Additional Info

Every load and road is different. So is every job. That's why Firestone makes Coil-Rite air springs. Coil-Rite levels and stabilizes your Ford Bronco, F100, or F150 to promote more effective braking and handling, even when hauling a heavy load or dealing with adverse road conditions. As a result, properly installed Coil-Rite air springs also help level headlight beams and promote even tire wear.

Most SUVs and trucks with coil spring suspensions can take advantage of Coil-Rite air helper springs. They fit inside the existing coil springs to produce 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 better ride for all those inside your Ford Bronco, F100, or F150, and more control and support as you add miles to the odometer.

Is it easy to install Firestone Coil-Rite in a Ford Bronco, Ford F100, Ford F150? You bet. Ford-specific Coil-Rite air spring kits come with all of the pieces necessary for a fast, simple 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 attach to your Ford's existing 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 your driver's seat.

After installation, Coil-Rite air helper springs adjust easily, from side to side, with independent inflation valves to support a smooth ride and even load distribution. Maintaining a balanced load lessens body roll to enhance vehicle stability. Coil-Rite air springs also reduce your chances of bottoming out by softening the interplay between your SUV or truck's frame and axle, and absorbing road shock.

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). Head north, south, east, or west— take your Ford Bronco, F100, or F150 where you want to go.

Firestone Coil-Rite air springs support 500 - 2,100 lbs. per set but do not change your vehicle's total weight-carrying capacity. Review your Ford owner's manual for vehicle-specific recommendations before hauling or towing any size load. Note that this kit, W237604102, is not in-bed hitch compatible.
