Precision Manufacturing & Quality AssuranceThe Turbo Kings AD-IS 1-Plug Air Dryer (5004050) is newly manufactured in-house and engineered to deliver OEM-level air-system protection. Designed as a direct replacement for the Bendix AD-IS, this unit is pressure-tested up to 150 PSI to ensure complete air-tight integrity, purge reliability, and governor response under real-world operating conditions.Each air dryer is built using BRV high-temperature O-rings, providing superior sealing and extended service life even under continuous heat cycles. Internal components are lubricated with HP-870 high-temperature synthetic grease to ensure smooth valve actuation and resistance to carbon buildup. A genuine Bendix D-2 governor is installed and calibrated to maintain precise cut-in and cut-out control within the 135–150 PSI range.Every assembly is purged, neutralized, and moisture-free prior to final sealing—ensuring maximum protection for your vehicle’s air suspension, braking, and emission-related systems.What Makes Turbo Kings Air Dryers DifferentTurbo Kings does not rely on generic imports or outsourced assemblies.
