The AirMaster® by Reyco Granning is the latest air control system for suspensions in the Light/Medium Duty markets. The AirMaster® incorporates an electronic height control system and was designed to improve the durability and reduce the installation complexity for Reyco Granning’s R-Series® suspensions for Ford, GM and RAM trucks. In addition, the AirMaster® can be used as a compact stand-alone suspension air control system for vehicles equipped with hydraulic brakes or no on-board air compressor.

The AirMaster® is factory certified leak free, comes pre-plumbed with an integrated air dryer to eliminate air-line condensation and associated line freezing, while a proprietary CPU control module eliminates unnecessary air compressor cycling leading to dramatically improved compressor life relative to legacy air supply systems.

The R-Series® and AirMaster® can be purchased separately or they can be purchased together to form a TransportMaster® system, click here for more information.
