Description
Firestone #4134 "Coil-Rite" air bag helper springs are designed to fit inside the existing Ford Expedition coil spring suspension creating a variable rate spring. These air bags are made of durable, elastic polyurethane providing years of comfort and stability to your vehicle. Ford Expedition "Coil-Rite" air helper springs enable adjustment for varying loads and road conditions by inflating or deflating the air bag helper springs. Spring performance can be altered as easily as inflating a tire. Firestone "Coil Rite" air bag helper springs are installed between the frame of the Ford Expedition and the suspension providing load support through the use of air pressure.
