Description

Firestone #4112 "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. "Coil-Rite" air helper springs enable adjustment for varying loads and road conditions by inflating or deflating the air helper springs. Spring performance can be altered as easily as inflating a tire. Firestone "Ride Rite" air helper springs are installed between the frame of the vehicle and the suspension providing load support through the use of air pressure.
