Additional Info

Unbalanced loads and difficult loads are a constant reality. That's why Firestone makes Coil-Rite air springs. Coil-Rite stabilizes your vehicle to contribute to better braking and handling, even when handling poor road conditions and heavy loads. In turn, properly installed Coil-Rite air springs also help reduce tire wear and level your headlight beams.

W237604175 Coil-Rite air springs are designed for specific vehicles with coil spring suspensions. They sit inside your current coil springs to produce a variable spring rate. A variable spring rate allows for a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. The result? A better ride for all those inside your vehicle, and more responsive control as you drive.

Is Firestone Coil-Rite installation pretty straightforward? Yes. Coil-Rite air spring kits are packed with all of the pieces necessary for a quick, straightforward 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 connect to your vehicle's current spring seats. Switches, gauges, air tanks, and air compressors can be purchased 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.

Once installed, Coil-Rite air bags adjust easily with individual inflation valves so you can maintain ride comfort and a centered load. Maintaining a balanced load lessens body roll to increase vehicle stability. Coil-Rite air springs also help prevent bottoming out by cushioning the interaction between your vehicle's axles and frame and absorbing road shock.

With Coil-Rite air springs, changing seasons won't block you from hauling what you need to haul. 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.

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

Shop online or head to your local Coil-Rite retailer to buy a W237604175 Firestone Coil-Rite air spring kit.
