4100 Firestone Industrial Helper Spring Kit

Discover the difference Coil-Rite air helper springs can make in improving the ride, handling and braking of your vehicle. Coil-Rite air helper springs provide extra support for coil springs in cars, minivans, vans, light trucks, RV’s and SUV’s. The adjustable Coil-Rite air helper springs will level your vehicle, provide a smoother ride, and assist with more effective braking and handling, even under heavy loading and adverse road conditions. Coil-Rite air helper springs are designed to fit inside existing coil spring suspensions, creating a variable rate spring. These air helper springs are made of durable, elastic polyurethane, providing years of comfort and stability to your vehicle. Firestone’s Coil-Rite air helper springs enable adjustment for varying loads and road conditions by controlling the air pressure in the air helper springs. Spring performance can be altered as easily as inflating a tire. The air springs will support 500 To 1000 Pounds per set.
