If you're looking for a smoother ride for your vehicle that has a coil spring suspension, Firestone Coil-Rite air helper springs are what you need. Designed to fit inside existing coil springs to create a variable spring rate, Coil-Rite will level your vehicle and assist with more effective braking and handling, even under heavy loading and adverse road conditions.Coil-Rite enables you to control the air pressure in the air helper springs so you can make adjustments for varying loads and road conditions. Spring performance can be altered as easily as inflating a tire.Firestone Coil-Rite air helper springs are made of durable, elastic polyurethane, providing years of comfort and stability to your vehicle. The air springs will support 500-1000 lbs. per set (not to exceed vehicle's GVWR). Coil-Rite Air Helper Springs are designed to work in temperatures between 180 �F (82 �C) and -40 �F (-40 �C).

More than seventy years ago, Firestone started developing a full air-based suspension for passenger cars. Firestone Airide air springs were installed on the new line of general Motors buses in the late 50's. Later that decade, air springs began to gain popularity in luxury vehicles. Over the next 20 years, technology improvements in other suspension components, such as compressors and valves, helped support the growth of air suspension. In the 1970's, Ford Motor Company incorporated air suspension in the Lincoln Town Car and Continental. Firestone has continued to be innovative in product design, material selection and customer service, providing our customers with improved ride quality and safe load-carrying capabilities.
