Additional Info

Perfect loads and perfect roads don't exist. Firestone Coil-Rite air springs put you in control of your SUV's response. Coil-Rite balances your Jeep to contribute to more effective handling and braking, even when handling poor road conditions and heavy loads. As a result, properly installed Coil-Rite SUV air springs also help reduce tire wear and level your headlight beams.

Coil-Rite air springs are designed for SUVs with coil spring suspensions. They sit inside your current coil springs to produce a variable spring rate. Variable spring rates lead to a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. What's the benefit? A more enjoyable ride for everyone inside your SUV, and more control and support as you drive.

Is Firestone Coil-Rite installation pretty straightforward? It sure is. Your Jeep Coil-Rite air spring kit includes everything you need for a quick, hassle-free installation. Install times average less than two hours, and a majority of Firestone Coil-Rite SUV kits do not require drilling. Coil-Rite springs are made from elastic polyurethane and connect to your Jeep's current spring seats. Air tanks, air compressors, switches, and gauges can be bought separately. Purchase the right air accessories for your Jeep to inflate and deflate your SUV air springs from the comfort of your cab.

Once installed, your Jeep Coil-Rite air springs are easy to adjust so you can maintain even load distribution and ride comfort. A centered load reduces body roll to increase vehicle stability. Jeep Coil-Rite air springs also help prevent bottoming out by cushioning the interaction between your SUV's axles and frame and absorbing road shock.

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). Head north or south— drive your Jeep in any direction, any time.

For your safety, remember that Jeep Coil-Rite air springs will not increase your vehicle's weight-carrying capacity. Review your Jeep owner's manual for vehicle-specific recommendations before hauling or towing any size load.

Head to your local Coil-Rite retailer and buy a Firestone Coil-Rite air spring kit for your Jeep today.
