Additional Info

Perfect loads and perfect roads don't exist. That's where Firestone 4118 Coil-Rite air spring kits come in handy. Coil-Rite balances your to promote better braking and handling, even when handling poor road conditions and heavy loads. As a result, properly installed Coil-Rite car air springs also help level headlight beams and promote even tire wear.

Most vehicles with coil spring suspensions can take advantage of Coil-Rite air helper springs. The springs fit within the current coil springs to create a variable spring rate. A variable spring rate allows for 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 car, and more control and support while you drive.

Is Firestone 4118 Coil-Rite installation pretty straightforward? Of course! Firestone air spring kits come with everything you need for a speedy, easy installation. A majority of Firestone Coil-Rite car kits are no-drill, and most kits take about one to two hours to install. Coil-Rite air springs are crafted out of durable, elastic polyurethane and connect to your vehicle's current spring seats. Gauges, switches, air compressors, and air tanks are sold separately. The right air accessories make it easier for you to inflate or deflate your air springs from the comfort of the driver's seat.

After installation, Firestone 4118 Coil-Rite air helper springs adjust easily, from side to side, with independent inflation valves to support a centered load and ride comfort. Maintaining a balanced load lessens body roll to improve vehicle stability. By softening the interaction between your vehicle's frame and axles and absorbing road shock, Coil-Rite air springs also help prevent bottoming out.

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). North or south, summer or winter— take your vehicle where you want to go.

Firestone Coil-Rite air springs support 500 - 2,100 lbs. per set but do not change your car's overall weight-carrying capacity. Check your vehicle manufacturer's recommended weight limit before towing or hauling any load.

Buy a Firestone Coil-Rite air spring kit for your vehicle at a local Coil-Rite retailer. It's time to ride on air!
