Additional Info

Road conditions and load demands always change. That's why Firestone makes Coil-Rite air springs. Coil-Rite technology balances your SUV to assist in better braking and handling, even when hauling a heavy load or dealing with adverse road conditions. As a result, properly installed Coil-Rite SUV air springs also help reduce tire wear and level your headlight beams.

Most SUVs with coil spring suspensions can take advantage of Coil-Rite air helper springs. They sit inside your 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 steadier ride for your passengers, and more responsive control as you add miles to the odometer.

Is Firestone Coil-Rite 4108 installation pretty straightforward? Yes. Coil-Rite air spring kits come with all of the pieces necessary for a fast, easy 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 SUV's current spring seats. Gauges, switches, air compressors, and air tanks are sold separately. Purchase additional air accessories for your SUV to inflate and deflate your air springs from the comfort of your cab.

After installation, Firestone 4108 Coil-Rite air helper springs adjust easily, from side to side, with independent inflation valves to support a smooth ride and balanced load distribution. A centered load reduces body roll to enhance vehicle stability. Coil-Rite air springs also reduce your chances of bottoming out by softening the interplay between your SUV's frame and axle, 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— take your vehicle where you want to go.

Firestone 4108 Coil-Rite air springs support 500 - 2,100 lbs. per set but will not increase your SUV's weight-carrying capacity. Review your owner's manual for vehicle-specific recommendations before hauling or towing any size load.

Locate your nearest Coil-Rite retailer and get your Firestone 4108 Coil-Rite air spring kit.
