Additional Info

Every load and road is different. Firestone Coil-Rite air springs help you adapt to the job at hand. Coil-Rite technology balances your vehicle to assist in better handling and braking, even when driving in difficult road conditions or towing an unbalanced trailer. As a result, Coil-Rite car air springs also help limit tire wear and keep headlight beams even.

Most cars with coil spring suspensions can take advantage of Coil-Rite air helper springs. They fit within the current coil springs to produce a variable spring rate. Variable spring rates offer a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. The result? A smoother ride for you and your passengers, and more control and support when you're behind the wheel.

Is it easy to install Firestone Coil-Rite? Yes. Your Coil-Rite air spring kit contains everything you need for a quick, 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 springs are crafted out of durable, elastic polyurethane and fasten to your vehicle's current spring seats. Air compressors, air tanks, gauges, and switches are sold separately. You can purchase separate compatible air accessories to inflate and deflate your car air springs from the comfort of your cab.

Once installed, your Coil-Rite air springs are easy to adjust so you can maintain a smooth ride and even load distribution. A balanced load diminishes body roll to enhance vehicle stability. By absorbing road shock and softening the interaction between your car's axles and frame, Coil-Rite air springs help prevent bottoming out.

Plus, shifting temperatures won't throw a wrench in your plans when you drive with Coil-Rite air springs. Coil-Rite air helper springs are designed to continue performing in temperatures between -40F (-40C) and 180F (82C). North or south, summer or winter— drive your car where you want.

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

Point your dash in the direction of an authorized Coil-Rite retailer and buy a Firestone Coil-Rite air spring kit.
