A vehicle and a height adjustment system for the vehicle are disclosed. A valve includes a member movable between a first position operating first and second piston mechanisms to raise an end of the vehicle to a first height, a second position operating the first and second piston mechanisms to lower the end of the vehicle to a second height and a third position maintaining the end of the vehicle at one of the first height and the second height. A first fluid line extends between the first piston mechanism and the valve to fluidly connect the first piston mechanism and the valve. Additionally, a second fluid line extends between the second piston mechanism and the valve to fluidly connect the second piston mechanism and the valve. The first fluid line and the second fluid line are fluidly connected to the valve independently of each other.
