It connects the chassis/axle to the leveling valve arm, telling the valve when to add or exhaust air to keep the ride height constant. The kit is universal-style, adjustable from roughly 3-5/8 to 20 inches, and includes rubber connector ends, hose clamps, and mounting hardware. It typically gets replaced when the original linkage is bent, rusted, seized, or the rubber ends crack, causing erratic ride height or air leaks.
