It automatically adjusts air pressure in the suspension bellows when loads change, so the chassis stays level without over‑ or under‑adjusting. The kit includes a lever arm and linkage and can be mounted on either side of the vehicle. You replace it when the old valve fails to hold height, leaks, or causes slow, bumpy ride response.
