It connects the suspension's leveling valve to the axle, allowing the valve to automatically adjust air pressure to maintain a constant ride height. The rod can be cut to the desired length during installation and includes rubber ends, clamps, and mounting hardware. It is commonly replaced when the original linkage becomes worn, bent, or corroded, causing improper suspension height control or air leaks.
