We offer a simple and efficient solution to enhance the performance of your vehicle’s rear coil spring suspension system - suspension air bags by BlackStone deliver the ultimate balance of a smooth ride and extra support for the coil springs when hauling or towing. They will eliminate sag when fully loaded or towing, prevent bottoming out, reduce body roll or sway on the road.
Available in a range of sizes and series to ensure compatibility with almost any vehicle featuring coil spring suspension.
How It Works
BlackStone air bags are air-fast rubber tubes that are inserted in the vehicle’s coil spring suspension – the mounting is easy and does not require a car lift or dissembling of suspension parts. BlackStone air bags can be used with most vehicles with coil spring suspension – for this item to be compatible with your vehicle, it is important that the shock absorbers are located outside the spring coils by design.
After BlackStone air bags have been inserted into the opening of rear coil springs, pump them up using a tire inflator or a foot pump, to ensure pressure is within the recommended range for your kit (e.g. depending upon your purpose and preferences, keep it at under ~12psi for general commuting, or add more air when towing; refer to the manual supplied with the kit for more detail). When in operative condition, BlackStone air bags would fill the space inside the coil springs and works as an additional spring unit and shock absorber for suspension.
