There are a lot of variables involved in designing and using a truck’s suspension system. The wide range of functions served by trucks means that a manufacturer cannot anticipate every variable when they are designing the suspension. There are a lot of unsafe conditions that can be created within a suspension, such as uneven ride height. That is why Firestone offers the Firestone air leveling kit. The Firestone air leveling kit is designed to use inflatable systems to level out the rear of a vehicle. This is very useful when transporting loads that are an awkward shape or are loaded unevenly. A truck that is not level is subject of control in the best conditions, not to mention when it is wet or slippery out. The Firestone air leveling kit is able to adapt to the varying load conditions and allow you to have a level bed. Because it is made by Firestone, you can be confident that it is an excellent quality part. Firestone has been around for a long time as a manufacturer of tires and other automotive equipment, and their longevity speaks for the high quality of their products, including the Firestone air leveling kit.
