Additional Info

Road conditions and load demands always change. That's where Firestone Coil-Rite air spring kits come in handy. Coil-Rite levels and stabilizes your INFINITI/Nissan to help support more effective 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 sit within the existing coil springs to create a variable spring rate. Variable spring rates offer a higher spring rate in loaded conditions and a slower spring rate in unloaded conditions. The result? A smoother ride for you and your passengers, and more support and control when you're behind the wheel.
Is it easy to install Firestone Coil-Rite in an INFINITI/Nissan? It sure is. Coil-Rite air spring kits come with all the necessary parts for a fast, straightforward installation. Most Firestone Coil-Rite SUV kits are no-drill, with install times averaging one to two hours. Coil-Rite air springs are crafted out of durable, elastic polyurethane and connect to your INFINITI/Nissan's existing spring seats. Gauges, switches, air compressors, and air tanks are sold separately. Purchase additional air accessories for your INFINITI/Nissan to monitor and adjust your SUV air springs from inside your vehicle.
Once installed, your INFINITI/Nissan Coil-Rite air springs are easy to adjust so you can maintain a smooth ride and even load distribution. Maintaining a balanced load lessens body roll to promote overall vehicle stability. INFINITI/Nissan 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). Summer or winter, north or south— drive your INFINITI/Nissan where you want to go.
Firestone Coil-Rite air springs support 500 - 2,100 lbs. per set but do not change your SUV's overall weight-carrying capacity. Check INFINITI/Nissan's recommended weight limit before towing or hauling any load.
