Additional Info
Perfect loads and perfect roads don't exist. That's where Firestone Coil-Rite air spring kits come in handy. Coil-Rite technology balances your Cadillac, Chevrolet, or GMC to promote more effective handling and braking, even when driving in unfavorable road conditions or towing a heavy trailer. As a result, properly installed Coil-Rite SUV air springs also help level headlight beams and promote even tire wear.
Coil-Rite air helper springs can be installed on most SUVs with coil spring suspensions. They sit within the current coil springs to produce a variable spring rate. A variable spring rate allows for a higher spring rate in loaded conditions and a slower spring rate in unloaded conditions. The outcome? A gentler journey for everyone inside your SUV, and more control and support when you're behind the wheel.
Is it easy to install Firestone Coil-Rite in a Cadillac, Chevrolet, or GMC? You bet. Coil-Rite air spring kits come with all the necessary parts for a fast, hassle-free installation. Most Firestone Coil-Rite SUV kits are no-drill, with install times averaging one to two hours. Coil-Rite air helper springs are manufactured out of elastic polyurethane and fasten to your Cadillac, Chevrolet, or GMC's current spring seats. Switches, gauges, air tanks, and air compressors can be purchased separately. Purchase additional air accessories for your Cadillac, Chevrolet, or GMC to monitor and adjust your SUV 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 balanced load lessens body roll to promote overall vehicle stability. By softening the interaction between your Cadillac, Chevrolet, or GMC's frame and axles and absorbing road shock, Coil-Rite air springs also help prevent bottoming out.
Plus, shifting temperatures won't throw a wrench in your plans when you drive with Coil-Rite air springs. 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 SUV where you want to go.
For your safety, remember that Coil-Rite air springs will not increase your Cadillac, Chevrolet, or GMC's weight-carrying capacity. Always confirm manufacturer recommendations for hauling or towing before loading up.
