Additional Info
Every load and road is different. That's one reason we designed Coil-Rite air springs. Coil-Rite balances your Saturn, Toyota, Buick, or Chevrolet to encourage better handling and braking, even when handling poor road conditions and heavy loads. As a result, Coil-Rite SUV air springs also help limit tire wear and keep headlight beams even.
Most SUVs with coil spring suspensions can take advantage of Coil-Rite air helper springs. They fit within the current coil springs to create 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 better ride for all those inside your vehicle, and more responsive control as you add miles to the odometer.
Is Firestone Coil-Rite installation pretty straightforward? It sure is. Your air spring kit contains all of the pieces necessary for a speedy, trouble-free installation. Install times average less than two hours, and a majority of Firestone Coil-Rite SUV kits do not require drilling. Coil-Rite air springs are crafted out of durable, elastic polyurethane and connect to your Saturn, Toyota, Buick, or Chevrolet's current spring seats. Air tanks, air compressors, switches, and gauges can be bought 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 a centered load and ride comfort. A balanced load diminishes body roll to improve vehicle stability. Coil-Rite air springs also help prevent bottoming out by cushioning the interaction between your SUV'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. Coil-Rite air helper springs are designed to continue performing in temperatures between -40F (-40C) and 180F (82C). Head north or south— drive your Saturn, Toyota, Buick, or Chevrolet in any direction, any time.
Firestone Coil-Rite air springs support 500 - 2,100 lbs. per set but do not change your SUV's overall weight-carrying capacity. Review your owner's manual for vehicle-specific recommendations before hauling or towing any size load.
