Trailer Air Bag
SAF-Holland

This heavy-duty suspension component provides critical load-support and ride-height control in a trailer air-ride system. Engineered for durability under demanding highway conditions, it maintains consistent levelness across varying payloads and road surfaces, reducing tire wear and improving overall vehicle stability. The unit features an air inlet connection sized for 1/4 NPTF, enabling reliable, leak-resistant plumbing to the primary air supply, and a mounting interface with 3/4-16 UNF threaded holes for secure attachment to standard suspension brackets. Designed to integrate with SAF-Holland air-suspension networks, its robust internal seals and reinforced housing resist high-cycle loading and temperature fluctuations typical of long-haul operation. The VMRS code 016-008-001 categorizes it within the air-suspension subsystem, underscoring its role in managing air-chamber actuation and suspension response. Compatibility considerations include common trailer frames and axles that utilize the specified inlet and mount-thread configurations, as well as other SAF-Holland components that share the same suspension architecture. In service, it supports load distribution, enhances braking stability, and contributes to smoother rides when traversing undulating terrain, making it a foundational element for trailers requiring dependable height control and air-pressurized support.
