy-duty bumpers or winches
- Commercial or plow prep use
- High-mileage wear and fatigue
When coil springs sag, the front of the vehicle sits lower, reducing suspension travel and affecting alignment.
Benefits of Heavy Duty Coil Springs
Upgrading to heavy duty coil springs provides several key advantages:
- Restores or increases OEM ride height
- Improves front-end load capacity
- Reduces bottoming out under load
- Allows proper alignment without add-on spacers
- Improves steering control and braking stability
For trucks that regularly carry or push heavy loads, HD coil springs help protect suspension components from premature wear.
Why Heavy Duty Coil Springs Matter for Snow Plow Trucks
Snow plows place constant weight on the front suspension. Without proper spring support, this can lead to:
- Excessive front-end sag
- Poor plow height control
- Accelerated wear on ball joints and shocks
Heavy duty coil springs are designed to carry the added plow weight without compromising ride height or alignment, making them a critical upgrade for plow-equipped Chevrolet and GM trucks.
