Additional Info

There's no such thing as an easy load or perfect load, especially when you take your SUV to new destinations. Firestone Coil-Rite air springs help you adapt to the job at hand. Coil-Rite levels your Jeep Wrangler to help support more effective braking and handling, even when hauling a heavy load or dealing with adverse road conditions. In turn, 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 existing coil springs to create a variable spring rate. Variable spring rates lead to a higher spring rate in loaded conditions and a slower spring rate in unloaded conditions. The result? A steadier ride for your passengers, and more control and support as you add miles to the odometer.

Is it easy to install Firestone Coil-Rite in a 2WD Jeep Wrangler Unlimited? It sure is. Your Jeep Wrangler Coil-Rite air spring kit contains everything you need for a fast, straightforward installation. Install times average less than two hours, and a majority of Firestone Coil-Rite SUV kits do not require drilling. Coil-Rite air helper springs are manufactured out of elastic polyurethane and fasten to your Wrangler's existing spring seats. Air compressors, air tanks, gauges, and switches are sold separately. The right air accessories make it easier for you to inflate or deflate your Jeep Wrangler air springs from the comfort of the driver's seat.

Once installed, your Jeep Wrangler Coil-Rite air springs are easy to adjust so you can maintain even load distribution and ride comfort. A balanced load diminishes body roll to increase vehicle stability. By softening the interaction between your Jeep'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. Coil-Rite air helper springs are designed to continue performing in temperatures between -40F (-40C) and 180F (82C). Head north or south— drive your SUV where you want to go.

For your safety, remember that 2WD Jeep Wrangler Coil-Rite air springs will not increase your vehicle's weight-carrying capacity. Review your Jeep Wrangler owner's manual for vehicle-specific recommendations before hauling or towing any size load.

Select a Coil-Rite retailer and get your Jeep Wrangler Firestone Coil-Rite air spring kit.
