Additional Info

Perfect loads and perfect roads don't exist. That's one reason we designed Coil-Rite air springs. Coil-Rite technology balances your vehicle to contribute to more effective handling and braking, even when driving in unfavorable road conditions or towing a heavy trailer. As a result, Coil-Rite SUV air springs also help limit tire wear and keep headlight beams even.

Coil-Rite air helper springs can be installed on most SUVs with coil spring suspensions. They fit inside the existing 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 does that lead to? A gentler journey for everyone inside your SUV, and more responsive control as you drive.

Is it easy to install Firestone W237604124 Coil-Rite springs? You bet. Coil-Rite air spring kits come with 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 air springs are crafted out of durable, elastic polyurethane and connect to your vehicle's existing spring seats. Air tanks, air compressors, switches, and gauges can be bought separately. Purchase additional air accessories for your vehicle to inflate and deflate your SUV air springs from the comfort of your cab.

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

With Coil-Rite air springs, changing seasons won't block you from hauling what you need to haul. Firestone Coil-Rite air springs were made to function in temperatures between -40F (-40C) and 180F (82C). Head north, south, east, or west—drive your SUV in any direction, any time.

For your safety, remember that Coil-Rite air springs will not increase your vehicle's weight-carrying capacity. Always confirm your manufacturer's recommendations for hauling or towing before loading up.
