Additional Info

There's no such thing as a perfect load or perfect road conditions. That's why Firestone makes Coil-Rite air springs. Coil-Rite balances your Hyundai, Jeep, or Lincoln to encourage better braking and handling, even when towing, hauling, and driving in challenging road conditions. As a result, Coil-Rite air springs also help level headlight beams and promote even tire wear.

Coil-Rite air springs are designed for SUVs with coil spring suspensions. They fit within the current coil springs to create a variable spring rate. Variable spring rates offer a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. What's the benefit? A steadier ride for your passengers, and more control and support while you drive.

Is Firestone Coil-Rite installation pretty straightforward? Yes. Your Hyundai, Jeep, or Lincoln Coil-Rite air spring kit includes all the necessary parts for a quick, hassle-free installation. A majority of Firestone Coil-Rite SUV kits are no-drill, and most kits take about one to two hours to install. Coil-Rite springs are made from elastic polyurethane and attach to your Hyundai, Jeep, or Lincoln's current spring seats. Air tanks, air compressors, switches, and gauges can be bought separately. Purchase additional air accessories for your Hyundai, Jeep, or Lincoln to monitor and adjust your SUV air springs from inside your vehicle.

Once installed, Coil-Rite air bags adjust easily with individual inflation valves so you can maintain a smooth ride and balanced load distribution. Maintaining a balanced load lessens body roll to enhance vehicle stability. Coil-Rite air springs also help prevent bottoming out by cushioning the interaction between your SUV'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 Hyundai, Jeep, or Lincoln where you want.

Coil-Rite air springs support 500 - 2,100 lbs. per set but will not increase your Hyundai, Jeep, or Lincoln's weight-carrying capacity. Review your owner's manual for vehicle-specific recommendations before hauling or towing any size load.
