<p>An air suspension includes a crossover valve (50) in fluid communication with a manifold (42), a first set of springs (20a,20b) in fluid communication with the manifold through a first set of valves (46a,46b), and a second set of springs (20c,20d) in fluid communication with the manifold through a second set of valves (46c,46d). The crossover valve is movable between an open position to allow fluid communication to each of the first and the second sets of springs and a closed position that separates the first set of springs from the second set of springs.</p> |
