Additional Info

Road conditions and load demands always change. Firestone Coil-Rite air springs put you in control of your car's response. Coil-Rite balances your vehicle to help support more effective braking and handling, even when hauling a heavy load or dealing with adverse road conditions. In turn, properly installed Coil-Rite car air springs also help level headlight beams and promote even tire wear.

Most cars with coil spring suspensions can take advantage of Coil-Rite air helper springs. They fit within the existing coil springs to generate a variable spring rate. Variable spring rates lead to a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. The outcome? A more enjoyable ride for everyone inside your car, and more support and control when you're behind the wheel.

Is Firestone Coil-Rite installation easy? You bet. Your Coil-Rite air spring kit includes everything you need for a fast, simple installation. Install times average less than two hours, and a majority of Firestone Coil-Rite car kits do not require drilling. Coil-Rite air helper springs are manufactured out of elastic polyurethane and fasten to your car's existing spring seats. Switches, gauges, air tanks, and air compressors can be purchased separately. Purchase additional air accessories for your vehicle to monitor and adjust your car air springs from inside your vehicle.

Once installed, your Coil-Rite air helper springs can be adjusted manually with individual inflation valves to support ride comfort and a centered load. Maintaining a centered load helps curb body roll and promote overall vehicle stability. Coil-Rite air springs also help prevent bottoming out by cushioning the interaction between your car's axles and frame and absorbing road shock.

And with Coil-Rite air springs, you don't have to worry about shifting seasons standing in your way of a job well done. Firestone Coil-Rite air springs were made to function in temperatures between -40F (-40C) and 180F (82C). Summer or winter, north or south— drive your car where you want to go.

Coil-Rite air springs support 500 - 2,100 lbs. per set but will not increase your car's weight-carrying capacity. Check your manufacturer's recommended weight limit before towing or hauling any load.
