Additional Info

Every load and road is different. That's one reason we designed Coil-Rite air springs. Coil-Rite technology balances your Land Rover Defender 90, Discovery, or Range Rover to promote more effective handling and braking, even when driving in unfavorable road conditions or towing a heavy trailer. In turn, Coil-Rite SUV air springs also help level headlight beams and promote even tire wear.

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 lead to a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. What's the benefit? A better ride for all those inside your Land Rover, and more support and control as you take on new roads and adventures.

Is Firestone Coil-Rite installation pretty straightforward? Yes. Land Rover Coil-Rite air spring kits are packed with all the necessary parts for a fast, trouble-free installation. Install time averages one to two hours, and most Firestone Coil-Rite kits are no-drill. Coil-Rite air helper springs are manufactured out of elastic polyurethane and fasten to your Land Rover's current spring seats. Air compressors, air tanks, gauges, and switches are sold separately. Purchase additional air accessories for your Land Rover to monitor and adjust your SUV air springs from inside your vehicle.

Once installed, your Land Rover Coil-Rite air springs are easy to adjust so you can maintain ride comfort and a centered load. A centered load reduces body roll to enhance vehicle stability. By absorbing road shock and softening the interaction between your SUV's axles and frame, Coil-Rite air springs help prevent bottoming out.

With Coil-Rite air springs, changing seasons won't block you from hauling what you need to haul. Coil-Rite air springs were designed to work in temperatures between -40F (-40C) and 180F (82C). North or south, summer or winter— drive your Land Rover where you want.

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

Point your dash in the direction of an authorized Coil-Rite retailer and get your Land Rover Firestone Coil-Rite air spring kit.
