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

Great system
Product works great. Needed some help to level out my escalade while towing a horse and trailer. This product works well and does the job. Installation was pretty easy - hardest part was squeezing the bag inside the spring. This system doesn't come with a T fitting so that both bags can be aired at the same time so I purchased it separate. I can now air up both bags at one time. (Equal air to both sides) trailer weight is 5600 lbs plus the weight of two horses 2700 lbs. this product helped tremendously
