Product Information

These unique Firestone air helper spring kit is designed specifically for the Dodge Ram 1500 with rear coils springs.  Included are Firestone "Coil-Rite" air bags which mount inside the factory coils springs along with Firestone "Work-Rite" load assist springs which mount to the frame and axle.

Designed to fit inside the existing 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. This enables 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. Installed between the frame of the Dodge Ram and the suspension providing load support through the use of air pressure.

Firestone "Work-Rite" load assist springs are made of injection molded microcellular urethane.  Designed to increase vehicle stability and reduce sway when the your vehicle is loaded.  Unloaded ride quality is not affected.  Work-Rite kits install to the vehicles frame and axle (download instructions below) to assist the factory suspension.  Installation is done in less than an hour with basic hand tools.
