Firestone 4100 Coil-Rite Manual-Fill Front Kit for Chevrolet/GMC - 4100

Every road demands something of your Chevy/GMC, and so does every load. That's one reason we designed Coil-Rite air springs. Coil-Rite technology balances your Chevrolet/GMC to help support better handling and braking, even when towing, hauling, and driving in challenging road conditions. As a result, properly installed Coil-Rite SUV air springs also help reduce tire wear and level your headlight beams. Coil-Rite air helper springs are made for SUVs with coil spring suspensions. They fit within the current coil springs to create a variable spring rate. Variable spring rates offer a slower spring rate in unloaded conditions and a higher spring rate in loaded conditions. The result? A smoother ride for you and your passengers, and more control and support when you're behind the wheel. Is it easy to install Firestone Coil-Rite in a Chevrolet/GMC? Yes. Chevrolet/GMC Coil-Rite air spring kits are packed with everything you need for a speedy, easy installation. Install times average less than two hours, and a majority of Firestone Coil-Rite SUV kits do not require drilling. Coil-Rite springs are made from elastic polyurethane and connect to your Chevrolet/GMC's current spring seats. Switches, gauges, air tanks, and air compressors can be purchased separately. Purchase additional air accessories for your Chevrolet/GMC to monitor and adjust your SUV air springs from inside your vehicle. Once installed, your Coil-Rite air helper springs can be adjusted manually with individual inflation valves to support even load distribution and ride comfort. Maintaining a centered load helps curb body roll and 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. Plus, shifting temperatures won't throw a wrench in your plans when you drive with Coil-Rite air springs. Coil-Rite air springs were designed to work in temperatures between -40F (-40C) and 180F (82C). Summer or winter, north or south— take your Chevrolet/GMC where you want to go. Chevrolet/GMC Coil-Rite air springs support 500 - 2,100 lbs. per set but will not increase your SUV's weight-carrying capacity. Always confirm Chevrolet/GMC's recommendations for hauling or towing before loading up.
