Polyair Red Series bags are designed to fit inside the coil of a coil sprung vehicle to assist the spring in supporting whatever load is placed in the vehicle (within manufacturers recommended gross vehicle weight rating). They help in eliminating “bottoming out” and improve ride, handling and stability. The air adjustability allows you to tune the ride you want, whether you’re hauling, towing or riding light! Made with tough, long-lasting, moulded polyurethane.
