Air Spring
SAF-Holland

This air spring is a key element of progressive suspension systems, delivering vertical compliance while maintaining ride height under varying payloads. The bellows shape and seals are designed to resist contaminants and maintain air pressure integrity, ensuring dependable operation through miles of service. When installed, it acts in concert with dampers to stabilize body pitch, reduce bottoming, and preserve steering response during braking and cornering. Regular maintenance includes leak checks, inflation verification, and mounting hardware inspections to prevent misalignment and abnormal wear. The parts interface with SAF‑Holland components to achieve predictable performance and long service life in heavy‑duty applications. For optimal results, monitor ride height and inspect for cracks or abrasion on mounting points. Source One Parts Center.
