The R-Series AM combines Reyco Granning’s familiar R-Series drive axle air suspension with the latest air supply module called AirMaster®.  The system is a turn-key bolt-in upgrade to replace the inferior factory leaf spring suspension on Shuttle Bus, Ambulance, RV and Work Truck applications with Ford, Ram, GM, and EV chassis.The R-Series was designed to improve ride quality, manage body height, and permit kneeling relative to a factory leaf spring.

The AirMaster is factory certified leak free, eliminates air-line freezing, and dramatically improves compressor life relative to legacy air supply systems.  The R-Series AM combination enhances vehicle productivity, driver comfort, and resale value.  The outcome is an astounding 457 pounds lighter, with an acquisition cost of $2,500 less than the Liquid Spring CLASS® equivalent.

The R-Series® or AirMaster® can also be purchased separately.
