Additional Info

There's no such thing as a perfect load or perfect road conditions. That's one reason we designed Coil-Rite air springs. Coil-Rite stabilizes your Jeep Gladiator to help support better braking and handling, even when hauling difficult loads or driving in inclement weather. In turn, Coil-Rite air springs also help reduce tire wear and level your headlight beams.

Most vehicles with coil spring suspensions can take advantage of Coil-Rite air helper springs. They fit within the current coil springs to produce a variable spring rate. Variable spring rates lead to a higher spring rate in loaded conditions and a slower spring rate in unloaded conditions. What does that lead to? A more enjoyable ride for everyone inside your vehicle and more support and control behind the wheel.

Is Firestone Coil-Rite installation pretty straightforward? You bet. Jeep Gladiator Coil-Rite air spring kits are packed with all of the pieces necessary for a quick, straightforward installation. The average install time is about an hour or two, and most Firestone Coil-Rite kits are conveniently no-drill. Coil-Rite air springs are crafted out of durable, elastic polyurethane and fasten to your Jeep Gladiator's existing spring seats. Gauges, switches, air compressors, and air tanks are sold separately. Purchase the right air accessories for your Jeep Gladiator to inflate and deflate your air springs from the comfort of your cab.
 
Once installed, your Jeep Gladiator Coil-Rite air springs are easy to adjust so you can maintain ride comfort and a centered load. Maintaining a balanced load lessens body roll to improve vehicle stability. By absorbing road shock and softening the interaction between your vehicle's axles and frame, Coil-Rite air springs 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— take your Jeep Gladiator where you want to go.
 
Jeep Gladiator Coil-Rite air springs support 500 - 2,000 lbs. per set but will not increase your vehicle's weight-carrying capacity. Always confirm Jeep's recommendations for hauling or towing before loading up.
