Controllers and gauges are the interface between the driver and the air suspension system, letting you monitor tank pressure, individual bag pressure, and system status while precisely commanding height changes at each corner. Air Ride Direct stocks manual paddle-valve controllers, digital preset controllers with programmable ride height memory, and analog and digital gauge sets for dash or console mounting. A quality controller setup turns a basic bag-and-valve system into a precise, repeatable, easy-to-use air ride experience, whether you’re adjusting height at a stoplight or dialing in a show-ready stance.
